The Battle of Saratoga was an incredible turn of fortunes for the United States. British Gen. John Burgoyne thought he would cut off New England from the rest of the colonies. Instead, he lost the battle and was forced to surrender 20,000 troops. Saratoga was also Benedict Arnold's finest hour. He loathed American commander Horatio Gates, who relieved Arnold of his command. Nonetheless, at the Battle of Bemis Heights on October 7, 1777, Arnold took command of American soldiers whom he led in an assault against the British. Arnold’s fierce attack disordered the enemy and led to an American victory. The decisive Patriot victory compelled France to enter the war as an ally with the United States.
