Recounts the events of the Boston battle that ignited the American Revolution, tracing the experiences of Patriot leader Dr. Joseph Warren, a newly recruited George Washington, and British General William Howe. Boston, Massachusetts in 1775 is an island city occupied by British troops after a series of incendiary incidents by patriots who range from citizens to vigilantes. After the Boston Tea Party, British and American soldiers and Massachusetts residents have maneuvered around each other until April 19th, when violence erupts at Lexington and Concord. In June, with the city cut off from supplies by a British blockade and Patriot militia poised in siege, skirmishes give way to war in the Battle of Bunker Hill.
