831st Bombardment Squadron

The squadron was first activated as the 516th 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. The 516th was initially equipped with the North American O-47s and Curtiss O-52 Owls of the 9th Observation Squadron, but converted to North American B-25 Mitchells the following year.[2][3][4] Although the 516th was located with group headquarters, the other squadrons of the group were at various bases along the coast between Delaware and New Hampshire.[5]

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.[6][7] Its bombardment group headquarters, including the 377th, were inactivated and the squadron, now designated the 11th Antisubmarine Squadron, was assigned directly to the 25th Wing.[2][3] 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.[8]

The squadron was redesignated the 831st Bombardment Squadron on 1 October and moved to Fairmont Army Air Field, where it acted as the cadre for the newly-activated 485th Bombardment Group. It trained with Consolidated B-24 Liberators until March 1944, when it deployed to the Mediterranean Theater of Operations. En route to the theater, on 20 April 1944, 154 members of the Squadron were lost when the Liberty ship SS Paul Hamilton was sunk by an aerial torpedo.[9] The squadron's ground echelon arrived at its base at Venosa Airfield, Italy in April, but when the air echelon arrived in theater, it remained in Tunisia for additional training.[2][10]

The squadron entered combat in May 1944, and primarily flew long range strategic bombing missions against targets in Italy, France, Germany, Austria, Hungary, Romania, and Yugoslavia, bombing marshalling yards, oil refineries, airfields, heavy industry, and other strategic objectives. The squadron was awarded a Distinguished Unit Citation for continuing an attack on an oil refinery near Vienna, Austria on 26 June 1944 despite heavy fighter opposition.[10]

The 831st was occasionally diverted from the strategic campaign to carry out some support and interdiction operations. It struck bridges, harbors, and troop concentrations in August 1944 to aid with Operation Dragoon, the invasion of Southern France. It also hit communications lines and other targets during March and April 1945 to support the advance of the British Eighth Army in northern Italy.[10]

The unit departed Italy in May 1945. In late July, it reassembled at Sioux City Army Air Base, Iowa. The following month, the 485th Group was redesignated as a very heavy group. Because, such groups had only three, rather than four, operational squadrons, the 831st was inactivated on 20 August 1945.[2][10]
