The Edmeston brothers returned to England, but sent a number of settlers, likely including some Irish indentured servants, back to their estate.
In September 1778, a group of Native Americans who were allied with the British, mistakenly set Carr's house on fire and carried him and his wife to Canada through the Niagara region.
At least one account has stated that Carr was treated very poorly, having been forced to lie down in steams to allow his captors to use his body as a footbridge.
Carr's direct appeal for relief to William Edmeston, on the grounds of old age and a "State of absolute Penury", was equally without success.
Finally, however, a small piece of property was secured for him, and Carr remained in Otsego County until his death in 1804, when he was buried on John Tunnicliff's farm near Schuyler Lake.
