859th Bombardment Squadron


The 859th Bombardment Squadron is a former United States Army Air Forces unit. it was first activated in October 1942 as the 517th Bombardment Squadron, when the Army Air Forces replaced National Guard observation units that had been mobilized and were performing antisubmarine patrols off the Atlantic coastline. A month after its activation, the squadron was redesignated the 12th Antisubmarine Squadron. In August 1943, the Army Air forces began turning the antisubmarine patrol mission over to the Navy and the squadron moved to California, where, as the 859th Bombardment Squadron, it formed the cadre for the 492d Bombardment Group.
After deploying to England, the 492d entered the strategic bombing campaign against Germany, but in three months of combat, suffered the most severe losses of an Eighth Air Force bomber group. The 492d Group was withdrawn from combat in August 1944, and the 859th moved on paper to replace the 788th Bombardment Squadron, which was engaged in Operation Carpetbagger, dropping agents and supplies behind German lines, primarily in France. As American forces advanced in France, this special operations mission diminished. The squadron moved to Italy, where it performed the same mission in the Balkans and Italy. The squadron was inactivated in Italy in October 1945.

History

Antisubmarine campaign

The squadron was first activated at Atlantic City Airport, New Jersey as the 517th Bombardment Squadron on 18 October 1942, when the 377th Bombardment Group replaced the 59th Observation Group at Fort Dix Army Air Field and assumed its mission, personnel and equipment. It was initially equipped with the Stinson Vigilants, Douglas O-46s and North American O-47s of the 104th Observation Squadron, which it replaced at Atlantic City. but converted to Douglas B-18 Bolos and North American B-25 Mitchells the following year. The squadrons of the 377th Group were at various bases along the coast between Delaware and New Hampshire.
In October 1942, the Army Air Forces organized its antisubmarine forces into the single Army Air Forces Antisubmarine Command, which established the 25th Antisubmarine Wing the following month to control its forces operating over the Atlantic. Its bombardment group headquarters, including the 377th, were inactivated and the squadron, now designated the 12th Antisubmarine Squadron, was assigned directly to the 25th Wing. The squadron moved to Langley Field, Virginia in January 1943. In July 1943, the AAF and Navy reached an agreement to transfer the coastal antisubmarine mission to the Navy. This mission transfer also included an exchange of AAF long-range bombers equipped for antisubmarine warfare for Navy Consolidated B-24 Liberators without such equipment.

Conversion to heavy bomber and training

In September 1943, the squadron moved to Blythe Army Air Base, California, where its personnel were used as the cadre for the 492d Bombardment Group, which was being formed at Alamogordo Army Air Field, New Mexico. It was redesignated the 859th Bombardment Squadron and then, on 1 October, assigned to the 492d Group. In December it joined group headquarters and the other three squadron of the 492d at Alamogordo, where they were conducting Consolidated B-24 Liberator training.
By January 1944, most of the ground echelon of the squadron had been used to form other bomber units. 2d Bombardment Division, which controlled VIII Bomber Command's Liberator units in England, began to form new ground echelons from personnel of bomber units already in England, while the air echelon of the 859th continued training at Alamogordo. The air echelon began to depart Alamogordo on 1 April 1944, following the southern ferry route, while the few remaining members of the ground echelon departed on 11 April, sailing on the on 20 April.

Strategic bomber operations

On 14 April, the ground echelon that had been formed in England arrived at RAF North Pickenham The air echelon began arriving on 18 April. The squadron flew its first combat mission on 11 May 1944, joining the strategic bombing campaign with attacks primarily on targets in central Germany. During the first week in June, the squadron was diverted from strategic targets to support Operation Overlord by attacking airfields and V-1 flying bomb and V-2 rocket launch sites. It bombed coastal defenses in Normandy on D-Day, 6 June 1944, and continued interdiction attacks until the middle of the month. Except for support of Operation Cobra, the breakout at Saint Lo, the squadron then resumed bombardment of strategic targets in Germany. However, during its three months of strategic operations the 492d Group suffered the heaviest losses of any Eighth Air Force group. On 5 August, the decision was made to withdraw the 492d Group from combat. The group's heavy losses had begun with one of the group's earliest missions, an attack on Braunschweig, in which it lost eight Liberators to enemy interceptors. When the 492d Group returned to strategic operation, on 20 June Luftwaffe fighters, primarily Messerschmitt Bf 110s, using air to air rockets shot down fourteen of the 492d Group's B-24s. Heavy losses, this time to fighters from Jagdgeschwader 3, were again suffered on 29 June.

Special operations

The squadron transferred to RAF Harrington on 1 August 1944, where it replaced the 788th Bombardment Squadron, which moved on paper to RAF Rackheath and was assigned to the 467th Bombardment Group there. Although nominally a move without personnel or equipment, some low mission crews and aircraft from the entire 492d Group moved to Harrington and were assigned to the 859th Squadron on arrival. The squadron operated chiefly over southern France with B-24s and a few Douglas C-47 Skytrains, engaging in Operation Carpetbagger missions, dropping agents and supplies behind enemy lines. As the Allies advanced across northern France, and with Operation Dragoon placing Allied forces in southern France, full scale Carpetbagger operations wound down by 16 September. This support for the French Resistance earned the squadron the French Croix de Guerre with Palm. With the drawdown of the Carpetbagger mission, the squadron concentrated on hauling gasoline to advancing mechanized forces in France and Belgium. During its assignment to special operations form England, the squadron flew 179 sorties and delivered 121 "Joes", as the agents were called. It also flew a small number of "Nickling" missions.
Even as the need for guerilla support in France was decreasing, it was increasing in the Mediterranean. On 17 December 1944, the 859th departed England, arriving at its new home, Brindisi Airfield, Italy three days later. The 859th's first sortie out of Brindisi was flown on 29 December 1944. A total of six successful sorties were flown that day into Yugoslavia followed the next day by six sortie attempts to targets in Italy. Weather, a mechanical failure, and a reception failure caused all but two of these to fail. In January 1945, the squadron was attached to the newly-formed 15th Special Group along with the 885th Bombardment Squadron, which had been operating from Brindisi since October 1944. For the most part, the 859th operatied in Yogoslavia, while the 885th operated in Italy. Most supply drops were made in the Zagreb region, where partisans were attacking German forces withdrawing up the Sava River valley. On 20 May 1945, thirteen days after V-E Day, the 859th moved to Gioia del Colle Airfield and from there to Bari Airfield Italy in July 1945 where it remained until October 1945 when it was inactivated.
