France Allies with the Patriots

During the American Revolution patriots or the Continental Army was a very weak group of people. They were not professional fighters, had no training nor weapons for them to fight, but they had two very important aspects, they were all fighting for one reason, independence while british soldiers where fighting for money. Another very important aspect  was the help they got from the French. 
French entered the war after "The Battle of Saratoga" in 1778. French wanted to defeat the British Army which was the most powerful of that time. They helped Patriots in many aspects during their fight for independence, french Generals trained the farmers of the continental army they sent weapons and soldiers to help fight the battle. 
One of the most important things French did for Patriots was that, George Washington wanted to trap General Cornwallis in Virginia when he was marching back to the north from the battles of the south that left the general frustrated. So a French troop trapped the in Yorktown in June waiting for a French fleet to block the ports and Washington's Army to march down. Washington and the French fleet had the right army, the port was blocked and Cornwallis decided to surrender.
