Sir : -- A note I liil fro:Ti General Greene leaves me in doubt if his memory had served him to relate to you, with exactness, the substance of the conversation that had passed betvvnen him and myself on the subject of Major Andre. In an affair of so much consequence to my friend, to the two armies, and humanity, I would leave no possibility of a misunderstanding, and therefore take the liberty to put in writing the substance of what I said to General Greene. I offered to prove by the evidence of Colonel Robinson and the officers of the Vulture, that Major Andre went on shore at General Arnold's desire, in a boat sent for him with a flag of truce ; that he not only came ashore with the knowledge and under the protection of the General who commanded in the district, but that he took no step while on shore, but by the direction of General Arnold, as will appear by the enclosed letter from him to your Excellency. Under these circumstances I could not, and hoped you would not, consider Major Andre as a spy, for any improper phrase in his letter to you.

The facts he relates correspond with evidence I offer, but he admits a conclusion which does not follow. The change of clothes 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 distinguished gentlemen of knowledge of the law of war and nations, might be asked their opinion on the subject, and mentioned Monsieur Knyphausen and General Rochambeau 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 the man should be exchanged, he had ordered him to be exchanged.
