Then Arnold went on to Philadelphia, where he talked with members of Congress about his rank. Because of his good leadership at Ridgefield and because Wooster had died, Congress promoted Arnold to major general, although he did not outrank people who had been promoted before him. Arnold was not happy about this, and he tried to quit the army again. He wrote out a letter of resignation on July 11. But that day, people in Philadelphia learned that the British had captured Fort Ticonderoga. Again, Washington told Arnold he could not quit. Washington ordered Arnold to go north and help defend it.
