Arnold learned of André's capture the morning of 24 September while waiting for Washington, with whom he was going to have breakfast at his headquarters in British Col. Beverley Robinson's former summer house on the east bank of the Hudson. Upon receiving Jameson's message, however, he learned that Jameson had sent Washington the papers which André was carrying. Arnold immediately hastened to the shore and ordered bargemen to row him downriver to where HMS "Vulture" was anchored, fleeing on it to New York City. From the ship, he wrote a letter to Washington requesting that Peggy be given safe passage to her family in Philadelphia—which Washington granted.
