Which battle convinced France that the American revolutionary cause had a strong chance of success?

The Battle of Saratoga convinced France that the American revolutionary cause had a strong chance of success.

The Battles of Saratoga were fought in New York in September and October 1777. American forces ultimately compelled British General John Burgoyne to surrender his army at Saratoga on October 17. The victory demonstrated that the Continental forces could defeat a major British campaign, rather than merely conduct local resistance.

News of Saratoga helped persuade France to enter a formal alliance with the United States. France signed the Treaty of Alliance and the Treaty of Amity and Commerce on February 6, 1778. French military and financial support greatly expanded the conflict and contributed to the eventual American victory.

Saratoga was a campaign consisting of multiple engagements, including Freeman’s Farm and Bemis Heights, rather than one single clash on one date. Yorktown was the later decisive siege that led to Cornwallis’s surrender. The connection between Saratoga and French intervention is one of the clearest examples of a battlefield result reshaping the international history remembered through America250.
