Third Battle of Gaza
The Third Battle of Gaza was fought on the night of 1/2 November 1917 between British and Ottoman forces during the Sinai and Palestine Campaign of World War I, and came after the Egyptian Expeditionary Force victory at the Battle of Beersheba had ended the Stalemate in Southern Palestine. The fighting occurred at the beginning of the Southern Palestine Offensive, and together with attacks on Hareira and Sheria on 6–7 November and the continuing Battle of Tel el Khuweilfe which had been launched by General Edmund Allenby on 1 November, it eventually broke the Gaza to Beersheba line defended by the Yildirim Army Group. Despite having held this line since March 1917, the Ottoman Army was forced to evacuate Gaza and Tel el Khuweilfe during the night of 6/7 November. Only Sheria held out for most of the 7 November before it too was captured.
Following British defeats at the First and Second Battles of Gaza in March and April 1917, Lieutenant General Philip Chetwode commanding the EEF's Eastern Force and Kress von Kressenstein's Ottoman Empire force had each adopted a defensive posture and a stalemate had developed in Southern Palestine. Entrenched defences approximately on the lines held at the end of the second battle were strengthened, and both sides undertook regular mounted reconnaissances into the open eastern flank. In late June, Allenby replaced General Archibald Murray as commander of the EEF, which he quickly reorganised. At about the same time, the Ottoman Fourth Army was also restructured. As the stalemate continued in terrible conditions through the summer, reinforcements began to arrive to replace the large number of casualties suffered by the EEF during the previous fighting for Gaza, while several additional divisions also arrived. The Ottoman defenders were also reinforced at this time, and both sides carried out training while manning the front lines and monitoring the open eastern flank. By mid-October, as the Battle of Passchendaele continued on the Western Front, the last of the British reinforcements arrived as Allenby's preparations to commence a campaign of manoeuvre neared completion.
Prior to the Second Battle of Gaza, the town had been developed into a strong modern fortress, with entrenchments, wire entanglements and a glacis on its south and south–eastern edges. A series of field works, mutually supported by artillery, machine guns and rifles, extended from Gaza eastwards to within of Beersheba. Beginning on 27 October, the EEF began a heavy and almost continuous bombardment of Gaza. During this time, the EEF's XXI Corps, holding the Gaza section of the line, had been mostly passive until the night of 1/2 November, when a series determined night-time assaults were mounted against the Gaza defences. Yet these attacks were only partially successful due to the strength of the garrison. The bombardment of Gaza intensified on 6 November and during the night of 6/7 November successful attacks were launched on several trench systems. On the morning of 7 November, Gaza was found to have been evacuated during the night. The Gaza to Beersheba line subsequently collapsed and the Ottoman Seventh and Eighth Armies were forced into retreat. Following several battles during the pursuit, the EEF captured Jerusalem on 9 December 1917.
Background
Gaza was "a strong modern fortress, well entrenched and wired, with good observation and a glacis on its southern and south–eastern face." These defences which were too strong for a daytime attack were extended eastwards by a series of "field works" to from Beersheba. These fortifications were between apart, each mutually supported by fire from artillery, machine guns and rifles.As the troops of the Egyptian Expeditionary Force began to concentrate in preparation for their attacks, they left their camps standing to deceive German and Ottoman aerial reconnaissances. The EEF assumed their opponents thought there were still six infantry divisions in the Gaza area and one in the eastern sector towards Beersheba. However, according to Falls, "here is evidence that the were fairly accurately informed of the British dispositions." On 28 October, they knew the camps at Khan Yunis and Rafa were empty and accurately placed three infantry divisions east of the Wadi Ghuzzee with a fourth, the 10th Division approaching the wadi. They estimated more cavalry at Asluj and Khalasa than was actually there.
The loss of Beersheba on 31 October stunned the Yildirim Army Group commander and staff. The Beersheba garrison withdrew either to the Ottoman defences around Tel es Sheria or northwards to Tel el Khuweilfe to defend the Hebron road. Here a considerable force, including all available reserve units, was deployed in the Kuweilfeh area to stop a threatened advance up the Hebron road to Jerusalem about to the north. According to Powles, " ... the Turkish line had been thrown back on its left, but not broken." The remainder of the Ottoman line stretching westward to the Mediterranean coast continued to be strongly defended, particularly at Hareira, Sharia and Gaza, but the loss of Beersheba had placed EEF mounted units across the Beersheba to Hebron and Jerusalem road, and three Eighth Army infantry battalions were sent by the German General Friedrich Freiherr Kress von Kressenstein to reinforce the Ottoman troops fighting at Khuweilfe to protect the road. They established a new defensive line north of Beersheba, and the 19th Division was sent from the XXII Corps defending Gaza to reinforce the new line at Ebuhof. However, the objective of the EEF advance north of Beersheba was to separate the Ottoman forces supplied by the roads and railways from Ramleh on the maritime plain from those supplied by the motor road from Jerusalem north of Beersheba. Such an advance would also place the EEF infantry corps in a position to begin to "roll up" the Ottoman flank.
Prelude
The EEF controlled the coastal sea lanes, and the Intelligence Service spread rumours about possible sea landings in the rear of Gaza. Ships were seen taking soundings off the coast and a fleet of small boats was located near Deir el Belah. During the late afternoon of 1 November, an embarkation of members of the Egyptian Labour Corps onto motor launches, trawlers and tugs at Deir el Belah was staged as a feint, giving the appearance of continuing into the night. The next morning, two trawlers appeared off the mouth of the Wadi el Hesi north of Gaza. To add to the confusion, between the Battle of Beersheba on 31 October and the main attacks at the Battle of Hareira and Sheria beginning on 6 November, the Ottoman left flank north of Beersheba was being fiercely contested during the Battle of Tel el Khuweilfe for control of the road to Hebron and Jerusalem. According to Wavell, "an assault on a portion of the Gaza defences was to be made by the XXI Corps." The date of this attack, which was primarily a feint, was scheduled for between 24 and 48 hours before the attack on Sheria.Meanwhile, preparations for the main attacks on the Gaza line at Hareira and Sharia, began on 1 November when the 53rd Division, with the Imperial Camel Brigade on the right, advanced northwards to occupy a line to the west without opposition. This placed the infantry in a position from which they could cover the right flank of the proposed attack by the XX Corps on Hareira and Sheria.
Defenders
After the second battle for Gaza in April 1917, Kress von Kressenstein commander of the victorious 3rd, 16th and 53rd Divisionswas reinforced by the 7th and 54th Divisions. The 7th Infantry Division had experienced four months of strategic movement, similar to that of the 54th Division. Having arrived at Jerusalem, in early May the 20th Infantry Regiment began company-level training. After moving to Beersheba where they remained in reserve, they participated in theatre-specific training until late June, when they went into the front line. Training in fortification, reconnaissance, and counter–reconnaissance continued. The 21st Infantry Regiment received similar training, and on 6 August the regimental colours of the 20th and 21st Infantry Regiments were awarded military medals for service in the Gallipoli Campaign. At Beersheba on 28 June, the 7th Infantry Division inactivated the fourth company of each infantry battalion, before activating a machine gun company armed with light machine guns, in every infantry battalion on 10 August. Every Ottoman infantry division in Palestine repeated this reorganisation, with one quarter of their rifle strength being replaced by light machine guns, considerably increasing their fire power and strengthening their offensive and defensive capabilities. Following orders from von Kressenstein commanding the Gaza to Beersheba line defences, assault detachments equivalent to the German Stosstruppen were formed. The 7th Division activated an assault detachment of fifty men on 17 July 1917.The Yildirim Army Group under the command of Field Marshal Erich von Falkenhayn was responsible for the defence of Palestine. On the western flank the Ottoman Eighth Army was composed of the XXII Corps' 3rd and 53rd Divisions defending Gaza and the XX Corps' 26th and 54th Divisions defending the line stretching to the east of Gaza, under the command of von Kressenstein. The defence of Gaza was the responsibility of XXII Corps, which had two divisions in the front line and two in reserve. The XXII Corps' four regiments had 4,500 rifles, which were reinforced by two divisions to bring the total to 8,000 defenders, deployed thus:
- 53rd Division holding from the Mediterranean shore to the eastern side of Gaza,
- 3rd Division on their left, and the
- 7th Division in reserve close behind.
On the left of the XX Corps the Ottoman Seventh Army defended Beersheba, under the command of Fevzi Pasa.
Attackers
The EEF comprised 200,000 men including Arab workers, 46,000 horses, 20,000 camels, more than 15,000 mules and donkeys, and hundreds of artillery pieces. The fighting strength of the EEF was 100,189:- Desert Mounted Corps commanded by Lieutenant General Harry Chauvel had 745 officers, 17,935 other ranks in the Anzac, Australian and Yeomanry Mounted Divisions;
- XX Corps commanded by Lieutenant General Philip Chetwode had 1,435 officers, 44,171 other ranks in the 10th, 53rd, 60th and 74th Divisions; and
- XXI Corps commanded by Lieutenant General Edward Bulfin had 1,154 officers and 34,759 other ranks in three infantry divisions. By 30 October there were 35,000 rifles in the XXI Corps deployed to attack Gaza. They were:
Army Wing aircraft were assigned to carry out strategic reconnaissances, to report on Ottoman reserves well behind their lines, to carry out daily photography, and to conduct air raids. Fighter and bombing squadrons were established for these purposes while the Corps Squadrons were attached to the two infantry corps carried out artillery and contact patrols, along with tactical reconnaissance.
Sherifial Forces
In July, Allenby was hopeful that T. E. Lawrence and the Sherifial Arab force could support a September attack by the EEF, recognising that harvests were being collected before that time, and that after the end of September they normally moved to camel-grazing lands in the Syrian desert. He wrote, "They, naturally, won't and can't do much unless I move; and it is not much use their destroying the Turks' communications unless I take immediate advantage of such destruction ... If I bring them into the fight and do not make progress myself, this will also expose them to retaliationwhich to some tribes, such as the Druzes, S. of Damascus, may mean annihilation." The EEF encouraged the Bedouin to defect:Battle
Four EEF infantry brigades of 10,000 rifles attacked four Ottoman regiments of 4,500 rifleswhich were reinforced by two divisions to over 8,000. Both sides suffered heavy losses. The attacks were to be carried out by well-prepared troops, with overwhelming artillery support and six Mark IV tanks. These attacks were designed to keep the Gaza garrison of 8,000 riflemen supported by 116 guns in place after the capture of Beersheba and during preparations for the main EEF attacks on Hareira and Sheria.Preliminary raids on Outpost Hill
On 26 October, units of the 75th Division raided Outpost Hill. Then, just hours after the capture of Beersheba, on 1 November, a second raid by five officers and 220 riflemen of the 3/3rd Gurkhas Rifles was carried out against Outpost Hill. At 03:00, under cover of an intense bombardment, they entered the Ottoman defences on the hill; two Gurkhas were killed and twenty-three wounded. During the fighting, they killed twenty-eight Ottoman soldiers and captured sixteen, before returning to their lines. The division was to make another attack during the next night, towards Atawineh Redoubt, on the Gaza to Beersheba road.Bombardment
On 27 October, the XXI Corps artillery began the bombardment of Gaza, which gradually grew more intense with the support of British and French Navy's guns from 29 October. They included the guns on HMS Raglan, the Monitors M15 guns, the M29, the M31, and the M32 with guns, the cruiser Grafton, and the destroyers Staunch and Comet. French vessels included the Requin, Arbalète, Voltigeur, Coutelas, Fauconneau and Hache. There were also two river gunboats Ladybird and Aphis, and three seaplane bombers. This flotilla was in actionalthough not altogether to allow for return to Port Said for refuellinguntil the attack on Gaza was launched. The flotilla was targeted by hostile aircraft, while a shell from an Ottoman shore battery hit the mess deck of the Requin, causing 38 casualties.The land based artillery of Bulfin's XXI Corps' heavy artillery consisted of 68 medium and heavy guns and howitzers, which were directed on to the Ottoman batteries during the battle. In addition two 6-inch guns made a surprise attack on the Ottoman railhead at Beit Hanun at a range of, supported by balloon observation. Between 27 October and the attack on Gaza, 15,000 rounds were fired by the heavy artillery; three hundred rounds were allocated for the destruction of each Ottoman battery which had been located. The anti–battery bombardments between 29–31 October also fired gas shells, which apparently had little or no effect. Together with the corps' three divisional artilleries, the guns produced the heaviest bombardment of World War I outside European theatres. The sixth night's bombardment from onshore and offshore guns produced "an even heavier concentration of fire on a small area than had been put in on the first day of the Battle of the Somme." The six-day bombardment program was arranged "so that the whole of the front of our group is plastered all day and every day."
1/2 November night attacks
The XXI Corps attacks were focused on a stretch of sandhills stretching from Umbrella Hill about south-west of Gaza to the Mediterranean Sea. They were timed for the night because the strength of the Ottoman machine guns in defensive positions made day-time attacks impossible. On the right flank, the final objective of the attack was only behind the Ottoman front line, but on the left it was away.The first phase was the attack at Umbrella Hill by the 1/7th Battalion Scottish Rifles with one company of 1/8th Battalion, Scottish Rifles. The second phase was the capture on a broad front of El Arish Redoubt to the Sea Post on the shore by the 1/4th Battalion, Royal Scots and one company of 1/8th Battalion, Scottish Rifles. The third phase was to be conducted by the 161st Brigade and the 163rd Brigade against Gaza's south-western defences, while the fourth phase by the 162nd Brigade was to capture Gun Hill and Sheikh Hasan behind the front line at Sheikh Ajlin. On 1 and 2 November, the Ottoman 7th and 53rd Divisions continued to defend most of their front line, carrying out locally successful counterattacks.
Phase one: Umbrella Hill
On 1 November, the assault of Umbrella Hilla sand dune south–west of Gaza to the west of the Rafa to Gaza road overlooking the main objectiveswas to begin at 23:00. The defending garrison was "assumed to be about 350 strong". However, at 10:50 a preliminary move into No Man's Land was observed by Ottoman soldiers in Fisher's Orchard, who gave the alarm and began firing machine guns and rifles from the Ottoman trenches on Umbrella Hill. At 23:00, an intense EEF bombardment began enabling a tape to be laid, along which the attacking troops formed up to launch their attack ten minutes later. Under cover of the intense ten-minute bombardment, the 1/7th Battalion, Scottish Rifles with one company of 1/8th Battalion, Scottish Rifles attacked Umbrella Hill. After killing many of the defenders, they quickly captured the hill, three officers, fifty-five Ottoman soldiers, three Lewis guns and numerous bombs. The attackers suffered light casualties; however the sand dune was difficult to defend because the Ottoman trencheswithout revetmentshad virtually disappeared during the previous bombardments. The following Ottoman bombardment of Umbrella Hill caused 103 casualties to the 1/7th Battalion Scottish Rifles during the next twenty-four hours. However, with the hill captured by the 52nd Division, the main attack could begin.Phase two: El Arish redoubt
The second phase began at 03:00 on 2 November when the 156th Brigade of the 52nd Division launched the first attack on the El Arish Redoubt. This attack was aimed at breaking the line of defensive fortifications consisting of three groups of trench complexes and redoubts. These were the El Arish, Rafa, and Cricket redoubts, which were connected by a "series of trench lines several layers thick, and backed by other trenches and strong points" stretching along the seaward defences to the west of Umbrella Hill. The attack on El Arish redoubt was to be supported by two of the six available tanks of the Palestine Tank Detachment's eight tanks.The 1/4th Battalion, Royal Scots assault on El Arish Redoubt was carried out in waves through the Ottoman trenches, during which six Ottoman mines exploded, causing EEF casualties. The Ottoman artillery, which had become active as a result of the first attack, had stopped shortly before the second attack began at 06:00 with an intense, ten-minute bombardment. At 06:30, a heavy Ottoman counterattack drove back the leading company of Royal Scots, causing a number of casualties. A platoon from another company helped rally the remnants of the leading company, which was reinforced by the 1/4th Battalion Royal Scots and 1/8th Battalion Scottish Rifles when the position was consolidated. Two tanks passed through El Arish Redoubt, but shortly afterwards one was abandoned and the other hit, while a third tank moved along the front line rolling out wire from Sea Post on the coast to Beach Post.
Phase three: coastal defences
When the Royal Scots had entered the eastern section of the El Arish Redoubt during the second phase of the attack, the western half was still held by Ottoman defenders. These defences became the objectives of the attacks by the 161st and 163rd Brigades of the 54th Division, supported by four tanksincluding the two which had passed through the El Arish redoubt. On the right of the 163rd Brigade's advance, the 1/5th Battalion, The Suffolk Regiment moved towards the Ottoman trenches following a creeping barrage to attack and over–run the western El Arish trenches during hand–to–hand fighting when the 1/5th Battalion, The Suffolk Regiment suffered light casualties. Although they had captured the third line, part of this captured territory had to be abandoned because it was exposed to hostile fire, so they consolidated their position along the second line. Half of the 1/8th Battalion, Hampshire Regiment attacked Burj Trench while the other half attacked Triangle Trench, although it was not their objective. This caused some confusion, and the 1/4th and 1/5th Battalions, The Norfolk Regiment lost direction in the dust and smoke of the cloudy, hazy night. As a result, only small numbers reached Gibraltar and Crested Rock, from where they were quickly forced to withdraw.On the left, the attacks by the 161st Brigade were similarly weakened by loss of direction when the 1/5th Battalion, The Essex Regiment attacked Rafa Redoubt instead of Zowaiid trench. However, the 1/6th Battalion, The Essex Regiment attacked and captured Beach and Sea Posts before attacking the Rafa Redoubt and trench systems, suffering light casualties. In support, a tank rolled out wire as it drove along the front line from Sea Post to Beach Post. Cricket Redoubt was captured with the help of the tank from Beach Post; although the tank was temporarily disabled in the process. After being repaired, the tank was transporting some engineers' stores to Sheikh Hasan when it was hit and disabled again. Two reserve tanks were ordered forward carrying engineers' storesincluding sandbags which were set on fire by hostile fire.
Phase four: 2 November
On their right, the 1/10th Battalion, London Regiment finished capturing and consolidating the Rafa redoubt, which had only been partly captured by the 1/6th Battalion, The Essex Regiment. Without the assistance of tanks which had been put out of action, this battalion lost contact with the barrage and suffered heavy losses. Nevertheless, they captured Gun Hill and by 06:00 on 2 November they were preparing to attack Sheikh Hasan, which they captured fifteen minutes later along with 182 prisoners.Lion Trench, north-east of Sheikh Hasan, was attacked at 07:30 by the 1/4th Battalion, Northamptonshire Regiment with the objective of clearing a gap through which the Imperial Service Cavalry Brigade could advance. However, 20 minutes after their successful attack, the Northamptonshire without artillery support were almost surrounded and forced to retreat to Sheikh Hasan on the coast. Here a strong counterattack was threatened by two regiments of reinforcements from the Ottoman 7th Division, which were advancing from Deir Sneid to the north and north-east. These Ottoman reinforcements were stopped by accurate shelling by the Corps Heavy Artillery, which fired on a line previously registered and by shelling from the monitors off the coast. A planned repeat of the Lion Trench attack was postponed when the 1/4th Battalion, Northamptonshire Regiment attacked Yunis Trench instead. Although they captured the trench they were driven back by a counterattack. Throughout the remainder of the day, Ottoman heavy batteries shelled Sheikh Hasan, before the batteries were withdrawn during the night to the north-east of Gaza. During the night of 2/3 November, Ottoman troops strengthened their defences on Turtle Hill, facing Sheikh Hasan.
The Third Battle of Gaza was never intended to capture the town, but to keep the garrison in place after the capture of Beersheba. Only the first line of Ottoman trenches had been the objectives of the XXI Corps, which used new infantry tactics, tanks and massed artillery organised in accordance with Western Front standards. Although all objectives had not been won, the operations had forced two regiments of the Ottoman 7th Division reserve to move away from Hareira and Sheria, forward to strengthen the Ottoman defences between Gaza and the sea. According to the British official historian, "The attack on the western defences of Gaza ... had fulfilled the Commander-in-Chief's object." The EEF had also inflicted severe losses on the Ottoman defenders; more than one thousand of whom the EEF buried in the captured trenches. The EEF captured twenty-eight officers, 418 soldiers, twenty-nine machine guns and seven trench mortars. During the fighting, the corps infantry had advanced about on a front, and held their gains against repeated Ottoman counterattacks, although the attempt to create a gap for the Imperial Service Cavalry Brigade to ride through was not successful. The front line defensive system on the south–west side of Gaza had been captured and the infantry occupied a position from which they could threaten "Ali Muntar and the rest of the defences in front of the town." The XXI Corps suffered 350 killed, 350 missing and two thousand wounded during this fighting. Many casualties were blamed on loss of direction and crowding in the captured trenches, which were too shallow.
Air raids
Air raids by the EEF were carried out during the night of 1/2 November, with twelve bombs being dropped on Gaza, and on 3 and 4 November, with air raids over the hills north of Beersheba.Aftermath
3–6 November
During a Khamsin on 3 November while the bombardment of Gaza resumed, the 1/4th Battalion The Essex Regiment attacked and captured Yunis trench at 04:30. However, they were heavily counterattacked and forced to withdraw. The following night, several strong Ottoman counterattacks were made on the 75th Division's position at Sheikh Abbas on the eastern side of Gaza, which were all stopped by machine gun and rifle fire. Meanwhile, the newly won position at Sheikh Hasan on the Ottoman right flank was consolidated.By 5 November 1917, the Ottoman XXII Corps commander in charge of the defence of Gaza, Colonel Refet Bele, was continuing to maintain the "integrity of the Gaza fortress", despite the Gaza garrison's artillery batteries having only about 300 shells left. These batteries had also been suffering from effective counter-battery fire from the EEF Heavy Artillery Groups. Refet had been warned the day before that evacuation may be necessary because of the loss of Beersheba, so plans were prepared for the complete withdrawal from the town during the night of 6/7 November, to a new defensive line on the Wadi Hesi. Falkenhayn commanding Yildirim Army Group realised that the Ottoman forces could not hold the EEF any longer, and he ordered the Eighth and Seventh Armies to withdraw about. The first indications of the withdrawal were seen by EEF aerial reconnaissance, which reported Ottoman hospitals being moved back towards Mejdel. At midnight on 6/7 November, XXI Corps infantry patrols found Gaza had been evacuated by the Ottoman defenders. Until 6 November, German aircraft had rarely been seen over the Gaza lines, but that afternoon two R.E.8s and two B.E.12.as from No. 1 Squadron AFC patrolling and taking photographs were attacked and badly damaged by four Albatros aircraft.
Meanwhile, the heavy EEF bombardment of the Ottoman line in the XXI Corps area at Gaza, which had resumed on 3 November, grew in intensity with the naval guns joining in on 5 and 6 November, and it reached its maximum intensity on 6 November. During the night of 6/7 November the XXI Corps was to launch an attack on Outpost Hill and the Yunus and Belah trench systems, after the main EEF attack on Hareira and Sheria began. This attack on the Wadi esh Sheria was to be "carried out in the most favourable circumstances" against only two Ottoman regiments holding the line.
After launching the successful attack on 6 November against Hareira, the Sheria trenches were also attacked late in the day. These attacks were supported by renewed attacks in the Tel el Khuweilfe area at the eastern extremity of the Ottoman front line. During these attacks, the whole of the Kawukah trenches and part of the Rushdi system which protected Hareira Redoubt, were captured and the Ottoman defenders were forced to withdraw to the Hareira Redoubt. Late in the day a large part of the Sheria defences were also captured after Hareira was bypassed. Only Tel esh Sheria blocked the British advance and Allenby ordered the next day's attacks to continue on Tel esh Sheria, and to be renewed at Gaza. While these attacks took place on 6 November, EEF aircraft bombed Gaza, the main Ottoman positions behind the Kauwukah defences near Um Ameidat, and positions west of Sheria. Three air combats were also fought against three hostile aircraft during the day. Mejdel was also bombed by EEF aircraft. Allenby wrote:
7 November
Occupation of Gaza
The EEF's occupation of Gaza was not strongly resisted and a general advance during the morning of 7 November found the town abandoned. Orders for an attack at 04:50 by the 75th Division on Outpost Hill on the eastern side of Gaza had been issued; these were expanded to include Middlesex Hill and a 54th Division attack on the Belah and Yunis trenches, and Turtle Hill in the coastal sector. However, by 04:35, two battalions each from the 161st and the 162nd Brigades supported by artillery had already advanced to occupy Lion and Tiger Trenches and Sheikh Redwan in the coastal sector to the north-north-west of Gaza. The advance by the 162nd Brigade took them through "the gardens and fields of Gaza to the main road northwards", when patrols sent into the city found it deserted. British artillery had destroyed all the homes, of the 40,000 people who had lived in Gaza before the war. The 54th Division subsequently took up a line stretching from the Jaffa road north of Sheikh Redwan to the Mediterranean sea.When the Ottoman withdrawal became apparent on 7 November, the Royal Flying Corpswhich had been mainly involved in strategic reconnaissance for the 40th Wing, artillery registration and tactical photography for the 5th Wingbegan bombing and machine gun air raids. For seven days, they also made numerous air attacks on Ottoman infrastructure including aerodromes, transport, artillery, and retreating columns.
Mounted breakthrough
The 75th Division with the Imperial Service Cavalry Brigade attached had been ordered to attack Outpost Hill on the eastern side of Gaza, and exploit any potential breakthrough. By 01:00 on 7 November, the 233rd Brigade had already occupied Outpost Hill, and as the brigade moved forward to occupy Green Hill and the Labyrinth at 05:00, they were only opposed by individual riflemen. By 07:00, the 233rd Brigade had patrols on Ali Muntar ridge, while on their right, the 234th Brigade found that the Beer trenches and Road Redoubt defending the Gaza to Beersheba road were still held in strength with machine guns. Throughout the day the Ottoman rearguards in Tank and Atawineh Redoubts continued to fire their artillery at the increasing numbers of EEF troops advancing behind both these Ottoman rearguard's flanks. However, by nightfall, the Beer trenches, and the Road and Tank Redoubts had been captured.The Imperial Service Cavalry Brigade, which had been carrying out patrolling duties based at Tel el Jemmi, was ready to exploit a breakthrough at Gaza, and the Anzac and Australian Mounted Divisions were also prepared for a pursuit through a breach in the line at Sheria. At 09:00, the Imperial Service Cavalry Brigade rode through the ruins of Gaza to reach Beit Hanun at 13:00, where they encountered part of the Gaza garrison defending a strong rearguard position on a ridge south-east of Beit Hanun.
The Hyderabad and Mysore Lancers had advanced through Jebaliya to link with the Glasgow, Lancashire, and Hertfordshire squadrons of the XXI Corps Cavalry Regiment, holding the high ground at Beit Lahl north of Gaza, where they threatened the Ottoman flank. While the Corps Cavalry Regiment captured Beit Lahia, the Hyderabad Lancers advanced at 15:00 to capture the ridge west of Beit Hanun at Sheikh Munam, but the village was strongly defended by numerous Ottoman machine gun detachments. Early in the afternoon, a regiment of the 4th Light Horse Brigade rode across to the north-west to link with the Imperial Service Cavalry Brigade, which had been out of contact with the XX Corps and the Desert Mounted Corps. The 12th Light Horse Regiment met up with the Imperial Service Cavalry Brigade east of Beit Hanun at 14:45. Here they delivered orders for the Imperial Service Cavalry Brigade to attack the Ottoman rearguard on the Wadi el Hesi near Tumra to the north of Beit Hanun.. By 16:55, the rearguard was reported to still be holding Beit Hanun, with concentrations of Ottoman forces at Al Majdal and Beit Duras.
The lancers advanced from the east onto the ridge overlooking Beit Hanun, and despite meeting considerable resistance, captured the position. In the process, they secured twenty-three prisoners, some artillery pieces and a large quantity of ammunition. They also captured the town's water pumping machinery intact, but were forced to withdraw back to Jebaliye for water as the equipment ran on gas made from charcoal, which had to be converted before it could be used.
