Were John Smith's goals the reason for Jamestown's success?

John Smith's Goals -----

• Encourage a policy for farming to replenishing food for the colony.
• Enforce a strict code pf discipline.
• Strengthen Defense.

John Smith is well known from his part in the Disney movie Pocahontas, but he is also known for his leadership in shaping the new world and the colony of Jamestown. Jamestown was a colony set up, at that time in 1607 for Englishmen and boys to go out and search the new world for gold, in hopes for coming up successful like the Spaniards in South America. 144 total people came over on the initial voyage to the New World, Virginia to be exact. Doing little farming since they were sent out to search for gold, the colony began to suffer as food diminished and the harsh winter struck the colonist along with malaria, a serious disease.
After the first year, 38 people were left from the original 144, then John Smith brings his leadership to save the colony from perishing. He was very strict and had the motto "Work or Starve", and anybody hearing those words would be smart to follow the motto as code. He also made it rule that every person had to spend four hours farming each day, which began to replenish the food. In 1609, John Smith had to return to England after a gun powder incident. He would never return to the colony.
History shows that John Smith was the reason for Jamestown's success due to the fact the goals he set out to accomplish improved the colony a full year leading up to his departure. The colony was on the verge of perishing and being executed by the Powhatan tribe. Smith becoming a subordinate chief in the tribe can be credited with keeping the Powhatan's from attacking the colony. And even after his departure he still promoted the further colonization of Virginia. He encourage more men and woman to follow and go to Virginia, convincing everyone that the new world was the "land of opportunity."
John Smith did receive another chance to return to the New World, but not Virginia, he made a successful voyage to Maine and the Massachusetts Bay area, and he named it New England. It would be his last successful trip to the New World.
