A wooden bridge just upriver became the focal point on August 24, 1814, when American and British forces clashed in the Battle of Bladensburg. The British approached from the east, clarifying their intent to invade Washington. The Americans formed three defensive lines: the first here to protect the bridge, the second along present-day 40th Avenue, and the third at Fort Lincoln Cemetery at the District Line. At 1:00 p.m. the British stormed the bridge. More than 10,000 men battled here in heavy uniforms under sweltering conditions. The British veteran force of 4,500, commanded by Major General Robert Ross, had marched for four days carrying loaded packs in near 100-degree heat. Brigadier General William H. Winder commanded about 6,000 Americans, including 1,000 regulars, 400 Chesapeake Flotilla crewmen, 114 marines, and inexperienced militia.
