Did Alexander Hamilton stay behind at Robinson’s house, receive the packet taken off John André (which revealed Benedict Arnold’s treason), and give it to Washington?

Michael E. Newton's Alexander Hamilton: The Formative Years 400pxAn extract from Alexander Hamilton: The Formative Years (a continuation from the previous post):

According to nearly all historians, Alexander Hamilton remained at the Robinson house while Washington went over to West Point and it was Hamilton who received the important packet of papers during the commander-in-chief’s absence.* Indeed, a number of contemporary reports and subsequent eyewitness accounts state explicitly that Hamilton stayed behind at Arnold’s headquarters and received the packet. However, these reports disagree on many details and have numerous other problems that call their accuracy into question.

After one-and-a-half pages of analyzing the various reports that had Hamilton receiving the packet and showing how and why they are not reliable, Alexander Hamilton: The Formative Years continues:

Most contemporary reports regarding the events of September 25 make no mention of Hamilton staying at the Robinson house and receiving the packet. The anonymous letter written by James McHenry dated September 26 and published in The Pennsylvania Packet a week later says nothing about Hamilton staying behind and receiving the packet, even though it mentions Hamilton’s later pursuit of Arnold. Another account dated September 28 and printed in the same issue of The Pennsylvania Packetalso makes no mention of Hamilton staying behind and receiving the packet, even though it too mentions Hamilton chasing after Arnold. Washington did not mention Hamilton in his report to Congress, nor in any of his other letters about the events of this day. Hamilton did not mention staying behind or receiving the packet in his letter to his fiancée, even though he mentioned his pursuit of Arnold. Lafayette also failed to mention Hamilton staying behind and receiving the packet in his letter written at the time, even though he also mentioned Hamilton’s pursuit of Arnold. Furthermore, no known published account or history prior to 1828 claimed that Hamilton stayed behind at the Robinson house and received the packet. Lack of evidence is not evidence, but it is telling that the story of Hamilton receiving the packet in Washington’s absence was not mentioned in any published work for nearly fifty years after the event.

There is, however, one first-hand account indicating that Hamilton travelled with Washington to West Point instead of staying behind at the Robinson house. In a letter to his fiancée, Alexander Hamilton wrote, “I went in pursuit of [Arnold] but was much too late, and I could hardly regret the disappointment when, on my return, I saw an amiable woman frantic with distress for the loss of a husband she tenderly loved.” Thus, Hamilton clearly stated that it was only after he returned from his pursuit of Arnold that he witnessed Peggy Arnold’s “distress.”

According to all accounts, Peggy Arnold started swooning and acting frantic just after Washington left Robinson’s house for West Point and long before he returned from there. David S. Franks added that “Mrs. Arnold’s unhappy situation called us all to her assistance.” Thus, if Hamilton had stayed at Robinson’s house, he not only would have heard Peggy’s distress, but he also would have been among those who assisted her. In fact, a number of historians have said that this is exactly what happened. Since Hamilton wrote that he did not witness Peggy’s distress until after he returned from chasing Benedict Arnold, he could not have been at the Robinson house during Washington’s visit to West Point and could not have received the packet of documents taken from John André. Instead, Hamilton must have gone over to West Point with George Washington, Henry Knox, Lafayette, and the rest of the party.

In stating that “nearly all historians” place Hamilton at Robinson’s house, this is not meant to imply that some historians have argued against the mainstream account. Rather, some historians simply report that the packet arrived for Washington without stating who received it.
