For America250, which battle helped persuade France to openly ally with the American revolutionaries?

The Battle of Saratoga helped persuade France to openly ally with the American revolutionaries.

The Saratoga campaign ended with the surrender of British General John Burgoyne’s army on October 17, 1777. The American victory demonstrated that the Continental forces could defeat a major British army, changing European assessments of the war.

France had already provided covert aid to the American cause, including weapons and supplies. After Saratoga, France signed the Treaty of Alliance and the Treaty of Amity and Commerce with the United States in February 1778. French military and naval support later played a decisive role, especially during the Yorktown campaign.

Saratoga is often described as a single battle, but the campaign included major engagements at Freeman’s Farm on September 19 and Bemis Heights on October 7. The American commander was Horatio Gates, while Benedict Arnold played a prominent battlefield role before later becoming famous for treason.
