Attacks on this boat

29 Mar 1942
At 14.11 hours, a U-boat was spotted by HMS Fury, escorting the damaged HMS Trinidad off the port bow in the Barents Sea. The destroyer attempted to ram the enemy, but it escaped by diving and was only attacked with three depth charges as the throwers were iced up. For some time it was believed that this attack sank U-585, but was actually against U-378 causing no damage. (Sources: 1977-01-01, Claude Huan)

13 Oct 1943
The boat was attacked by a Fido homing torpedo from an Avenger aircraft but the torpedo missed the boat. (Sources: Blair, vol 2, page 447)

2 recorded attacks on this boat.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-378 did not suffer any casualties (we know of) until the time of her loss.
