The USS Sentinel (AM-113) was an Auk-class minesweeper constructed for the United States Navy during World War II. Laid down on 28 November 1941 by the American Ship Building Company in Cleveland, Ohio, the vessel was launched on 23 May 1942 and commissioned on 3 November 1942. As a minesweeper, Sentinel was designed to detect and clear naval mines, playing a vital role in ensuring safe passage for Allied ships. Initially assigned to the Atlantic Fleet, Sentinel reported for duty in January 1943. Her early service included escorting operations and patrols along the U.S. East Coast and in the North Atlantic. Notably, on 20 February 1943, while escorting the vessel Merak from Bermuda to Norfolk, Sentinel engaged in her first enemy contact, detecting suspected submarine activity via echo-ranging equipment and attacking with depth charges, though without confirmed damage. Throughout her operational period, Sentinel participated in convoy escort missions and patrols across the North African coast, including Gibraltar, Oran, and Bizerte. In May 1943, she was involved in anti-submarine patrols and escort duty supporting the North African campaign, including the invasion of Sicily. During the invasion on 10 July 1943, Sentinel was part of Task Group 86.3 responsible for landing at Licata. A significant and harrowing event occurred during this operation when Sentinel was attacked by German aircraft. At approximately 0500, she was struck by bombs, one of which created a large hole in her after engine room. The attack caused severe damage: loss of power, destruction of communications, and injuries among her crew. Despite her heavy anti-aircraft fire and efforts to repel further attacks, Sentinel sustained critical damage. By 0615, with all power lost and listing heavily, she contacted nearby vessels for assistance. The crew evacuated the ship, which then capsized and sank at 1045 on 10 July 1943. Sentinel was struck from the Naval Vessel Register on 19 August 1943. Her service exemplifies the perilous nature of naval mine warfare and anti-aircraft combat during World War II, marking her as a notable vessel in wartime naval operations.
