What did Edward John Smith do?

He did NOT save Jamestown. He was only there a very few months and he lied about his contribution to the settlement in a book he wrote several years later. He also made up the story about Pocahontas and she died young so couldn't refute his story. The man who did save Jamestown was the husband of Pocahontas and gave tobacco seeds to the colony. That was John Rolfe.
