They had been taken and were used as slave labor in native copper mining, and in short, everywhere John Smith went, he was stymied, as the people who had them would not give them up. They came close, but couldn't. Now, the investors of the Virginia Company were facing a backlash in England over treatment of the natives, a historian said, and the voyage's backers would not have liked hearing that they were outnumbered and the mission had failed. So a huge coverup was manufactured, they believe, one of the biggest in histroy....they lied, said all the colonists had been slaughtered by natives....which gave an excuse to genocide the Powhatan natives.
