Chesapeake Bay Journal: Mount Calvert allows visitors to re-imagine War of 1812 - April 2011

When the first gunboats exploded on the Patuxent River, everyone at Mount Calvert heard the blast. It was an ominous sound.

The year was 1814, and the United States was once again at war with Britain. Thousands of British troops were marching through southern Maryland to attack Washington.

At the same time, British ships sailed up the Patuxent River, moving more troops inland while chasing a troublesome collection of U.S. gunboats. Led by the bold U.S. Commodore Joshua Barney, these gunboats had been the only naval force to challenge British invaders on the Chesapeake Bay.
