The USS Ethan Allen was a 556-ton bark constructed in 1859 in Boston, Massachusetts. Acquired by the Union Navy during the early stages of the American Civil War, she was officially purchased on August 23, 1861, and commissioned on October 3, 1861, under the command of Acting Volunteer Lieutenant W. B. Eaton. As a sailing vessel, the Ethan Allen was utilized primarily as a gunboat supporting the Union's blockade strategy against Confederate waterways. During her first wartime cruise from October 27, 1861, to March 30, 1863, the USS Ethan Allen operated in the Gulf of Mexico. Her patrols proved effective; she captured eight prizes—enemy vessels—and destroyed substantial salt works along Florida's coast. These actions significantly hindered the Confederate war effort and impacted civilian commerce by disrupting salt production, which was vital for food preservation and other uses. Following this deployment, the vessel returned to Boston for repairs. Between June 22 and October 28, 1863, she cruised along the New England coast, providing protection for merchant ships and fishing vessels against Southern Confederate cruisers. Later, on November 9, 1863, she departed from Boston to join the South Atlantic Blockading Squadron stationed off Port Royal, South Carolina, arriving on November 26. For the subsequent year and a half, Ethan Allen patrolled the Carolina coast, maintaining Union blockades and control of key waterways. She also served as a practice ship for junior officers within her squadron, contributing to the training of naval personnel. The USS Ethan Allen was decommissioned at Portsmouth, New Hampshire, on June 26, 1865, shortly after the end of the Civil War, and was sold on July 20, 1865. Her service exemplifies the maritime role of sailing vessels in Union blockade operations, and her diverse missions underscored the importance of naval enforcement of blockade strategies during the conflict.
