The USS Relief, launched on 14 September 1836 at the Philadelphia Navy Yard, was a notable United States Navy supply ship designed by Samuel Humphreys. Constructed along merchant vessel lines, Relief featured three masts equipped with a trysail mast and gaffsails, enabling her to work effectively to windward in strong winds. Her hull was pierced for 16 small guns, although her typical armament consisted of only four to six 18-pounder guns and two 12-pounders, emphasizing her primary role as a supply vessel rather than a combatant. Relief’s service began shortly after her launch when she was commanded by Lieutenant Thomas A. Dornin and departed Philadelphia in December 1836 to join the South Sea Surveying and Exploring Expedition. Due to delays in the expedition caused by logistical and administrative issues, she remained in the eastern United States for 19 months before setting sail in August 1838 under Lt. Charles Wilkes. During this voyage, Relief proved to be a slow sailer, often falling behind her squadron. Despite this, she participated in significant exploratory missions, including navigating the Strait of Magellan, where she was nearly wrecked off Noir Island in March 1839 due to storms and the loss of her anchor. Throughout her operational career, Relief engaged in various surveying, resupply, and patrol missions across the Pacific, South America, and the Atlantic. She served in the Mexican-American War, supporting the blockade of Mexican coasts from 1847 to 1848, and later operated in the Mediterranean, Atlantic, and Asiatic stations. Her duties included resupply runs, maintaining supply lines during wartime, and serving as a station store ship. Decommissioned and recommissioned multiple times, Relief was eventually sold in 1883. Relief’s extensive service history highlights her importance as a versatile supply vessel, supporting exploration, military campaigns, and naval operations across multiple oceanic regions during the mid-19th century. Her design, operational endurance, and participation in key exploratory and wartime missions mark her as a significant vessel in maritime history.
