Genville decided to leave some men to start a colony at the north end of Roanoke Island. He did this even though they did not have a lot of food and the Croatans were angry about Aquascogoc. Ralph Lane and 107 men were left on Roanoke Island. Grenville promised to return in April 1586 with more men and supplies. Lane and his men left for Roanoke on 17 August 1585. Lane built a small fort on Roanoke Island and explored some of the area. There are no pictures of the Roanoke fort. It was probably a lot like Fort Elizabeth on Guayanilla Bay, Puerto Rico.
