District of Columbia, a single-screw tanker built in 1921 for the United States Shipping Board by the Baltimore Dry Dock and Shipbuilding Co., Baltimore, Md., was allocated to the Navy by the Maritime Commission in February 1945; renamed Serapis and designated IX213 on 9 March 1945, partially converted at San Francisco, and delivered to the Navy at Pearl Harbor and commissioned on 3 August 1945, Lt. (jg.) Eugene F. Dunne, USNR, in temporary command.
Acquired for temporary wartime use as a mobile floating storage unit for gasoline and diesel oil at Pearl Harbor and in the Trust Territories, Serapis was declared surplus after the cessation of hostilities in the Pacific. She remained at Pearl Harbor until 16 September when she was taken in tow by A TA-I 98 for her return to California. On 2 October, she arrived at San Francisco where she was decommissioned and returned to the Maritime Commission on 19 October. Her name was struck from the Navy list on 1 November 1945, and she was sold in May 1947 to the American Iron and Metal Co. for scrapping.
