Arnold and André finally met on 21 September at Joshua Hett Smith's house. On the morning of 22 September James Livingston, the colonel in charge of the outpost at Verplanck's Point, fired on HMS "Vulture", the ship that was intended to carry André back to New York. This action damaged the ship and she had to retreat downriver, forcing André to return to New York overland. Arnold wrote out passes for André so that he would be able to pass through the lines, and also gave him plans for West Point. On Saturday, 23 September André was captured, near Tarrytown, by three Westchester patriots named John Paulding, Isaac Van Wart and David Williams; the papers exposing the plot to capture West Point were found and sent to Washington, and Arnold's treachery came to light after Washington examined them. Meanwhile, André convinced the unsuspecting commanding officer to whom he was delivered, Colonel John Jameson, to send him back to Arnold at West Point. However, Major Benjamin Tallmadge, a member of Washington's secret service, insisted Jameson order the prisoner intercepted and brought back. Jameson reluctantly recalled the lieutenant delivering André into Arnold's custody, but then sent the same lieutenant as a messenger to notify Arnold of André's arrest.
