The Revolutionary War begins when British General Gage orders a 700-man force to destroy American Patriot munition supplies in Concord, Massachusetts. The British march to Lexington and are confronted by a small Patriot militia force. A shot is fired (no one knows who fired first) and the British open fire killing several Patriots. The British column continues to Concord where they are attacked by a larger group of Patriots. Under constant ambush, the British force barely makes it back to Boston.
