War of 1812
Chesapeake campaign

The strategic location of the Chesapeake Bay near the Potomac River made it a prime target for the British. Rear Admiral George Cockburn arrived there in March 1813 and was joined by Admiral Warren who took command of operations ten days later. Starting in March a squadron under Cockburn started a blockade of the mouth of the Bay at Hampton Roads harbour and raided towns along the Bay from Norfolk, Virginia to Havre de Grace, Maryland. In late April Cockburn landed at and set fire to Frenchtown, Maryland and destroyed ships that were docked there. In the following weeks he routed the local militias and looted and burned three other towns. Thereafter he marched to iron foundry at Principio and destroyed it along with sixty-eight cannons.

On 4 July 1813, Commodore Joshua Barney, an American Revolutionary War naval officer, convinced the Navy Department to build the Chesapeake Bay Flotilla, a squadron of twenty barges powered by small sails or oars (sweeps) to defend the Chesapeake Bay. Launched in April 1814, the squadron was quickly cornered on the Patuxent River. While successful in harassing the Royal Navy, they could not stop subsequent British operations in the area.
