The USS Mount Washington was a side-wheel steamer built in 1846 in Philadelphia, Pennsylvania. Originally named Mount Vernon, she was seized by the U.S. War Department on April 21, 1861, and transferred to the Union Navy for active service during the American Civil War. Following her acquisition, she was fitted out at the Washington Navy Yard, where she was briefly damaged as she struck the wharf during her preparations. Designed as a gunboat, she was assigned to patrol Confederate waterways, including the Potomac and Rappahannock Rivers. In her early service, she conducted reconnaissance missions, including an expedition up the Rappahannock River to Urbana, and captured or chased Confederate vessels. Notably, on June 26, 1861, she was dispatched to seize a small sloop convoying armed men from Maryland to Virginia, and she transported the captured USS Teaser from Nanjemoy to Washington, D.C. She also served as a utility vessel, carrying provisions and troops, such as transporting soldiers to Aiken’s Landing. In November 1861, she was renamed USS Mount Washington to avoid confusion with other vessels. During 1862, she continued logistical duties, arriving at Norfolk with supplies and towing other ships, including USS Passaic. Her most active year was 1863, during which she participated in the Siege of Suffolk, Virginia. She engaged Confederate forces at the mouth of the Nanpony River and exchanged artillery fire at Hampton Roads. Her crew distinguished themselves during the Battle of Suffolk in April, with four sailors earning the Medal of Honor. Throughout her service, Mount Washington sustained heavy damage, especially when riddled and disabled after engaging Confederate batteries at Hatt’s Point in May 1863. Despite these setbacks, she remained active, towing vessels and participating in naval operations along the James River and near Jamestown Island. She officially joined the North Atlantic Blockading Squadron at Norfolk in February 1865, serving as a supply ship until her decommissioning in April. The vessel was sold in Baltimore on June 21, 1865, and was subsequently redocumented in October 1865, continuing to serve in American commerce until 1880. Her service highlights her role as a versatile and resilient vessel during the Civil War, contributing both to naval combat and logistical support.
