General notes on this boat
14 May 1944. On 14 May 1944 U-616 attacked convoy GUS-39, damaging two Allied merchants (G.S. Walden and Fort Fidler), and the Allies began to swamp the area immediately (see page on U-371 for details). Eight American destroyers and aircraft from five squadrons hunted the boat until it was sunk on 17 May.
5 hours later U-960 attacked the US destroyer USS Ellyson off Oran, which had survivors from U-616 on board. Luckily for them, U-960's attack was unsuccessful, and another Swamp operation began, which eventually located and sank U-960 on 19 May.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-616 did not suffer any casualties (we know of) until the time of her loss.
