USS Herndon (DD-198) was a Clemson-class destroyer constructed for the United States Navy, launched on 31 May 1919 by Newport News Shipbuilding & Dry Dock Company. She was the first Navy vessel named after Commander William Lewis Herndon. Commissioned on 14 September 1920 at Norfolk, Virginia, Herndon initially underwent shakedown in New England waters before being placed in reserve at Charleston, South Carolina, on 3 November 1920. She served primarily in a reserve capacity along the U.S. East Coast until her decommissioning at Philadelphia on 6 June 1922. From 1930 to 1934, Herndon served in the U.S. Coast Guard as CG-17 during the Rum Patrol, enforcing Prohibition-era regulations. She was recommissioned into the U.S. Navy on 4 December 1939, rejoining active service as tensions escalated prior to World War II. In early 1940, she joined the Caribbean Neutrality Patrol, operating out of Guantanamo Bay and the Panama Canal Zone, conducting tactical and antisubmarine maneuvers. Herndon’s maritime significance extends beyond her U.S. service, as she was transferred to the Royal Navy under the Destroyers for Bases Agreement on 9 September 1940. Renamed HMS Churchill, she became a leader of the first Town-class flotilla, escorting transatlantic convoys and patrolling off the Western Approaches during WWII. Notably, HMS Churchill participated in the search for the German battleship Bismarck and was visited by Winston Churchill in August 1941. Modifications included removing some armament for increased anti-submarine capacity, such as depth charges and Hedgehog mortars. She escorted convoys like HX 186 and ON 94 and supported Operation Torch preparations. In July 1944, she was transferred to the Soviet Navy, renamed Deyatelny, and served in the Arctic convoy routes. Her service ended when she was sunk in the Kara Sea east of Cape Terebirski, either by U-956 or due to an accidental explosion of her depth charges, resulting in the loss of 117 of her 124 crew members. Her legacy is preserved through artifacts such as her ship’s bell, which remains a tangible link to her storied history.
