What is the significance of battle of saratoga?

As a result of the colonists defeating the British at Saratoga, France agreed to aid the colonists and send their navy to fight the British navy (which they did at Yorktown, VA). Saratoga stopped the British army in Northern New York and changed the Revolutionary War from largely being fought in the Northeast to being fought in the central and southern part of the 13 colonies.
These crucial colonist victories at Battle of Saratoga persuaded French to support Americans with military aid, and is considered the major turning point in the American Revolution.
