The colony at Jamestown seemed doomed to meet the same fate as the Roanoke Colony and the Popham Colony, two earlier failed English attempts to settle in North America, unless there was a major relief effort, despite the delivery of supplies in 1608 on the First and Second Supply missions of Captain Christopher Newport. Yet the investors of the London Company expected to reap rewards from their speculative investments. With the Second Supply, they expressed their frustrations and made demands upon the leaders of Jamestown in written form. They specifically demanded that the colonists send commodities sufficient to pay the cost of the voyage, a lump of gold, assurance that they had found the South Sea, and one member of the lost Roanoke Colony.
