Attacks on this boat

3 May 1944
A strange incident in which a Liberator aircraft illuminated HMS Hargood (K 582) at night while hunting for a German U-boat east of Conception Bay, Newfoundland. U-548, sensing they were the intended target fired at the aircraft which wrongly assumed the destroyer escort had done so and aborted the attack. The U-boat went unnoticed by the Allies. (Sources: Blair, vol 2, page 562)

6 May 1944
After having sunk the Canadian frigate Valleyfield other Allied escorts (after finally figuring out what happened) turn to hunt for the boat but again she escapes. (Sources: Blair, vol 2, page 562)

2 recorded attacks on this boat.

Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus and sailed equipped with it in August 1944 but it was of course installed prior to that date. Read more about the Schnorchel and see list of fitted boats.
