campaigns in Santo Domingo, Cartagena, and St. Augustine. During these raids, Drake had acquired refugees, slaves, and hardware with the intent of delivering them to Raleigh's colony. Upon learning of the colony's misfortunes, Drake agreed to leave behind four months of supplies and one of his ships, the Francis. However, a hurricane hit the Outer Banks, sweeping the Francis out to sea. After the storm, Lane persuaded his men to evacuate the colony, and Drake agreed to take them back to England. Manteo and an associate, Towaye, joined them. Three of Lane's colonists were left behind and never heard from again. Because the colony was abandoned, it is unclear what became of the slaves and refugees Drake had meant to place there.

A second Englishman was killed; the remaining nine retreated to the shore, and fled the island on their boat. They found their four
