The first permanent French colony was founded in Quebec by: Samuel de Champlain Jean Baptiste de Bienville User: Why is Powhatan important to England's settlement attempts? He provided supplies to rescue Jamestown. He rescued John White from the Algonquins.
Weegy: 2.He provided supplies to rescue Jamestown User: Cabot started an English settlement along the coast of Newfoundland. True False User: Why did the Jamestown colony almost fail? The men were more interested in searching for gold than planting crops. The Indian tribes would not trade food and supplies. Weegy: Jamestown was a poor location for a settlement. The men dug wells for water, but the drinking water was bad. Also, the land was wet and had too many mosquitoes. Mosquitoes carry diseases and made the colonists sick. [ Also, the land was swampy and it was bad for crops and farming. After one year, about half the colonists had died of disease or starvation. The colonists had not bothered to plant or gather food for the winter. They had been too interested in looking for gold. Captain John Smith became leader of the Jamestown Colony. He saved the colony by making a rule that anyone who did not work did not eat. This made the colonists plant food, and build shelters and fences to protect themselves from attack. Captain John Smith maintained a peace with the nearby Algonquian Indians. At the time, almost 30 tribes of the Eastern Woodlands Indians lived in Virginia. The Indian tribes formed a confederation led by Chief Powhatan. One day, Captain John Smith was captured by the Indians. A legend says that Pocahontas, the chief's daughter, saved his life. ] User: Who helped save the Jamestown colony from destruction? Sir Walter Raleigh John Smith (More)
