Brandywine Battlefield State Park is near the site of the Battle of Brandywine, where British general William Howe and his troops defeated George Washington on September 11, 1777, near Philadelphia, Pennsylvania. The Continental Army then fled to Chester, leaving Philadelphia vulnerable to British troops. The visitor center has displays about the battle that are a good introduction to the area's history. On the site are two restored Quaker farmhouses that once sheltered Washington and General Lafayette.
