Why was the Battle of Saratoga the most significant moment in bringing about victory in America's war for independence?

The battle of Saratoga was very important for a number of reasons. First, it convinced France that America was capable of and might just win the war against Great Britain. Because of that, France allied itself with America and committed its navy to America. Without that navy America could not have won at Yorktown. Second, it resulted in a large British army being destroyed so the British were no longer a threat in that area. And, it prevented the British from seizing control of the Hudson River. If the British had control of the Hudson, they would have split the colonies in two and perhaps conquered each part one at a time.

Hope that helps!(:
