Captain John, a natural leader, took "control" over Jamestown. He made the men eat, by saying this:
"If any would not work, neither should he eat."
That really was motivation for the others. While he was looking for good, he was captured by Indians and had a great feast. After the feast, the Indians wanted to kill him by clobbering him to death. Then, Pocahontas has helped him by saving his life, and helped bring the town food, and help prevent "death, famine, and utter confusion."
