Why did Benedict Arnold become a traitor after helping the patriots?

Answer 1

Benedict Arnold became a traitor primarily due to his disillusionment with the American cause and dissatisfaction with his treatment by Congress. Despite his significant contributions to the Continental Army, including key victories, he felt undervalued and was frustrated by a lack of recognition and promotion. Additionally, Arnold was motivated by financial issues and a desire for personal gain, leading him to secretly negotiate with the British to surrender the fort at West Point. His betrayal ultimately stemmed from a combination of personal grievances and ideological shifts.
