What survival strategy is believed to have been employed by the Lost Colonists of Roanoke, as suggested by John White's accounts and the evidence left behind?

The Lost Colonists of Roanoke are thought to have used a survival strategy of integrating with local Native American tribes. John White's accounts suggest that they may have sought help from nearby tribes after facing hardships like food shortages. The evidence left behind, such as the word "CROATOAN" carved into a tree, hints that they might have moved to Croatoan Island, where they could find support. This idea shows that instead of trying to survive alone, they may have recognized the importance of forming relationships with the people already living in the area. For example, if a group of settlers ran out of food, they might have traded tools or goods with Native Americans in exchange for food or shelter.
