On June 28, 1778, the American Army fought the British in the last northern battle of the Revolutionary War. The British withdrew from Philadelphia with a large train of supplies. General Washington carefully followed the British and, near Monmouth, New Jersey, ordered an attack on the rear of their train. The fight soon turned into a major engagement between the British and American forces. The American lines broke until General Washington arrived and single-handedly rallied the American troops. Although it was tactically a draw, this battle served as an important moral victory for the Americans, and they did indeed claim it as a victory. Although it can be claimed that they missed the chance for a great victory, it showed that the hard work that Washington, von Stueben and others had built at Valley Forge was used with success; and that for the first time, the discipline in the American Army created at Valley Forge helped to save them on the battlefield.
