Soon after arriving at Jamestown, the colonists were attacked by the Algonquian natives. Within a month, the colonists built a triangular-shaped, wooden wall to defend their small settlement, which consisted of a storehouse, church, and several houses. Disease, famine, and the on-going attacks from local tribes strained the new colony. Its only hope came from the colony's trade with the Powhatan natives. The Powhatans gave the colonists food in exchange for iron and copper tools. In time, the colonists abandoned their fort and moved the settlement further inland.
