Why did Frethorne say that American Indians were such a threat? * All the settlers were unhappy The settlers were weakened by illness Many settlers had returned to England Many settlers had been enslaved

The settlers were weakened by illness

Explanation:

Richard Frethorne was an indentured servant serving in the colony of Virginia during its earlier days. In a letter to his parent, he employed them to send for him or at least send him some provisions because conditions in the settlement were pitiful.

He mentioned how they lived in constant fear of Indians who they keep fighting with. He was worried that they were in grave danger though because the settlers were afflicted by sickness and some had already died thus weakening their number resulting in less resistance to the Indians.
