By contrast, Chief Hancock had to deal with more numerous colonists encroaching on his community. They raided his villages and kidnapped people to sell into slavery. The colonists transported some Tuscarora to Pennsylvania to sell into slavery. Both groups of Tuscarora suffered substantial population losses after exposure to Eurasian infectious diseases endemic to Europeans. Both also suffered territorial encroachment. By 1711 Chief Hancock believed he had to attack the settlers to fight back. Chief Tom Blunt did not join him in the war.
