On 1 December 1861 in Mississippi Sound, Union screw steamer New London captured Advocate, a small fishing sloop flying Confederate colors. After the New York prize court condemned the vessel, the Navy purchased her, apparently to be sunk at Ship Island, Miss., to help form a temporary wharf at that Union Navy base. Records on the ship and her career are sparse—some indicating that, although she was paid for by the Federal Government, she was never actually delivered to the Navy—but it seems that Advocate was sunk as an obstruction in Petit Bois Channel, Ala. No details of this operation have been unearthed.

Advocate (AM-138) was laid down on 8 April 1942 at Tampa, Fla., by the Tampa Shipbuilding Co.; launched on 1 November 1942; sponsored by Mrs. A. K. Brown; and completed on 25 June 1943. She was transferred to the Soviet Navy that same day as T—111. The Soviets have retained her since that time. Advocate was carried on the American Navy list— as MSF-138 after 7 February 1955—until struck from that list on 1 January 1983.
