in order to avoid the appearance of weakness. Amadas and his men burnt down the entire town and its crops, sending the natives fleeing. Manteo arranged a meeting for Grenville and Lane with Granganimeo, to provide land for the English settlement on Roanoke Island. Both sides agreed that the island was strategically located for access to the ocean and to avoid detection from Spanish patrols. Lane began construction of a fort on the north side of the island. There are no surviving renderings of the Roanoke fort, but it was likely similar in structure to the one at Mosquetal. Grenville set sail for England aboard the Tiger on August 25, 1585. Days later, in Bermuda, Grenville raided a large Spanish galleon, the Santa Maria de San Vicente, which had become separated from the rest of its fleet. The merchant ship, which Grenville took back to England as a prize, was loaded with enough treasure to make the entire Roanoke expedition profitable, spurring excitement in Queen Elizabeth's court about Raleigh's colonisation efforts. The Roebuck left Roanoke on September 8, 1585, leaving behind one of the pinnaces under the command of Amadas. Records indicate 107 men remained with Lane at the colony, for a total population of 108. However, historians disagree as to whether White returned to England with Grenville, or spent the winter at Roanoke despite his absence from the list of colonists. Exploration Many of the colonists had joined the mission expecting to discover sources of gold and silver. When no such sources were located, these men became dispirited and decided the entire operation was a waste of their time. The English also researched where the local Native Americans obtained their copper, but ultimately never tracked the metal to its origin. The colonists spent the autumn of 1585 acquiring corn from the neighboring villages, to augment their limited supplies. The colony apparently obtained enough corn (along with venison, fish, and oysters) to sustain them through the winter. Little information survives, however, about what transpired at the colony between September 1585 and March 1586, making a full assessment of the winter impossible. The colonists most likely exhausted their English provisions and American corn by October, and the resulting monotony of their remaining food sources no doubt contributed to the men's low morale. Amadas spent the winter exploring Chesapeake Bay, traveling as far as Cape Henry and the James River. While there
