At Jamestown, a drought earlier in 1609 during the normal growing season had left the fields of the colonists of Virginia barren. Combined with the lack of trade with the Native Americans, and the failure of the Third Supply to arrive with expected supplies, the colony found itself with far too little food for the winter. With the new arrivals, there were many more mouths to feed. There are few records of the hardships the colonists experienced in Virginia that winter. Arms and valuable work tools were traded to the Powhatans for a pittance in food. Houses were used as firewood. Archaeologists have found evidence that they ate cats, dogs, horses, and rats. Cannibalism has been confirmed to have occurred in at least one case; the remains of a teenage girl of about fourteen years of age has been forensically analyzed and shown to have telltale marks consistent with butchering meat. A scientist has suggested another sinister possibility: arsenic poisoning.
