The History of the Several Towns, Manors, and Patents of the County of Westchester (1881 revised edition, Vol. I)
General Robertson said, that no military tribunal in Europe would decide the case of Andre to be that of a spy ; and he proposed to refer the question to Count de Rochambeau and General Knyphausen. Other considerations were urged by him, not so much in the way of argument as on the score of reciprocal benefits and humanity. He added that he should confide in General Greene's candor to represent in the fairest light to General Washington the arguments he had used; that he should stay on board all night, and hope in the morning to take back with him Major Andre, or an assurance of his safety."
" The British commissioners waited till morning, as General Robertson had proposed ; and at an early hour they received a note from General Greene, stating that he had communicated to Washington the subject of the conference, but that it had produced no change in his opinion and determination. Thrs intelligence was astounding to Robertson ; for he had written to Sir Henry Clinton the evening before, that he was persuaded Abdre would not be harmed. How he got this impression is not easily discovered ; since he represented General Greene as obstinately bent on considering Andre as a spy, and resisting all his arguments to the contrary.
Nothing more could be done by the commissioners. That no measure might be left untried however, General Robertson"6 addressed the following letter to General Washington, dated
Greyhound Schooner, Flag of Truck, Dobb's Ferry, Oct. 2, 1780. Sir : -- A note I had from 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 between 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.
