Famed for his bravery and grit, Arnold was regarded by Washington as his finest battlefield commander. He was the hero of Saratoga, a staunch defender of his commander-in-chief, and a mentor of sorts to Ben Tallmadge.
Over the course of Season 2, however, Arnold felt slighted by a country for which he had sacrificed so much of his fortune and health. Denied a return to the battlefield by Washington because of his wounds, Arnold was relegated to a desk job as military commandant of Philadelphia, where he renewed his acquaintance with the alluring Peggy Shippen. Unbeknownst to Arnold, Peggy's interest was designed to bring him into contact with John André, whom she hoped to wed. In Season 3, Arnold conspired with André to turn West Point over to the British but was found out and forced to flee, reviled by the patriots for his betrayal and by his fellow Redcoat officers for getting André caught and hanged.
Arnold goes on a rampage in Season 4, rounding up suspected spies along with innocent men and women. Eager to command a regiment of his own, he's finally given the funds to raise the Loyal American Legion to fight his nemesis General Washington. A brilliant military strategist, Arnold is keen to remind his former commander of his prowess on the battlefield.
