Robinson’s house in the Highlands Septr 26th 1780
I have the honor to inform Congress that I arrived here yesterday about 12 o’clock on my return from Hartford. Some hours previous to my arrival Major Genl Arnold went from his quarters which were at this place, and as it was supposed over the river to the garrison at West-point, whither I proceeded myself in order to visit the post. I found General Arnold had not been there during the day, and on my return to his quarters, he was still absent. In the mean time a packet had arrived from Lt Colonel Jamison, announcing the capture of a John Anderson who was endeavouring to go to New-York, with the several interesting and important papers mentioned below, all in the hand writing of General Arnold. This was all accompanied with a letter from the prisoner avowing himself to be Major John André Adjt General of the British army, relating the manner of his capture, and endeavouring to shew that he did not come under the description of a spy. From these several circumstances, and information that the General seemed to be thrown into some degree of agitation on receiving a letter a little time before he went from his quarters, I was led to conclude immediately that he had heard of Major Andre’s captivity, and that he would if possible escape to the enemy, and accordingly took such measures as appeared the most probable to apprehend him. But he had embarked in a barge, and proceeded down the river under a flag to the vulture ship of war, which lay at some miles below Stoney and Verplank’s points. He wrote me after he got on board a letter, of which the inclosed is a copy. Major André is not arrived yet, but I hope he is secure & that he will be here to-day. I have been, and am taking precautions, which I trust will prove effective, to prevent the important consequences which this conduct on the part of General Arnold was intended to produce. I do not know the party that took Major André, but it is said, that it consisted only of a few militia, who acted in such a manner upon the occasion as does them the highest honor and proves them to be men of great virtue. They were offered, I am informed, a large sum of money for his release, and as many goods as they would demand, but without any effect. Their conduct gives them a just claim to the thanks of their country, and I also hope they will be otherwise rewarded. As soon as I know their names I shall take pleasure in transmitting them to Congress.
I have taken such measures with respect to the Gentlemen of General Arnolds family as prudence dictated; but from every thing that has hitherto come to my knowledge, I have the greatest reason to believe that they are perfectly innocent—I early secured—Joshua Smith, the person mentioned in the close of General Arnolds letter, and find him to have had a considerable share in this business.
I have the honor to be, with regard, Sir Your Excellency’s most obt & hble sert
