Although heavily-fortified locations were not attacked in the War of 1812, the British managed to bypass or suppress the weak defenses at the mouth of Chesapeake Bay and burn Washington, DC. As a result, Congress approved a large-scale program of improved masonry forts, later called the third system of US fortifications, to replace the relatively small forts of the first and second systems. Connecticut received a complete rebuild of Fort Trumbull and a rebuilt water battery at Fort Griswold under this program.
