The Jamestown supply missions were a series of fleets (or sometimes individual ships) from 1607 to around 1611 that were dispatched from England by the London Company (also known as the Virginia Company of London) with the specific goal of initially establishing the company's presence and later specifically maintaining the English settlement of "James Fort" on present-day Jamestown Island. The supply missions also resulted in the colonization of Bermuda as a supply and way-point between the colony and England.
The Jamestown colonists initially chose the fort's location because it was favorable for defensive purposes. Although some of them did some farming, few of the original settlers were experienced farmers, and as hunters they quickly exhausted the area's supply of small game. To make matters worse, the most severe drought in 700 years occurred between 1606 and 1612. Consequently, the colonists quickly became dependent upon trade with the Native Americans and periodic supply from England for their survival. Captain Christopher Newport was tasked with the duty of leading the first three re-supply missions back to Jamestown. However, it was not until a fourth mission under Lord Thomas West that the settlement was finally able to establish both defensive and food security.
