| History | Built as American motor yacht Alva for W.K. Vanderbilt, New York. On 4 Nov, 1941, given to the US Navy and placed in reduced commission under Cmdr F.W. Schmidt at Jacksonville on 29 December. On 22 Jan, 1942, the ship entered the Norfolk Navy yard to be converted to the patrol gunboat USS Plymouth (PG 57), armed with one 4in and four 3in guns. On 20 April, she was fully commissioned, based in Norfolk and assigned to the Inshore Patrol Squadron in the 5th Naval District. She made several convoy escort voyages between New York, Key West and Guantanamo during 1942/43. | ||
| Notes on loss | At 21.37 hours on 5 Aug, 1943, the USS Plymouth (PG 57) (Lt Ormsby M. Mitchel, Jr., USNR) was hit by one torpedo from U-566 about 120 miles southeast of Cape Henry, Virginia. The gunboat had made a underwater sound contact while escorting a coastal convoy, just as the ship swung left to bear on the target she was struck just abaft the bridge. The ship rolled first to starboard, then took a heavy list to port with the entire port side forward of amidships in flames and sank within two minutes. The survivors were picked up by the US Coast Guard cutter USS Calypso in heavy seas and arrived in Norfolk on 6 August. The commander Lt Ormsby M. Mitchel, Jr. was awarded the Navy Cross for extraordinary heroism. He had been thrown violently against a bulkhead and sustained serious injuries, which later required amputation of his left leg. Despite his own condition, he directed abandon ship operations and remained at his post until the ship went down. | ||
