Heavily damaged on 8 May 1945 in the North Sea west of Bergen, in position 61.32N, 01.53E, by depth charges from a British Catalina aircraft (Sqdn. 210/X). (, March 2002).

Loss position

The normal story of this boat is that she was sunk in the attack here above but that appears to be false.

According to numerous accounts the boat was only damaged and the crew took the boat to Sotre island west of Bergen where the boat was scuttled. She is still lying there on the sea bed. Emmrich then gave the false statement to the British about how she was sunk in the Catalina attack.

Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus and sailed equipped with it in May 1945 but it was of course installed prior to that date. Read more about the Schnorchel and see list of fitted boats.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-320 did not suffer any casualties (we know of) until the time of her loss.
