As Sam Adams and John Hancock barely manage to escape, the superior British Royal Army massacres the rest of colonial militia at the famed Battle of Lexington. The two forces clash again at Concord, forcing the British to retreat back to Boston. While both sides prepare for an inevitable war, Sam and Hancock work with Ben Franklin to desperately convince the rest of the colonial representatives in Congress to support their cause--independence. When General Thomas Gage learns of his wife Margaret's affair with Sam's friend, Dr. Joseph Warren, Gage launches a full-out assault on the colonists at Bunker Hill. Sam uses the news of the battle to persuade the rest of the colonies to vote for independence. As British warships fire on Manhattan, The Revolutionary War begins, but the rebels will now face their enemy not as individual colonies, but as a single, united country.
