Aircraft attack, aircraft shot down: American Avenger (VC-9 USN, pilot Ens G.E. Edwards Jr)

At 12.21 hours, the boat was attacked by the Avenger from USS Solomons about 575 miles south of St. Helena. The aircraft made four attack runs on the boat, but was shot down by AA fire during its last and crashed into the sea, killing the crew of three men. Its contact report resulted in more air attacks from the carrier, which finally sank U-860.

Aircraft attack, aircraft shot down: American Avenger (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 after 7 minutes. The first was a co-ordinated strafing and rocket attack by two Avengers (LtCdr 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 then followed by one Avenger (Lt(jg) D.E. Weigle) and McMahon. Rockets hits were scored in both attacks and another Avenger (Lt(jg) W.F. Chamberlain) now attacked with two depth charges, covered by a strafing run of Avery. AA fire and the explosions of the depth charges directly in front of the conning tower hit the Avenger, which started to burn and ditched into the sea ahead of the boat. U-860 sank after this attack, leaving 30-40 survivors in the water. USS Straub and USS Herzog arrived at the sinking position during the night and managed to pick up 20 German survivors, including the commander, but the crew of three men from the Avenger could not be found.

3 recorded attacks on this boat.
