The facts he relates correspond with the evidence I offer; but he admits a conclusion that does not follow. The change of cloaths and name was ordered by General Arnold, under whose direction he necessarily was, while within his command. As General Greene and I did not agree in opinion, I wished, that disinterested gentlemen of knowledge of the law of war and nations, might be asked their opinion on the subject; and mentioned Monsieur Knyphaufen, and General Rochambault.
I related that a Captain Robinson had been delivered to Sir Henry Clinton as a spy, and undoubtedly was such; but that it being signified to him that you were desirous that this man should be exchanged, he had ordered him to be exchanged.
I wished that an intercourse of such civilities, as the rules of war admit of, might take off many of its horrors. I admitted that Major Andre had a great share of Sir Henry Clinton's esteem, and that he would be infinitely obliged by his liberation; and that if he was permitted to return with me, I would engage to have any person you would be pleased to name set at liberty.
I added, that Sir Henry Clinton had never put to death any person for a breach of the rules of war, though he had, and now has, many in his power. Under the present circumstances, much good may arise from humanity, much ill from the want of it. If that could give any weight, I beg leave to add, that your favourable treatment of Major Andre, will be a favour I should ever be intent to return to any you hold dear.
My memory does not retain with the exactness I could wish, the words of the letter which General Greene shewed me from Major Andre to your Excellency. For Sir Henry Clinton's satisfaction, I beg you will order a copy of it to be sent to me at New York.
I have the honour to be, your Excellency's Most obedient and most humble servant, JAMES ROBERTSON.
His Excellency General Washington.
New York, October 1, 1780.
SIR,
