The Battle of Quebec (December 31, 1775) between American Continental Army forces and marked a turning point in the history of New France and what would eventually become Canada. The British established a strong presence in New France. The British defended Quebec City early in the American Revolutionary War. The battle was the first major defeat of the war for the Americans, and it came with heavy losses. General Richard Montgomery was killed, Benedict Arnold was wounded, and Daniel Morgan and more than 400 men were taken prisoner. The city's garrison, a motley assortment of regular troops and militia led by Quebec's provincial governor, General Guy Carleton, suffered a small number of casualties.
The Battles of Saratoga (September 19 and October 7, 1777) marked the climax of the Saratoga campaign, giving a decisive victory to the Americans over the British in the American Revolutionary War. British General John Burgoyne led a large invasion army southward from Canada in the Champlain Valley, hoping to meet a similar British force marching northward from New York City and another British force marching eastward from Lake Ontario; the southern and western forces never arrived, and Burgoyne was surrounded by American forces in upstate New York. He fought two small battles to break out which took place 18 days apart on the same ground, 9 miles (14 km) south of Saratoga, New York. They both failed.
The Siege (battle) of Yorktown (September 28 - October 19, 1781). The last battle of the Revolutionary War was the Battle of Yorktown, Virginia. The siege of Yorktown, was a decisive victory by a combined force of the American Continental Army troops led by General George Washington and Gilbert du Motier, Marquis de Lafayette, and French Army troops led by Comte de Rochambeau over a British army commanded by British peer and Lieutenant General Charles Cornwallis
