Colonists in Jamestown, Virginia held a thanksgiving prayer service after English supply ships arrived with food. The harsh winter of 1609-1610 generated a famine that decimated the settlers. The group was reduced from 490 members to only 60 survivors who were forced to dire measures such as eating their horses. The colonial celebration which followed the arrival of the ships with food has also been considered the "first Thanksgiving." Architectural Remains in Jamestown, Virginia.
