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.
Pocahontas saved Jamestown because she saved the life of John Smith.

John Smith, a harsh and brutal ruler who forced the colonial "gentlemen" to work hard for the good of the colony, is generally said to have saved Jamestown.
John Smith is the leader who saved the Jamestown settlement from failure. By making everyone work in order to eat, he ensured that everyone was willing to pitch in for the common good.
