What's your opinion him? Do you believe he was pivotal in the colonies' defeat in the British? What I learned in my history classes is that he contributed greatly to the cause and was one of the main reasons that the colonies won the Battle of Saratoga. He was then unfairly rewarded or recognized and was ultimately left to defect. I can sympathize with him. Here you are, lead into battle against tyranny, and making pivotal decisions that brought the tides of war in your allies' favor, and others receive credit and you are unjustly recognized or rewarded? At the time, he may have realized living under British rule probably wasn't that bad in comparison to fighting and dying for a new government that wouldn't even recognize your sacrifices.
