"COAST GUARD CUTTER SINKS SUB -- Coast Guardsmen on the deck of U.S. Coast Guard cutter SPENCER watch the explosion of a depth charge which blasted a Nazi U-Boat's [U-175] hope of breaking into the center of a large convoy. The depth charge tossed from the 327-foot cutter blew the submarine to the surface, where it was engaged by Coast Guardsmen. Ships of the convoy may be seen in the background."
