Five days later, on the night of 10 September, "U-501" was taking part in a mass attack on Allied Convoy SC 42 in the Denmark Strait south of Tasiilaq, Greenland, in position , when she was detected by the Canadian with sonar, and damaged with depth charges. "U-501"s captain - Hugo Förster - decided to scuttle the U-boat. On the surface, she was spotted by the corvette , which attempted to ram her. However, "U-501" turned at the last moment so that the two vessels were running parallel, only feet apart. For unknown reasons, Hugo Förster surrendered himself and abandoned his command by leaping from the submarine's bridge to the deck of the "Moose Jaw".
