  The siege of Yorktown was a decisive victory by the combined forces of the Continental Army commanded by Washington, the French Army commanded by General Comte de Rochambeau, and the French Navy commanded by Admiral de Grasse. On August 19, the march to Yorktown led by Washington and Rochambeau began, which is known now as the " celebrated march ". Washington was in command of an army of 7,800 Frenchmen, 3,100 militia, and 8,000 Continentals. Inexperienced in siege warfare, he often deferred to the judgment of General Rochambeau and relied on his advice. Despite this, Rochambeau never challenged Washington's authority as the battle's commanding officer.
  
  By late September, Patriot-French forces surrounded Yorktown, trapped the British Army, and prevented British reinforcements from Clinton in the North, while the French navy emerged victorious at the Battle of the Chesapeake. The final American offensive began with a shot fired by Washington. The siege ended with a British surrender on October 19, 1781; over 7,000 British soldiers became prisoners of war. Washington negotiated the terms of surrender for two days, and the official signing ceremony took place on October 19; Cornwallis claimed illness and was absent, sending General Charles O'Hara as his proxy. As a gesture of goodwill, Washington held a dinner for the American, French, and British generals, all of whom fraternized on friendly terms and identified with one another as members of the same professional military caste.
  
  Afterwards, Washington moved the army to New Windsor, New York where they remained stationed until the Treaty of Paris was signed on September 3, 1783, formally ending the war. Although the peace treaty did not happen for two years following the end of the battle, Yorktown proved to be the last significant battle or campaign of the Revolutionary War, with the British Parliament agreeing to cease hostilities in March 1782.
