Importance during Revolutionary Era
In the beginning of the war, Arnold assisted in the capturing of the British garrison of Fort Ticonderoga in 1775. He also helped during a British invasion of New York at the Battle of Lake Champlain. In 1777, he was an important part in bringing about the surrender of British General John Burgoyne's army at Saratoga. He did not think he got the recognition he believed in deserve, so in 1779 he began secretly negotiating with the British, and agreed to turn over the U.S. post at West Point in exchange for money and a command in the British army. Even though his secret actions were discovered, he had escaped to British lines. His name has been synonymous with "traitor."
