In this context, Samuel Purchas wrote "Virginia's Verger" in 1625, asserting England's right to possess and exploit its North American claim. He argued that the natives, as a race, had forfeited their right to the land through bloodshed, citing the 1586 ambush of Grenville's garrison, an alleged attack on White's colonists, and the 1622 Jamestown massacre. Purchas offered no evidence for his claim about the 1587 colony except to state, "Powhatan confessed to Cap. Smith, that hee had beene at their slaughter, and had divers utensills of theirs to shew."
