1. Explosive Scene Marker
Inscription. Imagine this scene on August 22, 1814, when explosions erupted on the Patuxent! The U.S. Chesapeake Flotilla scuttled their own vessels when British pursuers approached. With the flotilla destroyed, the British landed about 500 troops at Mount Calvert. From here they marched to Upper Marlboro to join the main British invasion force.

“I instantly sent orders for our Marines and Naval Forces at Pig Point to be forthwith moved to Mount Calvert and…with the utmost expedition to join the Army, which I also most readily agreed to accompany.”
– British Rear Adm. George Cockburn to Vice Adm. Alexander F.I. Cochrane, August 27, 1814

On to Washington
Anchored off Mount Calvert, British Rear Admiral Cockburn reported “the complete destruction of this Flotilla of the Enemy which has lately occupied So much of our attention.” Cockburn set out to join the assault on Washington, D.C. At the same time, Joshua Barney with 400 American flotillamen rushed to help defend the capital.
