Boone and his men were taken to Blackfish's town of Chillicothe. As was their custom, the Shawnees adopted some of the prisoners to replace fallen warriors. Boone was adopted into a Shawnee family at Chillicothe, perhaps into Blackfish's family, and given the name Sheltowee (Big Turtle). In March 1778, the Shawnees took the unadopted prisoners to Governor Hamilton in Detroit. Blackfish brought Boone along, though he refused Hamilton's offers to release Boone to the British. Hamilton gave Boone gifts, attempting to win his loyalty, while Boone continued to pretend that he intended to surrender Boonesborough. Boone returned with Blackfish to Chillicothe. On June 16, 1778, when he learned Blackfish was about to return to Boonesborough with a large force, Boone eluded his captors and raced home, covering the to Boonesborough in five days on horseback and, after his horse gave out, on foot. Biographer Robert Morgan calls Boone's escape and return "one of the great legends of frontier history."
