Aircraft attack, aircraft shot down: American Avenger (USN Sqdn VC-9 USN, pilot Lt (jg) W.F. Chamberlain)

The sinking of U-860At 19.22 hours, the boat was located by an Avenger from USS Solomons, which immedately sent reinforcements. Three attacks commenced at 19.46 hours and sank U-860 7 minutes later. The first was a co-ordinated strafing and rocket attack by two Avengers (Lt Cdr H.M. Avery and Ens M.J. Spear) and two Wildcats (Ens T.J. Wadsworth and Ens R.E. McMahon). Wadsworth had to return to the carrier due to an AA hit in a drop tank. A similar attack by McMahon and another Avenger (Lt (jg) D.E. Weigle) then followed. Rockets hits were scored in both attacks, and another Avenger (Lt (jg) W.F. Chamberlain) then dropped two depth charges, covered by a strafing run from Lt Cdr Avery. AA fire and the explosions of the depth charges directly forward of the conning tower damaged the Avenger, which started to burn and ditched into the sea ahead of the boat. U-860 then sank, leaving 30-40 survivors in the water. USS Straub and USS Herzog arrived during the night and rescued 20 German survivors, including the commander, but no trace of the Avenger crew could be found.

3 recorded attacks on this boat.
