He then continued on to Philadelphia where he met with members of Congress about his rank. His action at Ridgefield, coupled with the death of Wooster due to wounds sustained in the action, resulted in his promotion to major general, although his seniority was not restored over those who had been promoted before him. Amid negotiations over that issue, Arnold wrote out a letter of resignation on 11 July, the same day that word arrived in Philadelphia that Fort Ticonderoga had fallen to the British. Washington refused his resignation and ordered him north to assist with the defense there.
