which battle during the revolutionary war changed the france mind about support the americas?

Answer 1

There really was not one battle that made the French enter the war on Americas side but rather it was the fact it was someone fighting against the British and holding their own and the fact that it was against the British that caused the French to fight against them. The French and British had fought against eachother so often and the French lost most of the time was another factor.

Answer 2

House in the Horse shoe.
