The USS Abel P. Upshur (DD-193) was a Clemson-class destroyer built for the United States Navy, laid down on August 20, 1918, by Newport News Shipbuilding & Dry-dock Co. She was launched on February 14, 1920, and commissioned at Norfolk Navy Yard on November 23, 1920. As a Clemson-class vessel, she featured the typical characteristics of early 20th-century destroyers, designed for fleet screening and patrol duties. Initially assigned to Destroyer Division 37, Squadron 3 of the Atlantic Fleet, USS Abel P. Upshur primarily operated along the U.S. East Coast, participating in fleet exercises and maneuvers. Her active service was relatively brief, as she was decommissioned on August 7, 1922, at Philadelphia. She later served as a training ship for Naval Reserve personnel at the Washington Navy Yard from 1928 until 1930, after which her name was struck from the Navy list and transferred to the U.S. Treasury Department. During this period, she served the Coast Guard in efforts to prevent liquor smuggling into the U.S. Reclaimed by the Navy in 1934, she was recommissioned and operated along the Atlantic coast on the Neutrality Patrol. On September 9, 1940, she was decommissioned at Halifax, Nova Scotia, and transferred to Britain as part of the destroyers-for-bases agreement. Renamed HMS Clare, she joined the Royal Navy’s 1st Town Flotilla and arrived at Belfast on September 26, 1940. As HMS Clare, she was extensively modified for convoy escort duties, including the removal of two forward boilers to increase fuel capacity, which reduced her speed to 25 knots, and the removal of some armament to accommodate more depth charges and anti-submarine weapons like Hedgehog mortars. She participated in crucial wartime operations, including the landings in North Africa (Operation Torch) in November 1942, where she claimed to have sunk a German U-boat. She also took part in the invasion of Sicily in 1943 and served in the Western Approaches, performing convoy escort missions and anti-submarine patrols. HMS Clare was eventually reduced to reserve in August 1945, declared obsolete, and scrapped in 1947 at Troon. Her service exemplifies the versatility and strategic importance of Clemson-class destroyers during both peacetime and World War II, especially in convoy escort and amphibious operations.
