HMS Ambush, originally American Gunboat No. 5, was a small, single-masted vessel launched in Baltimore in 1805. Built by William Price to a design by Josiah Fox, she may have been a double-ender and was initially armed with two 32-pounder guns, one fore and one aft. Her construction featured 2,600 pounds of copper sheathing for hull protection and fittings, and she was rigged with a lateen sail, supported by a single mast amidships. Her early design included a dandy rig, false keels, and lee boards, allowing her to navigate the challenging waters of the Mediterranean. During her service, Gunboat No. 5 undertook various missions, including enforcing U.S. embargo laws and participating in naval operations during the early 19th century. She left Hampton Roads in May 1805, sailing to the Mediterranean, arriving in Gibraltar in June, and visiting ports such as Syracuse and Tunis. Although she did not see direct combat during her time there, she remained part of a squadron stationed in the Mediterranean until 1806 before returning to the United States. Back in American waters, she was stationed at Norfolk and later at Baltimore, where she helped enforce the Embargo Act of 1807. Her service was punctuated by an incident in June 1808 when a squall sank her off Holland Island, resulting in the loss of three crew members; she was subsequently raised and repaired. Over the following years, Gunboat No. 5’s armament varied, including a 24-pounder and several 6-pounder guns, reflecting her evolving role. In the buildup to the War of 1812, she participated in operations in Mobile, Alabama, capturing Fort Charlotte from the Spanish in April 1813. By 1814, under the command of Sailing Master Jonathan D. Ferris, she engaged in anti-piracy actions at Barataria Bay and took part in the Battle of Lake Borgne. During this battle, she was armed with a 24-pounder gun and four 12-pounder carronades, and her crew numbered 36. She was captured by British forces, who took her to the West Indies. The British formally purchased her in 1815, renamed her HMS Ambush, and used her in West Indies service before selling her later that year. Her capture and subsequent service highlight her maritime significance as a small but active vessel involved in key conflicts of her era.
