Benedict Arnold
Once he established himself at West Point, Arnold began systematically weakening its defenses and military strength. Needed repairs on the chain across the Hudson were never ordered.  Troops were liberally distributed within Arnold's command area (but only minimally at West Point itself), or furnished to Washington on request. He also peppered Washington with complaints about the lack of supplies, writing, "Everything is wanting". At the same time, he tried to drain West Point's supplies, so that a siege would be more likely to succeed. His subordinates, some of whom were long-time associates, grumbled about unnecessary distribution of supplies, and eventually concluded that Arnold was selling some of the supplies on the black market for personal gain.
