The first American colony settled on a island in north Carolina. they brought along a native that joined their group. Suddenly they found one of their men killed. Was he sick? was he killed? That's what shook the devastating action upon the colony. So the colony moved out and fleed to the nearest safe spot they found.
After this chapter the colony went back for resources. They also went to carve their territory sign on a tree, but if any one found a cross on the tree that meant DANERR! So did the colony return? NOPE
What I believe is that the Indian who joined the group is a "spy" for the natives, he was probably was the killer of the colonies man. Based on my theory I also believed he carved the sign on the tree knowing the colony wont survive so when the colony try to leave that's when the natives attacked them on the boat .
