U-398 was ordered to operate west of the English Channel and was not seen or heard of after sailing from Kristiansand in the evening of 17 April 1945. It was posted as missing after failing to return to port or signal its position after the cessation of hostilities.
This boat was fitted with a Schnorchel underwater-breathing apparatus in June 1944.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-398 did not suffer any casualties (we know of) until the time of her loss.
