Why was the battle of saratoga a turning point in the war

The battle of Saratoga was important for several reasons. First, it was a major victory for the Americans as they captured a large number of British soldiers. Second, it was a morale boost to the Americans who had been losing most of the Battles against the British. Third, it stopped the British army from meeting up with more British forces which were headed to Philadelphia in order to capture the city. Most importantly however, the battle gave the King of France confidence in the ability of the Continental Army, resulting in French military aid to the colonies.
