September 11, 1777: Washington's Defeat at Brandywine Dooms Philadelphia

The Battle of Brandywine was the largest land battle of the American Revolution and the major conflict of the Philadelphia campaign that ended with Washington's army spending a hard winter at Valley Forge. Brandywine was also the first battle for a young French volunteer, the Marquis de Lafayette. Lafayette suffered a leg wound during the conflict. British Captain Patrick Ferguson's new invention, a breech-loading rifle, was also used for the first time at Brandywine. Ferguson had a chance to alter history that day as he had Washington in the sights of his weapon but declined to fire upon the brave Washington.
