The American Revolution seems doomed as the British army launches a bold new campaign in the South, but unsung patriots help reverse the course of the war and shock the world: Elizabeth Burgin helps POWs escape from British prison ships in New York in 1778; Peter Francisco is known for his size and strength on battlefields in Pennsylvania, New Jersey, and South Carolina; and James Armistead, a slave, serves as a spy who gathers intelligence before the Battle of Yorktown in the fall of 1781.
