how did john smith improve conditions in jamestown?

John Smith improved conditions in Jamestown primarily by enforcing discipline and hard work among the colonists, repairing and strengthening the fort, and promoting farming and fishing to ensure food supply. He is known for his strict rule: "He that will not work shall not eat," which motivated settlers to contribute to the colony's survival. Under his leadership, the fort was expanded and fortified, a well was dug for fresh water, houses were built, and crops were planted, all of which helped save the struggling colony from early devastation. Additionally, Smith established trade and negotiations with the local Powhatan Confederacy, which provided crucial food supplies during times of scarcity. His leadership helped Jamestown survive harsh conditions, disease, and food shortages until more settlers and supplies arrived.
