"It seems hard to understand how Jameson could be so foolish as to decide as he did, to send the prisoner immediately to Arnold. He knew that some of the papers were in Arnold's undisguised handwriting, and it seems unaccountable that the circumstances under which they had come into his hands should not have opened his eyes to the treachery of that officer. He wrote a letter to Arnold saying that he sent a certain Mr. Anderson forward under the charge of Lieutenant Allen and a guard, Anderson having been taken while on his way to New York; adding, 'He had a passport signed in your name, and a parcel of papers taken from under his stockings which I think of a very dangerous tendency.' He went on to describe the papers and to say that he had sent them to Washington. "Major Tallmadge, who was next in command to Jameson, was that day on duty farther down the river. When he returned in the evening and heard of the circumstances, he was filled with astonishment at Jameson's folly, and boldly expressed his doubts of Arnold's fidelity. He offered to take upon himself the entire responsibility of acting on the belief of his guilt, if Jameson would consent. But Jameson refused to allow anything that would seem to imply distrust of Arnold. "Then Tallmadge earnestly begged of him to have the prisoner brought back. Jameson gave an unwilling consent to that, but insisted on forwarding his letter and informing the general why the prisoner was not sent on. That was the letter Arnold received in time to enable him to make his escape to the _Vulture_. "Jameson at once sent an express after Lieutenant Allen, who had Andre in charge, directing him to take his prisoner back to headquarters at North Castle. "When Major Tallmadge saw Andre, and noticed his manner and gait as he paced the room, he felt convinced that he was a military man and more than ever certain that Arnold was indeed a traitor. He talked the matter over with Jameson and partly convinced him. The result was the removal of Andre to Colonel Sheldon's quarters at North Salem, as a more secure place. "There Andre wrote a letter to Washington, giving his name and rank and a brief account of the occurrences which had brought him into his present situation. This he handed to Major Tallmadge, who learned with astonishment that his prisoner was the adjutant-general of the British Army.
