Treachery on September 21, 1780 (Guest post by GDD)
Benedict Arnold became a traitor to the Continental Army on September 21, 1780. After being given command of the American fort, West Point, he met with Major John Andre of the British Army to discuss the handing over of the fort and its men. In exchange, Arnold asked for wealth and a good position in the Red Coat army. Before the traitorous plot could ensue, George Washington arrived at the fort and became aware of the conspiracy. Arnold managed to escape and later moved to England, where he died in 1801.
