American surface combatants and two blimps sank a German U-boat off Point Judith, Rhode Island in one of the last actions of the Battle of the Atlantic.

On May 6 she was en route to Boston, Massachusetts with United States Navy Armed Guard onboard to protect the ship.

The President of the German Reich Karl Dönitz directed all U-boats to cease attacks on 4 May, ahead of Germany's surrender.

[5] A radio report about the torpedoing from one of the rescue ships, the SS Kamen, was picked up by US Navy's Eastern Sea Frontier command in New York and by the 1st Naval District in Boston.

Ericsson was transiting the Cape Cod Canal with McCune on board when the summons came, so the remaining four ships headed for Kamen's location, with Tollaksen in temporary command.

When the first ships arrived at Point Judith at 19.30, they began sweeping the area with their late-war Sonar equipment.

After the warships had made their first attack, oil was sighted on the surface sparking the first series of claims that the U-boat had been destroyed.

At 0530, oil, planking, life rafts, a chart tabletop, clothing, and an officer's cap were spotted on the surface.

During the 17-hour hunt, the warships from TF60.7 had expended 264 Hedgehog bombs and 95 depth charges; at least one ship was damaged by the concussion from the ordnance exploding in shallow waters.
