 The British burned the barracks as they left.In 1807-1812, the abandoned fort was reconstructed with six guns as Fort Nathan Hale under the second system of US fortifications, and it served to defend the port from the British once again during the War of 1812.In 1863, Fort Nathan Hale II was built alongside the original fort, out of concern that Southern raiders might strike the city during the Civil War, but the fort saw no battle action.
