Previous to his capture he had been engaged in the Battles of White Plains, Germantown, Brandywine and Stony Point. He was one of the fifty who composed the “forlorn hope,” led by Mad Anthony Wayne at Stony Point, who met within the fort. He was at West Point and witnessed the execution of the unfortunate Major Andre. At the time of the ambuscade Captain Boyd was wounded during the skirmish, but after his capture and in spite of his wounds, he made a desperate effort to escape by running, but was pursued and received three terrible gashes in his head with a tomahawk when he was re-captured. The Indians immediately struck across the country, reaching the West Branch of the Susquehanna near the mouth of the Sinnemahoning Creek. They also had another prisoner named Ross, who was wounded even more severely than Boyd, and could travel no farther. He was fastened to a stake, with his arms tied behind his back; his body was cut with sharp points and pitch-pine splinters stuck into the incisions; the fire was lighted and the savages danced around him in fiendish glee. His tortures were terrible before death relieved him. During this tragic scene Captain Boyd, faint from the loss of blood, was tied to a small oak sapling, in such a position that he could not refrain from being a silent spectator of the horrible scene; realizing that he was soon to suffer the same tortures. He summoned up all his courage and resigned himself to his fate. Certainly his thoughts must have reminded him of the sufferings of his heroic brother only two years before, almost in the same manner. While the incarnate fiends were making preparations to torture him to death by inches, he sang a pretty Masonic song, with a plaintive air which attracted their attention and they listened to it closely until it was finished. At this critical moment an old squaw came up and claimed him for her son. The Indians did not interfere and she immediately dressed his wounds and attended to his comfort, carefully guarding him during their journey to Canada. This old squaw accompanied Captain Boyd to Quebec, where he was placed in a hospital and attended by an English surgeon. When he recovered he was turned out on the street without a penny or a friend. He found a Masonic Inn and made himself known to the proprietor who cared for him until he was exchanged. The old squaw who befriended him belonged to the Oneida tribe. Captain Boyd remembered her kindly as one of his best friends and frequently sent her presents of money and trinkets. On one occasion he made a journey north to visit her in her aboriginal home and personally thank her for saving his life. Captain Boyd, in partnership with Colonel William Wilson, operated a mill on Chillisquaque Creek, Northumberland County, for many years. He was one of the surviving officers who enjoyed the provisions of the act of Congress, May, 1828. He was a delegate to the convention which ratified the Federal Constitution December 12, 1787.
