Loss position

View the 6 war patrols

According to a crew member on the HMCS Waskesiu the HMS Nene only participated in picking up survivors while the Canadian frigate dropped the depth charges, after both frigates had picked up an ASDIC signal that the Canadians insisted was a U-boat, that sank the boat.

Attacks on this boat

14 Jun 1943
At 16.05 hours, U-257 in a group of 3 outbound boats with U-600 and U-615 was strafed and attacked with 3 depth charges by a British Whitley aircraft (10 OTU RAF/P, pilot P/O Orr) in the Bay of Biscay. One crewman was wounded. Another Whitley aircraft from the same unit (10 OTU RAF/E, pilot Sgt Manson) exchanged gunfire with this group shortly afterwards, but the aircraft had used up its depth charges in an earlier attack.

General notes on this boat

5 Oct 1942. On 5 October, 1942, while closing on convoy HX-209, U-257 was attacked by an aircraft which dropped 6 bombs. The U-boat suffered such severe damage it had to return to base.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-257 did not suffer any casualties (we know of) until the time of her loss.
