Cunningham mentioned to Newton that, on the preceding night, he had a very extraordinary dream, which he could not get out of his head. He had fancied himself in a forest; the place was strange to him; and, whilst looking about, he perceived a horseman approaching at great speed, who had scarcely reached the spot where the dreamer stood, when three men rushed out of the thicket, and, seizing the bridle, hurried him away, after closely searching his person. The countenance of the stranger being very interesting, the sympathy felt by the sleeper for his apparent misfortune awoke him; but he presently fell asleep again, and dreamt that he was standing near a great city, amongst thousands of people, and that he saw the same person he had seen seized in the wood, brought out and suspended to a gallows. When Andre and Miss Seward arrived, he was horror-struck to perceive that his new acquaintance was the antitype of man in the dream."

In the 3d November, 1775, he was taken prisoner with the garrison by the Americans under General Montgomery at St. John' s in Canada. Towards the close of the year 1776 most of the prisoners made by either side in Canada were exchanged and Andre thus obtained his freedom by their means, through whom he had lost it. The skeleton of the Seventh was transferred from that Province to New York; recruits and new clothing were sent out from England ; and in the end of December, the regiment, including the men lately discharged from Pennsylvania, marched into town with tolerably full ranks. Andre did not, however, long remain in it; on the 18th January, 1777, he received a captaincy in the Twenty-sixth, which had been so augmented that each company consisted of sixty-four men, exclusive of commissioned officers.
