When The colonists arrived at Roanoke they had little supplies. Sir Richard Grenville left 100 men on Roanoke and went back to get some more supplies. When John White and company arrived at Roanoke on July 22nd 1587 he saw the fort demolished and only the bones of one man. John Whit went back to England to get supplies for a trip he intended to last six to eight months.
The settlers tried to set up a colony and the forts got destroyed so then John White found the bones of one person. Then they decided to go to Roanoke and tried to settle on iy, but they had to turn back because of a storm.
John white leaves Roanoke because the people he left went to Croaton becuase there was no more food and they put CROATON on a trre like John White said to do. There was no vross found on a tree so they robably didn't leave because of danger.
