On September 11, 1777, the American General George Washington in an attempt to protect Philadelphia, engaged the British General Sir William Howe in the Battle of Brandywine, the largest battle of the American Revolution. That 11-hour Battle encompassed more troops (nearly 30,000) over more land (10 square miles) than any combat fought on American soil until the American Civil War.
