Answer:
Signal from the Colonists
Step-by-step explanation:
In John White's narrative of the 1590 voyage to Virginia , before they could get to the place where they left planters, it was dark and they overshot the place by a quarter mile.
On getting to the North end of the Island, they saw the great fire. They rowed towards the fire and called out sounding trumpets in the hope that it was the colonists.
However, it was probably a fire started by lightning as the colonists were not there.
