The USS Duncan (DD-46) was a Cassin-class destroyer built for the United States Navy, launched on April 5, 1913, by the Fore River Shipbuilding Company in Quincy, Massachusetts. She was commissioned later that year on August 30, 1913. The vessel was named in honor of Commander Silas Duncan. Constructed as a typical early 20th-century destroyer, the USS Duncan served primarily along the East Coast and in Caribbean waters. Her initial activities included training, target practice, and exercises until she was placed out of commission at Boston on October 24, 1914. She was recommissioned on January 22, 1916, resuming operations that included the Neutrality Patrol and fleet exercises in the Caribbean. During this period, she also guarded the entrance to the York River. With the entry of the United States into World War I, Duncan’s service became more active and overseas-focused. On September 8–30, 1917, she escorted a convoy to an eastern rendezvous for escort out of England. Starting October 30, 1917, she sailed from New York to Brest, France, and subsequently operated from Queenstown, Ireland, where she engaged in convoy escort duties and anti-submarine patrols in the Irish Sea. Notable wartime actions include rescuing survivors of the Norwegian bark Miefield on July 17, 1918, and assisting after the collision of her sister ship Shaw with RMS Aquitania on October 9, 1918, where Duncan evacuated 84 crew members, including 12 wounded, and remained on scene while Shaw made her way to port. After the war, Duncan continued European operations, notably escorting President Woodrow Wilson’s ship, USS George Washington, into Brest on December 13, 1918. She returned to the United States arriving in Norfolk on January 12, 1919. Following her wartime service, Duncan was placed in ordinary at Norfolk on May 31, 1919, reduced to limited commission in 1920, and ultimately decommissioned on August 9, 1921. She was scrapped on March 8, 1935, in accordance with the London Naval Treaty. The USS Duncan’s service exemplifies the role of early 20th-century destroyers in both peacetime exercises and wartime convoy escort and rescue operations, highlighting her maritime significance during World War I.
