As shown on the History Channel. July 9, 1776. The Declaration of Independence is read to crowds in New York. Offshore, more than 400 ships bristling with soldiers and guns are massing. It is the largest British invasion force until D-Day. America's 13 colonies have taken on the might of the world's leading superpower. Within months, George Washington's army has been decimated and defeat seems inevitable. Yet by 1783, America is free. American forces learn the hard way how to master the landscape, new weapons, and unconventional battle tactics. And with this elite force, forged through revolution, Washington saps the strength of the British Army to prevail in what has become a titanic battle of wills. As the British leave, a new nation, the United States of America, is born.
