In August 1781, the Continental Army trapped Lieutenant General Charles Cornwallis in the Virginia coastal town of Yorktown. George Washington and the main army and Count de Rochambeau with his French army decided to march from the Hudson Highlands to Yorktown and deliver the final blow. But Washington's war chest was completely empty, as was that of Congress. Without food, uniforms and supplies, Washington's troops were close to mutiny. Washington determined that he needed at least $20,000 to finance the campaign. When Morris told him there were no funds and no credit available, Washington gave him a simple but eloquent order: "Send for Haym Salomon". Salomon raised $20,000, through the sale of bills of exchange. With that contribution, Washington conducted the Yorktown campaign, which proved to be the final battle of the Revolution.
