Why did people die in jamestown?

There are several reasons why they died. When they landed they chose the worst area to settle and build a fort. The James River was a bad source for water because it was swampy and would back up. Disease took many of the 104 men within 6 months and the men didn't come to settle the land but look for gold and fortunes and didn't plant crops. If the 14,000 Native Americans living there had wanted them out all they had to do is attack the fort, but they didn't do that for over 20 years after the first men arrived. The Jamestown colony made many bad decisions and it cost them lives.
