The USS Viper was a heavily armed row galley built rapidly in 1814 at Vergennes, Vermont, to serve in the War of 1812. As the second vessel to bear the name, Viper was part of a fleet of six large row galleys constructed for operations on Lake Champlain. Her design focused on maneuverability and firepower, enabling her to play a significant role in the naval battles of the lake. Commissioned under Lieutenant Francis Mitchell, Viper participated prominently in the Battle of Plattsburgh on September 11, 1814. During this engagement, she supported the American squadron under Commodore Thomas Macdonough in defeating the British forces commanded by Commodore George Downie. Viper’s contributions helped drive the British gunboats back toward Canada, thwarting their invasion attempt and preventing the British from splitting the United States through the Lake Champlain corridor. This victory was pivotal in ending British plans to invade the northern states via the lake and significantly bolstered American negotiating leverage during the subsequent peace talks at Ghent. Viper’s construction was characterized by her robust build and strategic armament, though specific dimensions and armament details are not provided in the source. She remained active throughout the remainder of the war, serving as an integral part of the victorious squadron. Following the conclusion of hostilities, Viper was partially dismantled and laid up at Whitehall, New York. She was eventually sold at public auction there in 1825, ending her naval service. In summary, the USS Viper was a crucial naval asset during the War of 1812, notable for her role in the decisive Battle of Plattsburgh, her contribution to American naval dominance on Lake Champlain, and her embodiment of rapid wartime shipbuilding efforts. Her service underscores her maritime significance in early 19th-century American naval history.
