As part of the British expedition to the Chesapeake Bay in the middle of 1814, a naval force under Commodore James Alexander Gordon was ordered to sail up the Potomac River and attack Fort Washington.
[3] Its garrison consisted of 49 men under Captain Samuel T. Dyson of the United States Army's Corps of Artillery and elements of the U.S. 9th and 12th Infantry Regiments.
[9] Gordon's report on the bombardment stated that: A little before sunset the squadron anchored just out of gunshot; the bomb vessels at once took up their position to cover the frigates in the projected attack at daylight next morning and began throwing shells until about 7:00 pm.
The town's Common Council had earlier sent a delegation to offer the city's surrender to Rear Admiral George Cockburn, who was occupying Washington.
In the subsequent Congressional Investigative Committee report on the burning of the capital and the surrender of Alexandria, the town's clerk, Israel Thompson, submitted the following account:
The British thus acquired twenty-two merchant ships and vast quantities of loot, including flour, cotton, tobacco, wines and cigars.
[10] Commodore John Rodgers, with the crews of two frigates under construction (USS Guerriere and Java), twice tried to send fireships against Gordon's ships, but both attempts were foiled by British seamen in the squadron's launches and cutters.
Although the raid had been very successful in financial terms, the delays caused by the difficult navigation of the Potomac prevented Gordon from supporting the attack on Washington.
