The crossing site is marked by the creation of two historic parks: Washington Crossing State Park, New Jersey, created in 1912, and Washington Crossing Historic Park, Pennsylvania, created in 1917. Washington Crossing illustrates how these two parks commemorate George Washington's courage to lead his army across the ice-choked Delaware River on Christmas night 1776 to attack an isolated garrison of Hessians located at Trenton, which would turn the tide of the American Revolution. Filled with images from the collections of historian Peter Osborne, the Washington Crossing Foundation, the Bucks County Historical Society, the Trenton Free Public Library, and the Metropolitan Museum of Art, the book includes an exposé of Emanuel Leutze's famous painting —a world-renowned symbol of freedom.
