Royal New Zealand Infantry Regiment


The Royal New Zealand Infantry Regiment is the parent administrative regiment of regular and reserve infantry battalions in the New Zealand Army.

History

Formation

The New Zealand Infantry Corps was formed on 9 January 1947, consisting of a single Regular infantry battalion, the New Zealand Regiment, and eleven Territorial Force Infantry Regiments;
However, The formation of the regular infantry battalion was only one in name and it was decided that the "1st New Zealand Regiment" should be held in abeyance until such a time that a "Regular" Battalion was raised.
The New Zealand Infantry Corps war granted royal status in July 1947. In August 1947 the New Zealand Regiment was reorganised with the two Infantry Battalions in Jayforce joining the New Zealand Regiment:
The 2nd and 3rd Battalions were disbanded in 1948 following their return to New Zealand.
During 1948 amalgamations further reduced the TF Infantry Regiments to nine;
On 2 August 1957, official authority was granted to raise and train the first "Regular" Infantry Battalion in New Zealand history. Under the command of Lt-Col W. R. K. Morrison DSO, the 1st New Zealand Regiment would be New Zealand's land force commitment to the British Commonwealth Far East Reserve, The 1st Battalion, The New Zealand Regiment was deployed to Malaya from October 1957 as part the 28th Commonwealth Infantry Brigade Group. Between 1958 and 1964 the NZ Regiment would rotate 3 Battalions through Malaya;
This deployment would be unique in New Zealand military history, as it would be the first time that families would accompany a New Zealand overseas military deployment to an overseas location.
In 1963 the 2nd Battalion now based in New Zealand was reorganised as a Depot for the 1st Battalion.

Infantry reorganization

On 1 April 1964 all units of the Royal New Zealand Infantry Corps were reorganised into the Royal New Zealand Infantry Regiment and re-designated as;
During the Indonesia-Malaysia confrontation which began on 20 January 1963, 1 RNZIR would be committed to the conflict from September 1964, seeing service in Mainland Malaysia and Borneo.
1 RNZIR would initially see action in September 1964 when Indonesian paratroopers landed in Johore, 1 RNZIR was one of the few Commonwealth units in the region and with the New Zealand government's permission hunted down the infiltrators. The following month, 52 Indonesian soldiers landed in Pontian on the Johore-Malacca border and were also captured by New Zealand soldiers. 1 RNZIR would later deploy to Borneo where they would combat Indonesian cross border infiltration. The Indonesia-Malaysia Confrontation officially ended in May 1966.

Vietnam War

During the Vietnam War, 1 RNZIR which remained at Terendak Camp in Malaysia, would contribute a series of Rifle companies to serve with the 1st Australian Task Force in South Vietnam.

Creation of the 1st Australian Task Force

In May 1965 the United States government committed its 173rd Airborne Brigade to South Vietnam in a combat role. Being part of the ANZUS pact Australia and New Zealand were asked to contribute military forces too. Up until this time the Australians had committed an Army training team and New Zealand had committed some non-combatant engineers. In response to the United States' request, the Australian government committed an infantry battalion, its 1st Battalion, Royal Australian Regiment, and a squadron of armoured personnel carriers in June. The 1st Australian Logistic Support Group was established at Vung Tau in support. A headquarters for the force, Commander Australian Army Force Vietnam, was established in Saigon. New Zealand committed a battery from the Royal Regiment of New Zealand Artillery in July and established its own headquarters at Saigon. The Australian infantry regiment and the New Zealand artillery battery served under operational control of the 173rd Airborne in Biên Hòa Province. initially, 1 RAR defended the Bien Hoa Air Base near Saigon while the paratroopers from the 173rd fought in the highlands. After two months the Australian infantry were deployed on operations in the field. In September the Australian government committed an Artillery battery, an engineer troop from the Royal Australian Engineers, a light aircraft unit equipped with Sioux light helicopters, 104 Signals Squadron from the Royal Australian Corps of Signals and further logistics support personnel. Disparities in operational methods between the U.S and Australian forces were soon evident and in March 1966 the U.S and Australian governments decided to create an Australian task force with its own Tactical area of responsibility. In May 1966 a second Australian battalion arrived, 5th Battalion, Royal Australian Regiment to help establish the new permanent base at Nui Dat in Phước Tuy Province. Phước Tuy was to be designated the TAOR for the new task force. In June 1966 the Australian and New Zealand elements were detached from the 173rd Airborne to commence as the 1st Australian Task Force. 1 RAR returned to Australia and was replaced by 6th Battalion, Royal Australian Regiment
Over the next several months the new task force at Nui Dat was brought up to strength, adding a second artillery battery, an SAS Squadron, engineers from 17th Construction Squadron, intelligence elements, and Light Aid Detachments for cavalry and artillery. 1 ATF Headquarters were established with its own Defence and Employment Platoon. Two American artillery units were also located at Nui Dat: A Battery 2/35 U.S Artillery, and 1/83 Company U.S Artillery. Eight UH-1B Iroquois helicopters from No. 9 Squadron RAAF which was based at 1ALSG at Vung tau provided air support for the task force. 5th Transport Company Royal Australian Army Service Corps, also stationed at Vung Tau provided transport logistics and mechanical engineering.
The Enemy
Lying on South Vietnam's southern coast, three-quarters of Phước Tuy was covered with rainforest and grassland. The South Vietnamese Government's authority over Phước Tuy was limited almost entirely to the provincial capital city of Bà Rịa.
The principal communist units in Phước Tuy were main forces from the 274th and 275th Regiments of the VC 5th Division headquartered in the Mây Tào Mountains at the very north east of the province. Operating in Phước Tuy, Biên Hòa and Long Khánh Provinces it comprised both South Vietnamese guerrillas and North Vietnamese Army Regular forces. The 274th Regiment was the stronger and better trained of the two, based in north-west Phước Tuy in an area known as the Hat Dich secret zone, with three battalions numbering 2,000 men. The 275th Regiment was based in the Mây Tào Mountains in an area known as the May Tao Secret Zone, and mainly operated in the east of the province. It consisted of three battalions with a total of 1,850 men. The Viet Cong D445 Provincial Mobile Battalion also operated throughout the province with an estimated strength of 350 men. Its headquarters were located in the Minh Dam Secret Zone in the Long Hải Hills near the south coast. Additionally, there were three district-based Viet Cong Local Force units: C23, the Xuyên Mộc District Company; C25, the Long Đất District Company; and C41, the Châu Đức District Company. The VC had built up an extensive cadre and political organisation that reached into every town and village.
Phước Tuy's villages and hamlets in the south were grouped around Routes 15, Route 2,, Route 44, and Route 23 The province's roads were dangerous, subject to ambush and passable only with heavy escort. Military estimates placed the number of communist troops in the province at about 5,000. These troops relied on the support of many of Phước Tuy's villages, each of which had its own VC Guerrilla Squad. Not many villagers were supporters of the South Vietnamese government which they saw as too remote, often corrupt, and not concerned with the concerns of every peasant farmer, such as the reform of land ownership laws. The village of Dat Do, along Route 23, was home to 54% of the provincial population, most of whom were Viet Cong and North Vietnamese supporters, and was concentrated around the best rice fields in the province.
The Minefield
What would ultimately prove to be a tactical blunder by 1 ATF Command and account for the majority of Australian and New Zealand casualties throughout the war, was the laying of a minefield over a 10 km area from Dat Do to the coast. During the laying of the minefield in May 1967, 13 Australian sappers were killed by faulty ordnance, accidents, stress, and distractions by enemy actions. By June 1967, close to 23,000 "jumping jack" mines had been laid by the Australian engineers within a 100-meter-wide strip of cleared ground between a double row of fences. Security of the minefield proved to be ineffective and the VC thereafter simply uplifted the mines and re-used them against the Australians and New Zealanders

Victor Company

The first New Zealand infantry contribution to Vietnam was a 182-man rifle company which arrived from Terendak Military Camp in Malaya on 13 May 1967. Soldiers from C and D Companies 1 RNZIR with six months left in their two-year tour were selected. Most had seen operational service with British forces as part of the 28th Commonwealth Infantry Brigade Group, 17th Gurkha Division in Malaya and Borneo. The Company was named "V" for "Vietnam", with the phonetic "Victor." For the first two weeks, Victor Company served with the outgoing 6 RAR.
V Company's first shakedown mission, Operation Wellington, was a three-day Search and destroy mission around Nui Dat resulting in 1 VC killed and 1 wounded and 5 suspects captured for questioning.
On 27 May V Company relieved A Company 6 RAR at "The Horseshoe", a permanent Fire support base north of the village of Dat Do, some 8 km from the task force base. V Company came under direct command of 1 ATF headquarters, remaining at The Horseshoe until 3 July, and throughout this time effectively built the position from a rudimentary defended position to a fully dug-in and bunkered, fortified base.
While the New Zealanders were at The Horseshoe, 2nd Battalion, Royal Australian Regiment arrived from Australia to replace 6 RAR.
On 3 July, V Company was relieved by A Company, 2 RAR and returned to Nui Dat, thereafter coming under operational control of 2 RAR. Despite being under 2 RAR operationally, V Company did maintain some command autonomy for all non-operational administrative matters which were reported to the New Zealand HQ V Force Headquarters in Saigon.
V Company's first operation with 2 RAR was Operation Paddington which was a combined Search-and-destroy operation with 7th Battalion, Royal Australian Regiment, Army of the Republic of Vietnam and U.S forces. This operation also established a fire support base at Xuyên Mộc. 1 ATF also provided security for engineer land clearing operations over 136 square kilometers adjacent to and north east of Xuyên Mộc. This operation proved very successful with 171 bunkers, 200 meters of trench, three fighting positions, 32 tunnels and 34 other military structures destroyed. A further 138 bunkers, 14 tunnel entrances, 180 meters of trench, and 34 other military structures were damaged and later destroyed by airstrike. 31 VC were killed with no New Zealand casualties.
V Company's next operation with 2 RAR was in Operation Cairns This was a Search-and-destroy operation south east of Dat Do and east of the freshly completed barrier minefield. It was known that the VC used the wooded areas east of Dat Do as a base and obtained supplies from nearby villages. Although newly laid, the VC were already uplifting the mines from the minefield and re-laying them or booby trapping them elsewhere. 2 RAR's casualties in this operation were all from mine detonations, none from gunfire. There were no New Zealand casualties.
V Company then spent the next ten days conducting ambushes and search and destroy patrols in the area of the Long Phuoc hills. The company returned to Nui Dat having discovered and destroyed five VC camps and captured quantities of weapons, with 10 VC dead and two wounded taken prisoner, with no New Zealand casualties.
V Company's next operation with 2 RAR was Operation Atherton which began on 16 August. Four teams of Combat engineers from 1 Field Squadron were tasked with conducting land clearing actions. The operation was designed to clear the Communist infiltration routes into the east, maintain pressure on the VC base area, and to secure the eastern flank of the task force base. During a patrol on 2 September 1967 an accidental mine detonation resulted in one New Zealander killed and one other wounded. Operation Atherton concluded the following day, on 3 September.
On 4 September V Company, 2 RAR, and 7 RAR were committed to Operation Ainslie, an operation to clear an area of Route 2 and relocate the inhabitants from three villages under VC influence to a new Australian-built village at Ap Suoi Nghe. An additional phase was added to the operation as a result of intelligence gained and V Company and 7 RAR were deployed in blocking positions in anticipation of elements from VC 274th Regiment to cross Route 2. Several contacts were made with 18 VC killed with one Australian casualty and one wounded. There were no New Zealand casualties. By 21 September the village had been built and the villagers moved in. A total of 1132 persons, comprising 246 families, were resettled.
V Company's final operation with an Australian battalion was in Operation Kenmore consisting of a Search-and-destroy operation in an area between Xuyên Mộc and Cape Hồ Tràm along the southern coast. With C Company at the Horseshoe and D Company providing security at Ap Suoi Nghe, V Company joined A and B Companies of 2 RAR for the operation. 7 RAR was also deployed. The operation overall resulted in 16 VC killed with weapons, ammunition, ordnance and mines captured. Over 12 tonnes of rice and 12 lb of salt were destroyed, and many documents obtained. 230 bunkers, 300 weapon pits and 74 military structures were also destroyed. There were no Australian or New Zealand casualties.
V Company returned to The Horseshoe 26 October and remained there until 12 November where it was replaced by a new Victor company, also from 1 RNZIR in Malaya. The first Victor company completed their tour with 1 killed and 2 wounded.
From The Horseshoe, the new Victor Company's first tasks were to provide security to Dat Do Village and conduct local ambushes and patrols.

Whisky Company

In December 1967 the Australian government committed a third infantry battalion, 3rd Battalion, Royal Australian Regiment which arrived in Vietnam on 12 December. As well, the New Zealand government committed a second infantry company, Whisky Company, also from 1 RNZIR in Malaya, which arrived in Vietnam on 17 December.
W Company's shakedown operation was Operation Lawley during 22 and 23 December 1967, consisting of a cordon and search of the village of Ngãi Giao, north of the task force base while V2 Company remained at the Horseshoe.
On 28 December W Company relieved V2 Company at The Horseshoe and V2 Company joined 2 RAR and 7 RAR in the ongoing Operation Forrest, a search and destroy operation near the Phước Tuy-Long Khánh provincial boundaries which had begun on 23 November. The operation concluded 5 January 1968.
Operation Duntroon was the next 1 ATF operation involving V2 Company, 2 RAR, and 7 RAR which was a search and destroy operation conducted in conjunction with U.S 1st Brigade, 9th Infantry Division's Operation Akron V in the Hat Dich area. On the evening of 13 January, while providing left flank protection, a platoon-size group of VC were caught in V2 Company's ambush initiating a firefight that resulted in eight VC killed and 10 weapons captured, with no casualties to V2 Company. The operation concluded 21 January.
At The Horseshoe, W Company conducted patrolling, ambushing, and check point duties, with several clashes with the enemy. During a patrol on 26 January, one member of W Company was killed and another wounded from a mine detonation.
1968 Tet Offensive
The most significant of 1 ATF operations in 1968 was Operation Coburg, which was mounted between 24 January and 1 March in the border area between Phước Tuy and Long Khánh provinces shortly after the Communist forces launched the Tet Offensive. Operation Coburg was the first operation conducted by 1 ATF outside of Phước Tuy and was aimed at denying the VC the ability to attack the large American bases at Long Binh and Biên Hòa. 2 RAR and 7 RAR were deployed with 3 RAR remaining at Nui Dat to provide base defence. All three troops of engineers from 1 Field Squadron accompanied each of the battalions to provide mine clearing and additional patrols. A Fire support base was established north-east of Biên Hòa and east of Long Binh. The two Australian artillery batteries were moved to the FSB.
With W Company stationed at The Horseshoe, V2 Company joined 2 RAR for the operation. On 26 January B Company, 2 RAR fought a two-hour action against about 25 VC entrenched in a bunker system. On the same day 9 Platoon, C Company, 2 RAR also assaulted and occupied a camp initially believed to be of similar strength and held it for 19 hours after repeated attacks from a VC force estimated to be of company strength. On 28 January, whilst providing flank security, V2 Company engaged in a series of skirmishes which resulted in 12 VC dead and many weapons captured with two New Zealanders wounded. On 1 February V2 Company suffered their first killed in action in a contact with the enemy. On the morning of 7 February, V2 Company was attacked by elements of three companies from VC 274th Regiment. Fighting was the fiercest that New Zealand troops had faced up to this time, and over the course of an hour the attack was successfully repelled with the assistance of artillery support from the Australian 108th Battery as well as from mortar fire. The VC withdrew following the arrival of gunships, leaving behind 13 dead and a number of blood trails. Nine New Zealanders were wounded in the engagement, six of whom subsequently required evacuation by helicopter.
A second Fire support base had been established earlier by the Americans 17 km east of Biên Hòa near the village of Trang Bom and the U.S 2/35th Field Artillery had arrived 28 January, with C Company, 3 RAR arriving as base defense the following day. 7 RAR was relieved by 3 RAR on 11 February and 7 RAR returned to Nui Dat to begin preparations for their return to Australia. A Company was left to defend the base, while the other three 3 RAR rifle companies continued Reconnaissance-in-force operations around expected enemy exfiltration routes east of Biên Hòa. On 12 February W Company was relieved at The Horseshoe and joined 3 RAR in reconnaissance operations. 161 Field Battery, RNZA arrived at the FSB on 14 February, the same day as 2 RAR and V2 Company left the operation to return to Nui Dat. W Company continued on Coburg under operational control of 3 RAR. On 14 February a member of W Company was accidentally wounded by friendly fire upon his return from a patrol. The following day W Company made three contacts with the enemy resulting in two VC killed and one wounded.
Unfortunately the FSB had been established too close to the village and base activities could easily be seen by the villagers, some of whom were VC spies. On the night of 18 February the Viet Cong launched a massive rocket and mortar attack on the FSB, primarily targeting the U.S and New Zealand artillery positions. Two subsequent waves of VC attacks were held off over two hours with the loss of three members of 3 RAR, one American from 2/35th Field Artillery, and four members of 1st Field Sqn who were caught outside the perimeter while on a standing patrol. 22 Australians and three Americans were wounded. This was the first time 1 ATF had experienced a fire support base being subjected to a ground assault. The base was immediately reinforced by C Company, 3 RAR just in time for a second assault on 19 February, this time with no losses. On 24 February W Company was diverted from relieving 3 RAR at the FSB to report back to Nui Dat in preparation for a new operation with 2 RAR. On 28 February a third assault occurred against the FSB, also beginning with a mortar attack, but the assault was repelled by mortar fire, forcing the attackers to retreat. Three Americans were wounded.
New Zealand casualties in Operation Coburg were two killed and 15 wounded, including one killed and two wounded from 161 Battery. The operation concluded 1 March 1968. Australian casualties in the operation were 17 killed and 61 wounded. American casualties were one killed and six wounded. Communist casualties were 145 confirmed killed, 110 wounded, and five taken prisoner. Large quantities of weapons and equipment were also captured.
Although Operation Coburg was mounted too late to prevent the attacks on Saigon, the Australians and New Zealanders successfully disrupted the communist lines of communication and inhibited their withdrawal efforts, causing heavy casualties in the process.
On 27 February 1968 the Australian government sent two troops of Centurion tanks from its 1st Armoured Regiment to South Vietnam, each with four tanks plus two tanks with the squadron headquarters. Two bulldozer tanks and two bridgelayer tanks were also committed. A third troop was created out of the headquarters tanks, and by August the squadron was brought up to its full strength of 26 tanks. Australian and New Zealand infantry would work very closely with these tank troops during their time in Vietnam.
Operation Pinnaroo began on 27 February 1968, with V2 Company and W Company joining 2 RAR to strike at the base areas of VC D445 Battalion in the Minh Dam Secret Zone located in the Long Hải Hills. This was also the first 1 ATF operation with Australian tanks from the newly arrived 1st Armoured Regiment. The operation started with a clearing operation in the village of Long Điền where it was thought retreating Viet Cong had moved into. On 29 February, the last day of the sweep, one member of V2 Company was wounded in a contact with the enemy. The battalion was then ordered to conduct patrols to the south and east, between the village and the Nui Da Dung hills.

2 RAR/NZ (ANZAC) March 1968 – May 1968

Formation of ANZAC Battalion
1 March 1968 saw the formation of the "ANZAC Battalion" which was a merger of A, B and C Companies of 2 RAR with V2 and W Companies of RNZIR and renamed 2 RAR/NZ. It was the first official integration of Australian and New Zealand forces into an infantry battalion under the same name since World War I and the only Australian battalion to have five rifle companies. The Battalion deputy commander was an RNZIR Officer. A NZ Component was established at Nui Dat to manage national administration of the New Zealand contingents within 1 ATF.
Operation Pinnaroo continued into March with C Company remaining at The Horseshoe and the other four 2 RAR/NZ companies patrolling toward the northern slopes of the Long Hải Hills. On 1 March six members of W Company were wounded from two separate mine incidents. On 4 March, W Company and one of the APC troops conducted a cordon and search of the village of Tam Phouc. On 7 March, one member of W Company was wounded by a mine detonation during the search of a house. On 8 March 3 RAR joined the operation, operating from a Fire support base 7 km south of the Horseshoe. On 9 March, W Company ambushed five VC from the Long Điền Guerilla Unit, killing three and capturing two. A patrol on 18 March resulted in another of W Company wounded by a mine. V2 Company did not experience any further casualties of their own during the remainder of the operation. 2 RAR/NZ left Pinnaroo on 24 March, leaving 3 RAR to continue.
2 RAR/NZ and one company from 7 RAR next commenced Operation Ashgrove Tram, which was a cordon and search based on suspicions that VC were hiding in the coastal township of Long Hai, having retreated there during Pinnaroo. Out of 2085 persons screened nine VC suspects were apprehended, 80 persons were detained with ID card irregularities, and 106 draft dodgers and deserters were arrested and handed over to South Vietnamese authorities. The battalion returned to Nui Dat on 26 March to conduct local patrols.
Clearing the minefield
Realising the mistake they had made in laying a minefield which essentially served to arm the enemy, 1 ATF command set about engaging the Australian Engineer Combat Teams to sweep and clear the barrier minefield with APC, tank, and infantry elements of 1 ATF in support. The first of a series of operations to this end was Operation Cooktown Orchid, launched on 1 April. Each phase was assigned to specific companies from 2 RAR/NZ involving land clearing, Reconnaissance-in-force, ambushing, patrolling, and clearing of the barrier minefield. The Australian 17th Construction Squadron and U.S 34th Engineer Group provided the heavy machinery.
V2 Company was deployed in the area of Hoa Long, south of Nui Dat. The company was to establish a platoon ambush on the western approaches to Hoa Long to prevent the movement of VC supply parties. On the night of 5 April a ten-man enemy patrol was caught in a V2 Company ambush with six killed and no New Zealand casualties.
W Company began Operation Cooktown Orchid IV on 6 April with C Squadron, 1st Armoured Regiment conducting a Reconnaissance-in-force in the Xuyen Moc area 14 VC camps were destroyed and a quantity of equipment captured by the time the operation concluded on 9 April.
Operation Cooktown Orchid V began for W Company on 10 April with W Company in command of 2 Troop from C Squadron and elements of 3rd Cavalry and the Australian Combat engineers to clear mines from the barrier minefield with the tanks towing heavy platforms. On that night three members of W Company were wounded by a booby trap. The mine-clearing operation began on 11 April but then terminated in the same day due to damage to the tanks. The tanks returned to Nui Dat for repairs and base defence. On 12 April a recently laid mine was detonated, seriously wounding two New Zealanders, with one dying a month later. Following a cordon and search of a local village on 14 April, the company returned to Nui Dat to conduct local patrols.
On the following day 3 RAR returned from Operation Pinnaroo. By the end of the operation 3 RAR had suffered heavy casualties, the majority from accidental mine detonations.
On 18 April W Company relieved C Company 2 RAR, who had been given Operation Cooktown Orchid I, in protecting 17th Construction Squadron undertaking land clearing with bulldozers and Rome plows on the northern slopes of the Long Hai mountains. W Company was relieved by the 1 ATF Reinforcement Unit and returned to Nui Dat on 22 April.
On 25 April, 2 RAR/NZ and 3 RAR were deployed to Long Khánh Province to join Operation Toan Thang I which had commenced two and a half weeks earlier. The operation, involving U.S, ARVN, and Royal Thai Volunteer Regiment forces was launched in anticipation of a VC offensive against Saigon and the military installations of Long Binh and Bien Hoa. Subsequent clearing operations undertaken by W Company were without incident. A mishap on 27 April whereby Australian mortars accidentally shelled V2 Company's night harbour resulted in five New Zealanders wounded. On 3 May W Company discovered a large battalion-sized VC camp with 250 bunkers which had been abandoned. 3 RAR was relieved by 1 RAR on 5 May and 1 RAR and 2 RAR/NZ were redeployed further north into Bien Hoa Province. The North Vietnamese Army struck Saigon on 5 May but failed to achieve the success of its earlier Tet Offensive in February. By 7 May the enemy attack on Saigon had been successfully repulsed by the American and ARVN forces. For the Australians and New Zealanders who were elsewhere conducting ambushing tasks on likely approach routes to the Bien Hoa complex very few contacts were made and on 10 May 2 RAR/NZ returned to Nui Dat to prepare 2 RAR and Victor 2 Company for their departures from Vietnam. From 20–23 May W Company joined C Company 2 RAR to protect a land clearing operation near Ap Soui Nghe as part of Operation Toolong.

4 RAR/NZ (ANZAC) May 1968 – May 1969

In May 1968 Victor 2 was replaced by Victor 3. The new Victor Company also brought a RNZE Assault pioneer section. By the end of their six-month tour Victor 2 had sustained 1 killed and 20 wounded. Hereafter the tour of duty for all RNZIR companies was extended to twelve months.
On 1 June 2 RAR was replaced by 4th Battalion, Royal Australian Regiment and the joint Australian and New Zealander infantry forces became 4 RAR/NZ Again, the battalion was commanded by an Australian with a RNZIR 2IC.
The new Victor Company deployed to The Horseshoe on 5 June. 4 RAR with W Company completed their first shake-down operation, Operation Redwing on 10 June which was a one-day search operation in the Binh Ba rubber plantation and jungle areas north-west of Route 2 where it was known VC held meetings, collected taxes from the villagers, disseminated propaganda, and gathered rice from the plantation workers.
4 RAR then joined with W Company for Operation Kosciusko on 15 June. The battalion moved to an area south west of Route 15 to conduct search-and-destroy patrols. A number of contacts were made with one member of W Company injured from a claymore blast in one. A quantity of weapons, food, and equipment were seized and a battalion-sized training camp was discovered and destroyed. The operation concluded on 20 June.
While at The Horseshoe, a major contact occurred on 22 June when V3 Company tracked and killed three VC on a patrol. The company came upon an enemy camp with 70-80 VC. A ferocious firefight ensued with one New Zealander killed in one of the first volleys. The company was pinned down but managed to fight off two enemy assaults. Helicopter gunships and mortar support saved the patrol from being wiped out. Four members of V3 Company were wounded in the battle with 3 confirmed VC killed. V3 Company remained at The Horseshoe to the end of July.
From 23 June the battalion took part in Operation Toan Thang II along the Biên Hòa-Long Khahn border. The operation's objectives were to deny enemy infiltration routes into Saigon and to identify rocket-launching sites. 4 RAR/NZ was sent to assist 1 RAR which was relieving the U.S 199th Light Infantry Brigade. Since commencing the operation 10 days earlier, 1 RAR had seen no signs of the enemy and had made no contacts. 4 RAR/NZ patrolled west of 1 RAR's position. During patrolling, W company had one contact with the enemy. On 3 July 1 RAR was relieved by 3 RAR. W Company then provided security for the operation's Fire support base until 18 July.
4 RAR/NZ's next operation, Operation Merino saw W Company initially positioned as Fire support base defence while V3 Company patrolled with 4 RAR along Route 15, near the village of Thai Thien. On 20 July the firebase was moved some 4 km east of Route 15 to an area known as "The Blackstone Trail" where patrolling continued. Following airstrikes and artillery bombardment on a bunkered enemy camp that had been found by V3 Company on 22 July, that night all companies mounted an attack on the enemy camp but the area had been decimated and vacated. By the end of the operation the battalion had participated in 33 days of continuous operations.
1 August saw W Company deploy on Operation Lyre Bird which was a land clearing operation from Route 15 to the north operating from two fire bases and with W Company providing defence for the engineers from 17th Construction Squadron and patrolling the area.
Also on 1 August, V3 Company moved out by APCs and with the tanks of 3 Troop to a site four kilometres north of Ngãi Giao village on the western side of Route 2 to establish a Fire support base in support of 3 RAR. V3 Company provided defence for 161 Field Battery RNZA and B Battery, 2/35th US Artillery. The company patrolled in the vicinity of the fire support base without contact, returning to Nui Dat on 13 August and then redeploying two days later to Ap Sui Nghe to patrol and establish observation posts. V3 Company was relieved on 26 August.
During W Company's land clearing operation, on 4 August one of the fire bases was fired on with RPGs badly damaging two of the bulldozers and injuring two members of W Company. Despite numerous contacts with VC in the area, after five weeks Operation Lyre Bird ended on 4 September resulting in a cleared trail through the jungle some 200 metres wide and 13,500 metres long.
On 7 September Operation Innamincka was launched which was a cordon and sweep against a suspected enemy camp in Nui Nhan involving both RNZIR companies and B and C Companies from 4 RAR, with D Company at The Horseshoe. There were two minor contacts during the initial sweep, with 1 VC killed and 1 wounded by V3 Company. For the second stage the operation became a battalion Reconnaissance-in-force further west. V3 Company flew to the western edge of the area of operation and B Company moved south, while C and W companies commenced sweeping south-west. W Company made minor contact, but the other companies saw and heard nothing of significance. The operation finished on 12 September.
With D Company remaining at The Horseshoe, the remainder of 4 RAR/NZ was next tasked with a three-part operation, Operation Hawkesbury beginning on 12 September. The 4 RAR/NZ companies were moved into blocking positions east of Route 2 on the western edge of Thua Tich, in the north east of the province. The operation also involved 1 RAR sweeping east to west and 3 RAR in a defensive position to the south. It was hoped for 1 RAR's sweeping actions to push the enemy into 2 RAR/NZ's positions. B and C Companies were moved to the area of the Blackstone Trail to carry out a Reconnaissance-in-force. V3 Company and W Company were both deployed north to the area of the Courtenay rubber plantation to intercept a consignment of rockets believed to be moving from east to west. V3 Company took up blocking positions on the western edge of the plantation while W Company swept westward. On 14 September one member from W Company was killed by a sniper during a patrol. A further search of the area led W Company to discover a system of tunnels with caches of equipment, food, and medical supplies.
Acting on new intelligence, 1 ATF Command redeployed 2 RAR/NZ and 1 RAR north into the Hat Dich area on 15 September. On 16 September, V3 and W companies joined C and B companies at the "Blackstone Trail." All companies made contacts with the enemy. V3 Company ambushed and killed 10 VC over the next two days. C Platoon found an enemy camp of 150 bunkers, killing two VC and capturing a large amount of equipment and detailed enemy maps. Documents indicated the area was the headquarters of VC 84 Rear Service Group. Unfortunately the following day, while C Company were still in the bunkers, American fighter planes accidentally strafed the position injuring 14 Australians. W Company discovered a number of fortified positions which had been hastily vacated and confirmed two VC killed. The battalion returned to Nui Dat on 24 September.
Upon return to Nui Dat, W Company made it known that they wished to return to an area where well-worn tracks had been discovered on a previous operation, but not checked out. On 28 September W Company, with a section of mortars from 4 RAR, mounted an independent operation, Operation Sceptre, in the area of Ngãi Giao, on Route 2 north of Ap Sui Nghe. The Company established its own Fire support base and patrolled from it. Results were 8 VC killed and one captured with no New Zealand or Australian casualties.
V3 Company also did an independent operation: Operation Stirrup Cup. This was a one-day operation carried out to the east of Route 15, near Thai Thien, as part of a "rice-denial" programme. On 3 October the company deployed to the area by APC, discovering rice and other food supplies defended by a caretaker group of VC. The company recovered and destroyed 56,200 lb of rice, 1,000 lb of salt and other food and materials. One VC was killed during the contact.
Upon completing their own operation, W Company returned to Nui Dat on 6 October to undertake base defence duties and to prepare for Operation Capital. This would be Whisky Company's last operation.
The pink Citroën
Operation Capital was a two-phase operation conducted again in the area of the Thua Tich where the VC 84 Rear Services Group supplied the local Communist forces and grew crops and stored large caches of supplies and equipment. 3 RAR was deployed to the area on 12 October and 4 RAR/NZ was deployed on 13 October. W Company and 104 Field Battery established their Fire support base on the edge of the Courtenay rubber plantation with W Company providing base security. V3 Company worked with C and D Companies of 4 RAR patrolling east. On 16 October, V3 located a large enemy camp complete with HQ command area, first aid post, printing equipment, kitchens, huts with bunkers underneath, female living quarters, and 19 bunkers with trenches. Due to the size of the camp, V3 Company and the engineers took two days to demolish it. The battalion flew back to Nui Dat on 30 October with the intent of luring the VC out to where they had been and then having the battalion redeploy to the area to catch them by surprise as the second phase of the operation. 4 RAR/NZ, less W Company which remained at the base in preparation for their departure from Vietnam, redeployed three days later to this end. The second Whisky Company arrived in theatre on 8 November 1968 and began training at The Horseshoe. By the end of their tour Whisky 1 had suffered 3 killed and 17 wounded. The new Whisky Company also brought an Assault pioneer team.
While Whisky 2 trained at the Horseshoe, V3 Company and C Company 4 RAR engaged in local patrols and ambushes. On 16 November, V3 Company was fired on during an ambush resulting in one New Zealander killed. During a patrol on 27 November, V3 Company discovered an abandoned 1948 Citroën Traction Avant car with two bullet holes in the back window and with the licence plate "NVA 601" near the Courtenay rubber plantation. Although they were told to get rid of it by headquarters, V3 Company brought the car back to Nui Dat by way of an Iroquois helicopter from 9 Squadron, RAAF. Members of V3 company attempted to get the car running but were unsuccessful. The car was given to the 102nd Field Workshops, Royal Australian Electrical and Mechanical Engineers and was fixed up by off-duty members. The car was painted pink and donated to a Sister of the Royal New Zealand Nursing Corps at the 1st Australian Field Hospital at Vung Tau, to be used by her and other nurses to drive around in. The vehicle was passed on over the following years. Operation Capital II concluded on 22 November with 3RAR returning to Nui Dat, however, 4RAR/NZ remained in the area until 30 November. Both phases of the operation amounted to 48 days of continuous operations.
Battle of Hat Dich
On 11 December 4 RAR/NZ, less both RNZIR companies, returned to the Long Khánh-Biên Hòa border as part of Operation Goodwood which had commenced a week earlier. V3 Company remained at Nui Dat as base defence while the new Whisky company continued at The Horseshoe. The operation was launched in response to increased VC activity that suggested a Tet offensive for 1969 was being planned. Australian, U.S, Thai, and South Vietnamese forces were put under 1 ATF command for the operation with 1 RAR as the main Australian battalion. W2 Company were replaced by V3 Company at The Horseshoe and joined operations on 31 December. On 1 January 1969, the newly arrived 9th Battalion, Royal Australian Regiment deployed from Nui Dat to relieve 1 RAR in the Long Thanh district and 1 RAR was redeployed along Route 15 on a new operation in support of Goodwood. 9 RAR and 4 RAR/NZ continued on with the primary operation. An accident on 11 January resulted in a British national from W2 Company being killed in a friendly fire incident. On 13 January 4 RAR/NZ returned to Nui Dat for a break and was relieved by 1 RAR who were then redeployed on Goodwood.
On 20 January W2 Company commenced a three-day operation with 2/48th ARVN Battalion and 586 South Vietnamese Regional Force Company in Operation Toan Thang. No contacts were made.
Operation Goodwood ended on 27 January. On the same day Operation Goodwood, Phase II began with 4 RAR/NZ deployed to the Hat Dich to replace 1 RAR which had returned to Nui Dat to make preparations for their return to Australia. W2 Company rejoined the battalion the following day. During the night of 29 January, W2 was attacked from three directions with RPG, small arms, and machine gun fire resulting in three New Zealanders wounded. The enemy withdrew after artillery fire was called in. On 30 January, V3 Company was relieved by C Company at The Horseshoe and joined the operation. On the same day all four rifle companies made contacts with small groups of VC all within only a few hours of each other. Three members of V3 Company were wounded in their contact. A VC camp was discovered and quantities of ammunition, medical supplies and rice were captured. By 7 February a FSB was established near the village of Phuoc Long, further north and west of Route 15. V3 Company deployed to the south of the village, with B Company to the north and W2 Company to the east. Ambushes and patrols by all three companies continued to make contacts with the enemy, with the New Zealand companies alone claiming a dozen enemy killed and wounded over the three-day period of 8–10 February. On the night of 15 February D Company ambushed 15 VC in six sampans travelling along the Suoi Cau river. Two sampans were sunk and six VC killed before the survivors made it to the river bank to engage the Australians with small arms and RPGs. On 16 February B Company was attacked by VC in a bunker system resulting in two Australians killed and three wounded. Five tank crew were also wounded when their tank was hit multiple times by VC RPGs. Later intelligence suggested that the position had been occupied by the headquarters of the 274th Regiment and one of its battalions. Operation Goodwood, Phase II concluded on 19 February, with both phases having amounted to 78 days. 4 RAR/NZ and 9 RAR returned to Nui Dat to immediately commence with Operation Federal as a follow-up. Australian casualties in Goodwood amounted to 21 killed and 91 wounded. ARVN and RF casualties amounted to 31 killed and 81 wounded. The Americans suffered seven wounded. North Vietnamese and Viet Cong losses amounted to at least 245 killed, 39 possibly killed, 45 wounded and 17 captured, during 274 separate contacts. Nearly 2,000 bunkers were uncovered and many destroyed, while more than 280 rocket propelled grenades, 70 anti-personnel mines, 490 grenades and 450 pounds of explosives were captured overall. Although there were few major actions, the operation was considered a success by 1 ATF Command and the Communist forces in the Hat Dich area were significantly weakened.
For Operation Federal 4RAR/NZ was deployed east of the U.S base at Long Binh and south of Song La Buong River while 9 RAR was deployed to the north. Enemy forces anticipated were elements from VC 5th Division, namely 274th VC Regiment and the newly relocated 33rd NVA Regiment. The enemy were expected to attack from the east. V3 Company was furthest north with B Company to the south and W2 Company alongside the river. On 23 February W2 Company had three small contacts with enemy groups up to six strong. That same night the company position and a ten-man standing patrol both came under attack by an estimated company-strength force with the resultant firefight lasting almost two hours. Four members of the patrol were wounded. During the fight, one enemy soldier accidentally mistook the New Zealand patrol for his own men and in turn was shot dead. He was later identified as the Commanding Officer of the NVA D525 Engineer Reconnaissance Battalion whose task it had been to breach the defenses of Long Binh. With AC-47 Spooky air support from the Americans, the enemy withdrew. The following morning, seven enemy dead were found with an estimated 20 more fatalities from the artillery and mortar fire.
5 RAR relieved 9 RAR on 10 March, having arrived in February and concluding their first battalion operation in the northern and eastern parts of the Nui Dinh Hills. With a total of 26 enemy killed, 12 wounded and 4 captured, 4 RAR/NZ was relieved by 5 RAR on 24 March after 33 days in the area. W2 Company's contact was the biggest contact of the operation.
Operation Overlander commenced in Biên Hòa Province on 8 April 1969 with C, D, V3, and W2 Companies sent in to search for VC forces that had been earlier pushed south by 5 RAR. On the following day three members of V3 Company were wounded from a grenade blast in a contact with a VC party. On 13 April, V3 Company found a series of bunker systems and supply caches yielding key documents revealing details of the VC supply group supporting the Communist forces in the Hat Dich secret zone. On the same day V3 Company found large quantities of ammunition, explosives and workshop tools and materials. W2 Company provided security for the Fire support base established for the operation. On 15 April W3 Company encountered strong resistance from a VC camp with superior numbers, resulting in seven VC killed with five New Zealanders wounded. With 14 VC killed and six wounded in the operation, the battalion again returned to Nui Dat on 17 April.
"Pacification" and "Vietnamization"
On 16 April, 1 ATF was advised of a change to operational priorities, with top priority given to eradicating the VC presence and influence among the civilian populations, followed by the upskilling of the South Vietnamese military forces. These programs were known as "Pacification" and "Vietnamization" respectively as part of the "Winning Hearts And Minds" strategy being undertaken by the Americans. 1 ATF would be increasingly called upon to provide support to a number of civil community reconstruction projects and assist in the training of South Vietnamese forces.
4 RAR/NZ's last battalion operation was Operation Stafford from 17 April to 1 May conducted in and around the Binh Ba rubber plantation. The objective was to try and destroy the local C41 Company. Intelligence had also revealed that VC 274th Regiment may have moved into the area following recent task force operations. It was also hoped for to encounter the Binh Ba and Duc Thanh Guerrilla units. An FSB was hastily established and W2 Company was positioned as base defence while V3 Company and C and D Companies patrolled. V3 Company was particularly successful, managing to capture a high-value VC operations officer from 274th Regiment on 28 April, ending their tour on a high.
On 8 May, Victor 3 was replaced by Victor 4. By the end of their tour Victor 3 had suffered two killed and 22 wounded. The new Victor Company conducted operations with Whisky 2 and 4 RAR while 4 RAR made their preparations to return to Australia.
On 11 May, following a request from the Americans at Blackhorse Base Camp in Đồng Nai Province, the home base of 11th Armored Cavalry Regiment, W2 Company was deployed to help the Americans defend the base from enemy attack. In two days the New Zealanders and Americans together achieved 20 enemy killed, with 4 killed by W2 Company. Numerous weapons were captured.
On 15 May, W2 Company and 3 Platoon from V4 Company were deployed to Dat Do to help 9 RAR reestablish control of the area. The remainder of V4 Company stayed at Nui Dat base conducting local patrols with 4 RAR. 9 RAR and W2 Company cordoned off the village trapping a company-sized enemy force. Both RNZIR companies conducted a sweep of the inner cordon without incident. 1 ATF forces maintained the cordon until 19 May.

6 RAR/NZ (ANZAC) May 1969 – May 1970

On 19 May, 4 RAR was replaced by 6 RAR and the two RNZIR rifle companies with their Assault pioneers and mortar teams merged with A, B and D Companies of 6 RAR to became 6 RAR/NZ, once again with an Australian commander and a New Zealander 2IC. The main focus of 6 RAR/NZ was the "Pacification" program.
After the new battalion's shakedown operation, Operation Hunter, 6 RAR/NZ carried out its first operation in this program from 30 May when it launched Operation Lavarack. This operation involved the establishment of a number of fire support bases to the north of the 1 ATF base, from where company sized patrols were deployed to specific areas to conduct ambushes and searches. The purpose was to establish enemy movement patterns, particularly those by supply groups, such as the 84 Rear Services Group, which could lead to the location of the main force units. All five rifle companies were deployed with A Company in the south, B Company in the west, V4 Company in the northwest, D Company in the northeast, and W2 Company in the centre north of a Fire support base. Contacts were made by all companies on the first few days leading to the discovery that the 33rd NVA Regiment had moved into the area, a fact unknown to 1 ATF Intelligence. On 5 June, one member of W2 Company was killed on approach to an enemy bunker thought to have been destroyed in an immediately prior attack. Despite supporting mortar and artillery fire, the New Zealanders were trapped for four hours and could not be rescued by APC due to difficult terrain. With the additional assistance of attack helicopters the enemy withdrew and W2 Company moved in to clear the bunker system the following morning. The enemy were revealed to be the VC D440 Battalion, approximately 100 strong.
On 6 June three companies from 1/33rd VC Regiment with elements from VC D440 Battalion, the Binh Ba Guerilla Squad, the Ngãi Giao Guerrilla Squad, and the Chau Duc District Company attacked the village of Binh Ba. 1 ATF Command deployed the Task Force Ready Reaction Force which consisted of D Company 5 RAR, 1 Troop B Squadron 1st Armoured Regiment, and 3 Troop B Squadron 3 Cavalry Regiment under operational control of 6 RAR/NZ. South Vietnamese Regional Forces were deployed in blocking positions. Intense door-to-door fighting took place in order to clear the village and it became apparent that additional NVA forces were in the area. B Company 5 RAR and additional APCs and tanks were sent as reinforcements and the clearing of the village was passed to 5 RAR as Operation Hammer. The Communist forces were driven out by 8 June but the village of Binh Ba was all but destroyed.
Also on 6 June the 1 ATF base at Nui Dat was attacked with rockets and mortars and later in the day 9 RAR came under heavy mortar fire at their Fire support base southeast of Dat Do. The 1 ATF base was again mortared on 7 June. A contact on 11 June by B Company 6 RAR revealed the enemy they had engaged to be 74 NVA Artillery Regiment, those whom were responsible for the rocket attacks on Nui Dat and the FSB. On 12 June, a sentry from V4 Company observed 200 NVA soldiers carrying approximately 50 wounded on litters emerge from the bush into an open area. This was reported to Battalion headquarters. It was thought these were the same forces that A and B Companies had had multiple contacts with earlier in the week. V4 Company was ordered to observe while gunships were called in. However, the element of surprise was lost when the Battalion's support helicopter arrived first, alerting the enemy and causing them to scatter. V4 Company opened up on the group with all weapons brought to bear but were too far to cause any effect. Subsequent helicopter gunships and artillery fire caught some of the fleeing troops but most managed to escape. On 17 June, V4 Company located a large enemy camp with bunkers and caches and was fired on by heavy small arms and RPGs resulting in one New Zealander being killed. All companies continued to make contacts and on 20 June, after three days laying in wait in an ambush position, D Company sighted a group of 60 NVA retreating with wounded. The ambush was sprung and a third of the group was killed. The group was later identified as 1st Battalion, 274th VC Regiment whom were on their way to a hospital facility in the Mây Tào Mountains. On 22 June, 6 RAR's Anti-tank platoon, which had been operating as a Tracker team and as a fourth rifle company under D Company, joined up with V4 Company north of the village of Xa Binh Gia. On the same day one section of W2 Company encountered enemy bunkers and were fired upon by small arms and RPGs by an estimated company-strength force. With artillery support called in the New Zealanders withdrew with three wounded in the engagement.
Operation Lavarack ended on 1 July. The operation proved to be very successful for 1 ATF and 6 RAR/NZ as a whole was involved in some 85 contacts with VC and NVA forces during this time, resulting in over 102 enemy killed and at least 22 wounded. New Zealand casualties were two killed with seven wounded. Australian casualties were one killed and 23 wounded. The NVA and VC Main Force units were severely weakened as a result and D440 Battalion was disbanded with the remainder transferred into D445 Battalion.
With the rest of the battalion remaining at the base, V4 company and B Company together with a team of Tunnel Rats from 1 Field Squadron, next conducted a small operation between 5–10 July, Operation Waiouru, with no contacts.
By this stage of the war, Australian and New Zealand casualties continued to be mostly from mines that the VC had pulled from the Australian barrier minefield and re-laid or had booby trapped. 9 RAR had suffered heavy casualties from mine detonations in a five-week mine clearing operation between 8 May and 15 June. 5 RAR continued mine clearing in the same region from 15 June to 15 July, also suffering heavy casualties from mines. Beginning in July 1969 the Australian engineers devised a more effective solution for sweeping the mines from the barrier minefield, by towing steel rollers behind APCs.
The deadliest Operation
6 RAR/NZ next undertook Operation Mundingburra in the Long Hai Hills on 15 July 1969. This operation would prove to be the single most deadly operation for 6 RAR/NZ. 6 RAR's anti-tank platoon and a team of engineers from 1 Field Squadron, accompanied the Australian and New Zealand platoons. The operation had three objectives: disrupt enemy infiltration into the villages, maintain regular checkpoints on the main access routes between the villages, visit local hamlets and offer medical services to those villagers who might need it. A Company deployed by helicopter to the east of Route 44 in an area colloquially known as "The Light Green" B Company deployed by APC east of Xuyen Moc. V4 Company deployed to the area of the Dinh Co Monastery, west of Route 44. D company deployed east of the Long Hai Hills. W2 Company deployed to Route 44 to provide security operations along the route. All platoons conducted mine clearing and ambushing tasks. On 18 July, 6 Platoon from B Company discovered an occupied camp. In the early morning B Company attacked the camp, killing four VC and recovering documents, with five Australians wounded. The enemy were discovered to be C3 Company, D445 Battalion. In the first five days the Battalion made numerous contacts resulted in over a dozen enemy killed and a steady supply of food and ammunition caches recovered. On 21 July two M16 mines were tripped by two members of A company, the second during the medical evacuation of the wounded from the first detonation. The incident resulted in two Australians killed and 24 wounded. On 23 July, while V4 Company was in the process of clearing the Dinh Co Monastery for use by the locals, a mine discovered by the engineers was detonated killing two Australian sappers and wounding one other. A few hours later one member of W2 Company was killed with five others wounded, two of whom died of their wounds shortly thereafter, from a mine detonation near the hamlet of Ap Lo Gom. On 2 August one member from V4 Company was killed by a booby trap with five others wounded while unloading a truck at the South Vietnamese Regional Force outpost at Lo Gom. The following day 6 RAR lost one of their Assault pioneers and two others were seriously wounded in a mine detonation. On 12 August an RNZE Assault pioneer with W2 Company was killed and three others wounded, with one dying of wounds three months later, in a mine explosion whilst clearing mines from an area surrounding the school at the hamlet of Phuoc Loi. After 31 days the operation ended on 14 August. 6 RAR/NZ's casualties were 11 killed and 54 wounded Enemy killed numbered 22 with 4 wounded and 2 captured. The incident with the Australians on 21 July would be the major inspiration for the 1983 pop song I Was Only 19 by the Australian band Redgum.
On 18 August 1969, the battalion conducted a ceremony on the site of the Battle of Long Tan to dedicate a memorial to the engagement in which the 161st Battery, Royal New Zealand Artillery played a major role in 1966. All five rifle companies from 6 RAR/NZ deployed to sweep the area first for any possible enemy presence and once cleared the monument was airlifted in by helicopter and erected by the Assault pioneers.
From 26 to 28 August, V4 Company deployed into the area of the Courtenay rubber plantation for a reconnaissance-in-force on Operation Tekapo. V4 Company saw two contacts and a large cache of building equipment was recovered with no casualties.
With B Company at The Horseshoe, the remainder of 6 RAR/NZ next conducted Operation Burnham which was a land clearing operation with the "Jungle Eaters" of the U.S 60th Land Clearing Company beginning on 29 August. The operation started with V4 Company establishing and operating out of a fire support base and providing security for the U.S bulldozers. W2 Company was tasked to clear ground in front of the American engineers while A and D Companies provided security to the south and west. During patrolling on 15 September V4 Company discovered an enemy defensive position consisting of 67 bunkers, 130 fighting trenches, 27 trenched shelters, 12 kitchens and a lecture area. Cooking equipment and ammunition were recovered and the position was destroyed. W2 Company had a close call on the evening of 17 September when nearby Royal Thai Army artillery accidentally shelled W2 Company's position with air burst White phosphorus munitions and then later that night again with 155mm M198 howitzer illumination rounds. On 25 September, V4 Company engaged in a firefight with 12 NVA Regulars, killing four, one of whom was identified as a senior officer of 74th NVA Artillery Regiment. During a patrol on 26 September, two members of W2 Company were wounded by enemy gunfire when they discovered and attempted to sweep an enemy bunker. 6 RAR/NZ was relieved by 9 RAR and flown back to Nui Dat on 30 September.
6 RAR/NZ commenced Operation Ross on 13 October and V4 Company joined on the 15th to provide security for the Fire support base established in "The Long Green." 6 RAR/NZ was tasked with harassing D445 Battalion and other VC elements in the area. After numerous contacts, and with one of V4 Company wounded in a contact on 19 October, the New Zealanders were relieved on 24 October leaving the Australian Companies of 6 RAR to continue the operation.
On 28 October, V4 Company was despatched to The Horseshoe in Operation with the ARVN where they were to train ARVN 4/52 Battalion soldiers and have them work alongside them.
Whisky 2 was replaced by Whisky 3 on 14 November 1969. By the end of their tour, Whisky 2 had suffered seven killed and 26 wounded. During this new rotation a mortar section and Assault pioneer section were added.
On 24 November, whilst on patrol with the ARVN near The Horseshoe, V4 Company suffered casualties from a command detonated mined resulting in two New Zealanders killed and two New Zealanders wounded, with a Vietnamese interpreter and two ARVN soldiers also wounded. On the same day the new Whisky Company joined 6 RAR for their first operation in the ongoing Operation Ross. V4 Company returned to Nui Dat on 28 November and 6 RAR with W3 Company returned 30 November upon the conclusion of Operation Ross.
K76A Hospital: Catastrophic defeat for the Enemy
Operation Marsden was conducted in the Mây Tào Mountains where the VC 5th Division was headquartered. By mid 1969 the Ba Long Province Unit had replaced the 84 Rear Services Group in providing logistics functions for the communist forces in the area and assumed administrative control of the VC 274th and 275th Regiments as well as the local Viet Cong guerilla forces in Ba Long, Xuan Loc, Dinh Quan, Xuyen Moc, Dat Do, and Chau Duc. The area was also the location of the K76A Hospital which Intelligence had learned was the principal provider of medical services for the regional VC and NVA forces. The Mây Tào mountains had never before been successfully penetrated by allied forces. All five infantry companies, including their mortar teams and Assault pioneers, from 6 RAR/NZ were deployed on 2 December. 4/52 ARVN Battalion was deployed with V4 Company. A Company scaled the mountains, having to make their way through a 200-meter-wide minefield of improvised mines made from undetonated U.S Air Force Cluster bombs. On 8 December, D Company located the first major stores dump in a cave at the south of the mountains. It contained approximately 2,500 anti-personnel grenades, 22 anti-tank mines, 22 boxes of anti-watercraft mines and a large quantity of weapons, equipment and explosives. On the same day, B Company, on the north side of the mountain, found the first signs of the hospitals. The following day they discovered a bunker system of 12 bunkers identified as part of K76A Hospital. On 11 December V4 Company, operating in the south-east, located 17 large bunkers large enough to take up to 100 patients and identified it as also part of K76A. By this time all companies were discovering enemy signs and having contacts. On the same day W3 Company, which was patrolling north-east of the Song Rai River, located a large enemy camp with 25-28 VC and at first light the following day attacked the group with one VC killed while the remainder escaped. The group was identified as belonging to Ba Long Rear Services Group and the Ba Long Procurement Section. A Company successfully scaled the western side of the mountain and were able to establish a fire support base on the summit. On 14 December 4/52 ARVN left the operation. On 16 and 17 December D Company located the K76A pharmacy, dental post, and orderly room. There they recovered a huge supply of medical drugs. On 19 December, V4 Company discovered the major part of the hospital, a 200-bed complex complete with underground pharmacy, operating pits and convalescing wards. An enormous cache of medical supplies, food, tools, and equipment were found at the hospital and a large weapons cache was discovered nearby. Over the next week all rifle companies conducted day and night search and destroy missions in their areas, spending Christmas 1969 in the field. All companies returning to Nui Dat by 28 December. Four Australians were killed with nine wounded during the operation. There were no New Zealand casualties. Enemy killed numbered 22 with 5 wounded and 21 prisoners, 14 of whom had been patients of the K76A Hospital. Between D Company's and V4 Company's finds, approximately 1.5 tonnes of pharmaceuticals had been captured, possibly the largest amount ever seized in the war by allied forces. The discovery of the hospital would prove to be a catastrophic defeat for the Communist forces in the area.
On 30 December, W3 Company were redeployed on a short search and destroy mission with B and D Companies from 6 RAR in Operation Bluewater, into an area 12 km north of The Horseshoe where D445 Battalion was thought to be present. There were no contacts and W3 Company returned to Nui Dat again on New Years Day 1970.
The first operation for 1970 by 6 RAR/NZ was Operation Napier which commenced on 10 January, to cordon and search the village of Ngãi Giao and then conduct reconnaissance and ambush operations in the area. Along with their Assault pioneers, W3 and V4 Companies conducted daily patrols around the area of the village with almost daily contacts with the VC. V4 Company's contacts included contact with the Ngãi Giao Guerilla Squad. On 13 January V4 Company moved to a new area, conducting ambushing and patrolling with great success including capturing key local Communist political members.
On 15 January, W3 Company's mortar section was deployed with B Company, 6 RAR in Operation Matilda. With 1st Armoured Regiment and 3rd Cavalry, B company and the New Zealand mortar section conducted a sweeping action from the coast to the mountains and then across to Nui Dat in an effort to drive the enemy into 5 RAR who were sweeping from north-east. The operation resulted in a number of contacts for 5 RAR. The W3 mortar team returned to Nui Dat 26 January.
Continuing in Operation Napier, from 23 January the Assault pioneer platoons from 6 RAR were put under the command of W3 Company and added to their patrols. From 24 January W3 Company was making daily contacts with the VC. The company's success was marred when on 30 January two members of the company were wounded in an ambush with one New Zealander dying of wounds six weeks later. W3 Company returned to Nui Dat on 12 February having killed 17 VC with many more wounded and as many captured. V4 Company returned to Nui Dat a week later, on 20 February.
On 15 February 1970, W3 Company and their mortar team, was despatched to The Horseshoe while the rest of the battalion prepared for Operation Gisborne. A company from the 5th Cavalry Regiment of the ARVN 18th Division joined W Company at The Horseshoe and underwent training, eventually going out on night patrols with the New Zealanders in March. Duties at the Horseshoe involved one platoon patrolling and ambushing, the second platoon as base defense, and the third platoon providing security for the engineers clearing the barrier minefield. Also in February a new 7 RAR arrived to replace 5 RAR in their final tour.
Operation Gisborne was launched as a follow up of events that occurred in February during Operation Hammersley in which 8 RAR had discovered the headquarters of D445 VC Battalion in the Minh Dam Secret Zone while providing security for a land clearing operation in the Long Hai Hills. 8 RAR had suffered heavy casualties in the operation and were unable to pursue the retreating D445 Battalion which were forced out of the Minh Dam Secret Zone to the area of Dat Do. Operation Gisborne was therefore launched to search and destroy D445 Battalion. Less W3 Company, 6 RAR/NZ commenced Gisborne on 28 February. On the same day A Company, 6 RAR/NZ discovered the relocated headquarters of D445 Battalion and a company from D440 Battalion. The enemy fled during the night following artillery barrages. The evacuated bunker systems were found the next day by A Company and V4 Company. The enemy withdrew to the south-east. On 3 March 8 RAR was deployed on Operation Hamilton in support of Gisborne. On 8 March D Company, 6 RAR/NZ was involved in a clash with elements of D445 Battalion in "The Long Green", resulting in three Australians killed and six wounded. Operation Gisborne ended on 10 March with no New Zealand casualties. 8 RAR continued on with Hamilton until 24 March.
On 18 March, V4 Company embarked on Operation Waipounamu, an independent Search and destroy mission into the Nui Dinh Hills to search for the C41 Chau Duc Company. On the second day of the operation two members of 2 Platoon were injured in a command detonated mine and evacuated by helicopter. Shortly thereafter 3 Platoon was ambushed by a well-concealed and strongly defended VC camp, later discovered to have been the size of two companies. The lead scout was killed instantly in a command detonated claymore mine which initiated the ambush. 3 Platoon was immediately hit with RPGs and machine gun fire, wounding four of the five New Zealanders of the lead section. The two M60 machine gunners of the second section held the VC back but the New Zealanders were pinned down. As artillery support was not feasible due to unsuitable topography, U.S helicopter gunships were instead called in to strafe the enemy bunker. As a result, the VC retreated.
"The biggest intelligence coup of the war"
6 RAR/NZ, less W3 Company commenced Operation Townsville on 23 March on what would become a four-week search and destroy mission in the north-eastern regions of Phuoc Tuy province. This would also be 6 RAR's and Victor 4's final operation.
The following day, after the ARVN troops had spent a month at The Horseshoe with W3 Company, Operation Raven began to move the ARVN troops back to their home base in Xuan Loc.
While the rest of W3 Company escorted the ARVN troops home, W3 Company's mortar section was deployed on operations with 3rd Cavalry Regiment in and around the Courtenay rubber plantation and remained with them until the end of April.
W3 Company arrived with their ARVN colleagues at Xuan Loc on 29 March. W3 Company returned to The Horseshoe the following day.
Operation Townsville resulted in a huge coup for the ANZAC forces when on 8 April V4 Company encountered an enemy camp which after a short firefight and the enemy fleeing, turned out to be the headquarters of the Ba Long Province Unit. B Company was sent to chase them and made contact resulting in three VC dead, and two wounded. Amongst the documents captured were the operational signals codes and one-time cipher pads used by the VC headquarters. As a result, senior U.S commanders including General CW Abrams, Commander USMACV were alleged to have referred to it as "the biggest intelligence coup of the war." On 15 April W3 Company was relieved at The Horseshoe by 7 RAR and joined the rest of 6 RAR/NZ on Townsville. V4 Company suffered their last casualty during this operation, losing one of their officers during a contact with the VC on 17 April. Operation Townsville concluded 24 April, with 6 RAR and V4 Company both ceasing operations in preparation for their departures from Vietnam.
On 4 May, W3 Company - together with their mortar section which had just returned from operations with 3rd Cavalry - and an Australian Engineer Splinter Team were deployed to Long Sơn Island to destroy VC positions on the island while protecting the engineers from 17th Construction Squadron who were building water sources for the commune of Long Son. With 6 RAR making preparations to leave, W3 Company was put directly under the command of HQ 1 ATF. Patrols escorted the engineers to and from the village each morning and when they finished their work in the evening. On 10 May one of the W3 mortar crew was wounded when the Fire support base was fired on. The W3 mortar section remained at the fire base until the end of May.
On 5 May 1970, Victor 4 was replaced by Victor 5. By the end of their tour Victor 4 had suffered six killed, one dying from an illness while on active duty, and 14 wounded.

2 RAR/NZ (ANZAC) May 1970 – May 1971

2 RAR began arriving from 28 April 1970 and between 10–25 May, 2 RAR and Victor 5 conducted operational training and attended briefings in preparation for operations while W3 Company continued operations on Long Son Island.
On 15 May, 2 RAR fully replaced 6 RAR and with Whisky 3 and Victor 5 became for the second time 2 RAR/NZ. This tour continued to be focused mainly upon the "Pacification" program which 1 ATF had adopted as its first priority in April, 1969.
W3 Company, less 2 Platoon which remained with the W3 mortar section on Long Song Island, was deployed on 15 May to an area west of the Nui Dinh Hills on Operation Ashfield. The Company established a small fire base and began reconnaissance and ambush operations. Support was also provided from the mortar team at the fire base on Long Son Island. The Company made a number of contacts and on 22 May one member of W3 Company was wounded in an attack from a bunker system containing 15–20 VC. One VC was killed and a number of weapons, equipment and documents were recovered, identifying the members as being from C21 Chau Duc Company.
Following a familiarization operation for 2 RAR and V5 Company, W3 Company returned from Operation Ashfield to join 2RAR/NZ's first battalion operation: Operation Capricorn on 26 May.
On 28 May 1970 it was announced by 1 ATF Command that the barrier minefield had been cleared of all mines.
During a patrol on 29 May, a tripped booby trap resulted in one New Zealander from W3 Company killed and one other wounded. Only a few hours later a pressure mine detonation resulted in two Australians from C Company killed and three others wounded – the first casualties of the new battalion. Meanwhile, W3 Company's detached platoon and mortar team returned from Long Son Island to Nui Dat on 30 May. On 2 June, an officer from W3 Company was wounded from shrapnel from an RPG when the platoon discovered and fired on a VC camp. 2 RAR/NZ ended Operation Capricorn on 9 June.
Operation Cung Chung followed immediately after beginning on 12 June, which was a Task Force reconnaissance-in-force involving all battalions with the purpose of denying the Communist forces access to villages and to use their supply routes. 2RAR/NZ was positioned along Route 15, 8 RAR was positioned along Route 2, and 7 RAR held positions along Routes 23 and 44. All companies conducted ambushing, security operations around the villages, and reconnaissance actions in search of enemy camps. W3 Company remained at Nui Dat providing base security. During a reconnaissance of an enemy camp on 18 June, one member of V5 Company was killed from a command detonated 155mm howitzer shell with another dying of wounds shortly after. Two others were also wounded from the blast and three others were wounded by enemy fire during the ensuing firefight.
2 RAR and V5 Company underwent refresher training from 30 June until 13 July. While that was occurring W3 Company was temporarily placed under operational control of 8th Battalion, Royal Australian Regiment who were engaged in Operation Petrie, the mission of which was to destroy VC D440 Battalion. W3 Company's involvement was to support 8 RAR's operations north of Niu Dat, under Operation Quartermile. The operation was downgraded to supplying security to the villages of Bình Ba and Ap Suoi Nghe along Route 2.
From 13 July 2RAR/NZ commenced Operation Nathan. W3 company went north to the fire base established at Le Loi, alongside Route 2 in which 8 RAR and 161 Bty RNZA were operating. W3 Company commenced search and destroy operations in the Binh Ba rubber plantation. On 21 July while approaching a VC camp, W3 Company was fired on by an RPG, wounding three men. On 26 July, V5 Company, who were operating in the Nui Toc Tien mountains, were pursuing a retreating enemy into caves in the mountains. The VC had mined the area around the caves, several of which were set off, wounding nine members of V5 Company and one member of the New Zealand Special Air Service who was acting as a scout for the platoon. W3 Company remained at the fire base at Le Loi until 2 August when it was relieved by 8 RAR.
Operation Cung Chung II was launched 3 August involving 7 RAR, 8 RAR and 2 RAR/NZ to ambush VC supply routes. W3 Company, less their mortar team, departed the operation on 10 August returning to Nui Dat from 14–22 August to provide security for the base.
The W3 mortar team returned to Nui Dat on 29 August and at the request of 3rd Cavalry were deployed the next day with them and a troop of the Australian tanks, engineers from 1 Field Squadron, and 1 ATF HQ's Defence & Employment Platoon on Operation Massey Harris, a food denial program conducted in the area of Bình Châu along the western border of Phuoc Tuy and Binh Tuy. It was known that this was the area that 84 Rear Services Group were growing crops. One of the APCs struck a booby trapped mine injuring 12 Australians, eight of them D&E Platoon members whom were riding in the APC. A Kit Carson Scout was killed in the blast, the only fatality.
W3 Company again came under operational control of 8 RAR and was redeployed from Nui Dat onto Operation Cung Chung II and from 31 August provided security for Australian land clearing teams. A number of contacts resulted in important information about the VC units operating in the area and in particular a contact by W3 Company on 20 September resulted in important documents being captured revealing the effectiveness of the recent ambushes and details of supply line changes to D445 VC Battalion and C41 Châu Đức District Company. Operation Cung Chung II concluded 10 September and 2 RAR/NZ, less W3 Company, returned to Nui Dat for a further period of rest and retraining.
W3 Company's mortar teams completed Operation Massey Harris and on 18 September rejoined W3 Company for their last two days of operations with 8 RAR.
With W3 Company back with the ANZAC Battalion, 2 RAR/NZ and 7 RAR were redeployed on Operation Cung Chung III on 21 September. W3 Company remained in the field until 25 September, and returned to Nui Dat to provide base security. On 28 September an ambush laid by V5 Company resulted in eight VC killed and one captured. Intelligence gained from the prisoner led to the discovery of the location of C41 Châu Đức District Company headquarters.
On 8 October W3 Company was replaced as the base security force by V5 Company and sent to assist C Company, 2 RAR who had found a large enemy camp and had come out of a firefight with casualties. On 10 October a friendly fire incident on a patrol resulted in four members of W3 Company being wounded with one dying of wounds the next day. W3 Company spent their last month patrolling north of the Nui Dinh Hills, finishing operations on 31 October.
A patrol undertaken by V5 Company on 31 October resulted in one New Zealander killed and two others wounded. The report of this incident was revealed some 30 years later to have been a fabrication and in fact the incident had been a friendly fire incident, the facts of which had been suppressed by the platoon hierarchy and company commanders.
Reduction of U.S and Allied Forces
Continuing with President Nixon's "Vietnamization" program, during 1970 the United States had been steadily reducing its forces in Vietnam including those that operated in the Phuoc Tuy-Long Khanh regions. Consequently, the U.S artillery units that supported 1 ATF were withdrawn from South Vietnam in November. The Australian and New Zealand governments also took measures to reduce troop strength. After three tours Whisky 3 Company was withdrawn in November and was not replaced. By the end of their tour Whisky 3 suffered three killed and 13 wounded. Thereafter, Victor 5 was the only RNZIR infantry company in theatre for the remainder of 2 RAR/NZ's tour. Also in November, 8 RAR returned to Australia and was not replaced, reducing 1 ATF to only two battalions: 2 RAR/NZ and 7 RAR. Further U.S reductions saw the 2nd Brigade 25th Infantry Division which operated north of the Phuoc Tuy-Long Khanh borders begin its departure in December 1970, withdrawing entirely by May 1971. The U.S 11th Armored Cavalry Regiment also began to withdraw from February 1971.
Between December 1970 through to 21 February 1971, 2 RAR/NZ and one troop from 1st Armoured Regiment always under operational control of 2 RAR/NZ conducted night ambushes around Hoa Long, returning each day to Nui Dat.
To offset the withdrawal of the second New Zealand infantry company, in January the New Zealand government committed the 1st New Zealand Army Training Team to Vietnam. 1 NZATTV was made up of advisors from all branches of service, a number of whom had served in the RNZIR companies and the RNZA battery in Vietnam. The team assisted an American training team in Chi Lang to train South Vietnamese platoon commanders in weapons and tactics.
From 1 February 1971 Operation Phoi Hop began which was to begin handing over 7 RAR's area of operations to the South Vietnamese forces. 7 RAR's involvement ended 21 February in preparation for their return to Australia, with 2 RAR/NZ relieving 7 RAR. At the same time, the Australian and New Zealand SAS Platoons were withdrawn and on 25 February a new 3 RAR arrived from Australia to relieve 7 RAR. On 26 February 3 RAR was deployed to the Horseshoe to commence in-theatre training. 2 RAR/NZ supplied a rifle company to 3 RAR to assist.
Even though 2 RAR/NZ was reduced to three rifle companies, full-scale operations nevertheless continued through March with the 2 RAR/NZ companies conducting ambushes and patrolling with the Australian APCs and tanks from several Fire support bases. The battalion made several contacts with elements of VC D445 Battalion for a total of 30 VC killed. On 10 March while V5 Company was ambushing a track a contact occurred and in the response a Claymore mine accidentally detonated from a fire caused by M60 tracer ammunition, killing the platoon commander and wounding another.
3 RAR's training was cut short when 1 ATF Intelligence confirmed that VC D445 Battalion was moving in to disrupt the handover actions being done by the task force as part of the overarching "Vietnamization" program. 3 RAR was deployed to intercept D445 Battalion. Several contacts occurred and a bunker system was found and destroyed. To further 3 RAR's successes, A Company 2 RAR/NZ was placed under operational control of 3 RAR on 26 March, further reducing 2 RAR/NZ to just one Australian rifle company and Victor 5 Company. 3 RAR were then deployed on Operation Briar Patch I to directly search for and destroy D445 Battalion while the remainder of 2 RAR/NZ continued on Operation Phoi Hop. After 3 RAR was involved in heavy fighting on 31 March V5 Company relieved C Company, 3 RAR. The operations by 2 RAR/NZ and 3 RAR to track down D445 VC Battalion continued throughout April but the VC managed to escape and withdraw into Long Khanh Province. Victor 5 Company returned to Nui Dat at the end of April to make preparations to leave South Vietnam and return to Singapore. Operation Phoi Hop concluded 2 May. Victor 5 ended their tour in South Vietnam having suffered 4 killed and 27 wounded.

4 RAR/NZ (ANZAC) May 1971 – December 1971

On 6 May 1971 Victor 5 was replaced by Victor 6 and after familiarization training with 3rd Cavalry commenced their first operation on 15 May in the area of the Courtenay rubber plantation, while the outgoing 2 RAR conducted short reconnaissance and ambush operations in around Nui Dat until end of their operations on 20 May. On 22 May 2 RAR was replaced by 4 RAR. The final and sole New Zealand infantry company was integrated with B, C, and D companies of 4 RAR to become 4 RAR/NZ for the second time, serving until the withdrawal of the Australian and New Zealand combat troops. Unlike previous battalions whom conducted rotational duties as base defence or at The Horseshoe in addition to field operations, 4 RAR/NZ would spend the entirety of their tour on operations in the field with rotations at Nui Dat as the Task Force Ready Reaction Force, and for rest and retraining.
From 3–5 June, the new ANZAC Battalion conducted their shakedown operation, Operation Bhowani Junction, in the area of the Courtenay rubber plantation.
By 1971 Phước Tuy had been largely cleared of local VC forces, who were now increasingly reliant on reinforcements from North Vietnam. As a measure of some success, Route 15 was opened to unescorted traffic. However, the reduction of American and Australian forces did not go unnoticed by the Communists. Intelligence reports had indicated a growing presence of well-trained North Vietnamese Army troops in northern Phước Tuy and the final battles fought by Australians and New Zealanders in Vietnam were against these North Vietnamese Regular forces, following the launch of Operation Overlord on 5 June. 2/8 Battalion from the U.S 1st Air Cavalry Division's 3rd Brigade was brought into the operation and with 4 RAR/NZ and 3rd Cavalry placed in a static role of cordoning through ambushing, while 3 RAR with tanks from C Squadron 1st Armoured Regiment were deployed on search-and-destroy actions. 3 RAR became involved in intense fighting against elements of the NVA 33rd Regiment including VC 274th Regiment in the Battle of Long Khánh, sustaining heavy casualties during these engagements, but the battalion successfully hindered their attempts to move south into the province.
Operation Overlord concluded on 14 June to be immediately followed up with Operation Hermit Park, with 3 RAR this time in the static role and 4 RAR/NZ tasked with locating and destroying elements of VC 274th Regiment and C41 Châu Đức Company. This operation would be a significant engagement for Victor 6 Company. B and C Company were deployed to the south west of the province to search for C41 Company while V6 Company was deployed to the north west border where the 274th Regiment was thought to be reestablishing itself. On 24 June 1971, while approaching the outskirts of a bunker one member of V6 Company was shot by a sentry, dying of wounds later that night after medevac efforts were hampered. The following day V6 Company moved up to assault the bunker position. A fierce firefight ensued with seven enemy killed with four members of V6 Company wounded. After withdrawing to safety V6 company was briefed for a new assault and in the afternoon five Australian tanks lead the assault on the bunker with V6 Company following behind. Braving heavy fire the combined firepower of the tanks and V6 Company forced the enemy to withdraw by the evening. The position was discovered to have been held by 1st Battalion, VC 274th Regiment, an estimated 40-60 men. Operation Hermit Park concluded 27 July.
From the middle of July, 4 RAR/NZ progressively occupied a large hill overlooking the Courtenay rubber plantation, nicknamed "Courtenay Hill" which was strategic also for the fact that it was located midway between the communist bases in the Hat Dich and in the Mây Tào Mountains. The hill was solid rock and had to be built up with over 100,000 sandbags to provide adequate observation and defense functions. Courtenay Hill became the headquarters and Command Post of 4 RAR/NZ through to October 1971.
On 28 July 3 RAR and 4 RAR, less V6 Company who remained at Nui Dat as the Ready Reaction Force, were immediately deployed on Operation Iron Fox to conduct operations along the Suoi Ca river near the Long Khanh and Phuoc Tuy borders with the purpose of further restricting VC 274th Regiment's efforts to re enter the province.
On 5 August 4 RAR/NZ were deployed on Operation Northward, conducting ambushing and patrolling from Courtenay Hill.
Australian and New Zealand withdrawal
In August 1971 the Australian government had announced that 1 ATF would be withdrawn from South Vietnam before Christmas. The New Zealand government also announced New Zealand's withdrawal. On 29 August the Australian tank regiment fully ceased operations in preparation for its return to Australia.
Operation Northward was hastily concluded on 18 September following further intelligence obtained alerting 1 ATF to the presence of 33rd NVA Regiment in the province. Operation Ivanhoe was immediately launched on 19 September with the purpose to find the NVA 33rd Regiment headquarters and its 3rd Battalion. Unbeknownst to 1 ATF Intelligence was that 2nd Battalion, 33rd Regiment had also entered the province. Between the two battalions, enemy numbers amounted to 1,100 highly trained Regular forces. V6, B, and D Companies of 4 RAR/NZ were deployed on the operation with 3rd Cavalry, 104th Field Battery, and 161st Independent Reconnaissance Flight in support. V6 Company patrolled west of Route 2 while D Company patrolled east of Route 2, and B Company patrolled south, near Binh Ba. 3 RAR was also deployed west of the Song Rai River nearer to the Long Khanh border. On 20 September 33rd NVA Regiment launched a rocket attack on an Australian APC column travelling north on Route 2 that was on its way to the South Vietnamese Regional Force outpost at Cam My village which had been rocketed the previous day. The attacks on the RF base and on the responding Australian APCs were intentionally launched by the NVA to bait the Ready Reaction Force company at Nui Dat to respond whereupon a massive ambush had been laid for the Reaction Force. B Company travelled out from Nui Dat by APC as expected, but by sheer happenstance the Company Commander stopped the Company short of the ambush site and without knowing it went around the Kill zones. On 21 September D Company discovered the bunker system of the same enemy forces that had attacked the RF base and had laid the trap for the Ready Reaction Force, and engaged in fierce fighting against 600 NVA Regulars, but now with no tanks and limited artillery support. The bunker system turned out to be the location of both the 33rd Regiment headquarters and its 2nd Battalion. As the day turned to night fighting continued with 3rd Battalion, 33 Regiment also involved. American airstrikes and Australian artillery held the enemy at bay, saving D Company from being wiped out. After 14 hours of fighting the enemy disengaged. The Battle of Nui Le resulted in five Australians from D Company killed and 30 wounded. Late in the afternoon of the following day D Company were reinforced by V6 Company in anticipation of a follow-up attack, but none came. On 23 September, V6 Company lead the final assault against the bunker, however when they arrived, the enemy had withdrawn. As a result of the battle, the 33rd Regiment withdrew permanently from Phouc Tuy Province. Operation Ivanhoe concluded on 2 October.
With 3 RAR back at Nui Dat preparing to return to Australia, V6 Company's last combat operation was Operation Valiant which together with B Company 4 RAR, involved a sweeping action each side of Route 2 during the move back to Nui Dat from Courtenay Hill. D Company was already back at Nui Dat as the Ready Reaction Force and C Company was airlifted back on 4 October. The move took from 3–6 October and resulted in one contact for V6 Company, which would be the last contact for the battalion and for 1 ATF.
With the battalion's tour cut short, Victor 6's last operation was one of protecting the activities of 1 ATF's withdrawal from South Vietnam during Operation Southward. As the only Australian battalion left, 4 RAR/NZ was reinforced by some U.S elements including artillery while they moved the South Vietnamese forces fully into the Nui Dat base. The majority of 4 RAR/NZ withdrew from Nui Dat to Vũng Tàu on 7 November 1971. The Australians departed on 8 December and the New Zealanders departed on 9 December. D Company, 4 RAR, remained behind until 12 March 1972 in order to provide security to rear details. The last Victor Company would suffer a total of 1 killed and 5 wounded during its tour in South Vietnam.
The very last RNZIR contribution to the Vietnam War was in March 1972, when the second New Zealand Army Training Team arrived at the U.S Dong Ba Thin Base Camp, near Cam Ranh Bay on the south-east coast. Made up of members from various New Zealand branches of service including RNZIR, the team helped train Khmer National Armed Forces personnel in weapons and tactics and first aid. The two New Zealand training teams were withdrawn from Vietnam in December 1972.
Additionally, over the course of the war RNZIR personnel served in administrative roles at the New Zealand HQ V Force in Saigon, in support and logistic roles within the ANZAC Battalions at Nui Dat, and in the 1st Australian Logistics Support Group.

Operations

As part of 1 ATF, New Zealand infantry participated in the following operations:
As part of the newly formed ANZAC Battalion with 2 RAR, New Zealand infantry participated in:
As part of the next rotation of the ANZAC Battalion, with 4 RAR, New Zealand infantry participated in:
With the next ANZAC battalion, formed with 6 RAR, New Zealand infantry was involved in:
As part of 2 RAR/NZ Whisky 3 and Victor 5 Companies were involved in:
As part of 4 RAR/NZ Victor 6 Company was involved in:
RNZIR casualties during the Vietnam War were:
Having been based at Terendak Camp since 1961, 1 RNZIR relocated to Nee Soon Barracks on Singapore in December 1969. In 1971 the 28th Commonwealth Infantry Brigade Group would be disestablished and 1 RNZIR would come under the command of ANZUK Force. In June 1971 1 RNZIR would relocate from Nee Soon to Dieppe Barracks. In 1974 ANZUK Force was disbanded and 1 RNZIR became the Infantry component of the New Zealand Force South East Asia which it would remain a part of until 1989 when 1 RNZIR was redeployed to Linton Camp in New Zealand.

1973 Reorganisation

In 1973, the Regimental Depot in Burnham Camp was predesignated as the 2/1st Battalion, Royal New Zealand Infantry Battalion, creating for the first time since 1948 a second Regular Infantry Battalion in the New Zealand Army. Today, the RNZIR has two Regular Battalions:
An additional battalion, known as the 3/1st Battalion RNZIR, was occasionally formed as a composite battalion from the Territorial Battalions during exercises.
On 17 March 2013 the six TF battalions were amalgamated into three Battalions;
In the first deployment of New Zealand combat troops to a war zone since the Vietnam War, 1 RNZIR contributed a rifle section to provide security for the New Zealand Supply Contingent in Somalia from July 1993. There would be two rotations with the final section departing Somalia in June 1994.

Former Yugoslavia

Alongside troops from Queens Alexandra's Mounted Rifles, 1 RNZIR and 2/ RNZIR would both contribute to the Mechanized Infantry Company Group that formed New Zealand's commitment to the United Nations Protection Force. Serving as part of a British Battalion from 1994, two Company Group rotations would serve in the Former Yugoslavia.

Organisation

In the New Zealand Army, an infantry platoon is commanded by a second lieutenant or a lieutenant with a Platoon Sergeant, a Platoon Signaller and a medic comprising the Platoon Headquarters. The platoon is sub-divided into three sections of between 7–10 soldiers, each commanded by a corporal with a lance corporal as the Section second-in-command. Each section can be sub-divided into two fire-teams, commanded by the Section Commander and 2iC respectively, as well as normal two-man Scout, Rifle and Gun Teams. In recent years the section organisation consists of the two fire team concept, where the section is divided into two fire teams with a Gun Team in each and one commanded by the section corporal and the other section lance corporal with a section marksmen in each team and the leftover riflemen divided equally among the two fire teams. The section corporal is still in overall command and is in contact with the other fire team via radio if the situation changes.
There are three platoons in a rifle company, which is commanded by a major, and three rifle companies within an infantry battalion, which is commanded by a lieutenant colonel. An infantry battalion will also contain an organic Support Company including a signals platoon, mortar platoon, Direct Fire Support Weapons Platoon which includes anti-armor, heavy machine guns and automatic grenade launchers, Reconnaissance Platoon and Sniper cell, and a Logistics Company. The battalion totals around 400 to 500 soldiers depending on retention levels.

Battle honours

Because it is recruited on a nationwide basis and has no specific regional links, the Royal New Zealand Infantry Regiment claims descent from the old New Zealand Regiment and all previous Territorial Infantry Regiments of the New Zealand Army. As a consequence, it is permitted to display a selection of 105 battle honours awarded to ten separate regiments:
