Early Jamestown was plagued by disease, starvation, contaminated water, conflict with Indigenous peoples, and a severe drought that ranks among the worst in nearly 800 years. Of the 104 men and boys who stayed at the settlement in 1607, somewhere between 80 and 90 percent were dead by early 1610. The colony came remarkably close to total failure, and the reasons were interconnected.
Disease and Contaminated Water
The settlers chose one of the worst possible locations for their fort. Jamestown sat on swampy, low-lying ground along the James River, and the water supply was contaminated by both human waste and saltwater intrusion from the Chesapeake Bay. The river’s salinity shifted constantly depending on tides, storms, and rainfall, meaning the colonists could never count on fresh drinking water. The groundwater was no better: modern analysis of the Jamestown aquifer has found elevated levels of arsenic, iron, sulfur, and fecal bacteria.
Many colonists had carried typhoid and dysentery with them from England. Settlers at the time called dysentery “the bloody flux,” and it spread rapidly because no one understood basic sanitation. Their latrines contaminated the same water they were drinking. During the summer and autumn of 1607, illness tore through the colony. The combination of salt poisoning from brackish water and waterborne infections created a cycle of dehydration and disease that killed settlers faster than any single cause alone.
Extreme Drought and Food Shortages
Tree-ring data from Virginia reveal that the Jamestown settlers arrived at the start of the driest seven-year stretch the region had seen in 770 years. From 1606 to 1612, a prolonged drought reduced crop yields, dried up freshwater sources, and pushed saltwater further upriver into the colony’s drinking supply. This was not ordinary bad luck. The same type of analysis showed that the earlier Lost Colony at Roanoke had disappeared during the most extreme drought in 800 years. The pattern is clear: English colonists repeatedly tried to settle during periods of extraordinary environmental stress.
The drought made it nearly impossible for colonists to grow enough food, and it also reduced the surplus available from local Indigenous communities, increasing tension over resources.
The Starving Time of 1609 to 1610
The worst period came during the winter of 1609 to 1610, known as the Starving Time. Roughly 500 colonists were living at Jamestown when the crisis began. By spring, about 75 percent of them were dead from hunger and disease.
Several factors converged. A critical supply ship, the Sea Venture, carrying the colony’s new governor and badly needed provisions, wrecked on Bermuda and never arrived. The ongoing drought had already strained food supplies. And in November 1609, the Powhatan leader ordered what amounted to a siege of Jamestown, cutting off the colonists’ access to outside food sources. A party of about thirty colonists led by John Ratcliffe ventured out to trade for corn and were ambushed and killed. The siege lasted through the winter until early May 1610.
Conditions inside the fort became so desperate that colonists resorted to cannibalism. Archaeologists from the Smithsonian and Preservation Virginia confirmed this in 2013 after examining the skull and leg bone of a 14-year-old girl, nicknamed “Jane.” Her skull showed shallow chops to the forehead from a failed first attempt to crack it open, followed by deep, forceful blows from a small hatchet to the back of the head. Cut marks on her jaw indicated someone had used a knife to remove flesh from her face and throat. Researchers noted that the cuts showed “tentativeness, trial, and complete lack of experience in butchering,” reflecting pure desperation rather than any prior practice.
Conflict With the Powhatan Confederacy
Jamestown was built within the territory of the Paspahegh people, part of a larger political network led by the paramount chief Powhatan. Relations deteriorated quickly. The English colonists could not adequately feed themselves, so they pressured local Indigenous communities for food. This led to escalating conflicts along the James River that intensified in autumn 1609 and formally became the First Anglo-Powhatan War, lasting from 1609 to 1614.
The violence was brutal on both sides, though the English adopted tactics borrowed from England’s colonial wars in Ireland. Soldiers burned villages, destroyed crops, and killed women and children. In one documented incident, English soldiers threw captured children overboard and shot them in the water before later executing their mother. The Kecoughtan people, who had initially left the English alone, were attacked after colonists lured warriors to the riverbank by having a drummer imitate a traditional Powhatan greeting.
This ongoing warfare compounded every other problem the colony faced. It cut off potential trade for food, made it dangerous to venture outside the fort, and consumed energy and resources that could have gone toward building a self-sustaining settlement.
The Wrong People for a Survival Colony
The composition of the first settlers made survival harder than it needed to be. A significant portion of the original 104 colonists were classified as “gentlemen,” a social rank that meant they had no experience with manual labor, farming, or trades. The passenger lists from 1607 show gentleman after gentleman alongside a much smaller number of laborers and craftsmen. In the rigid class structure of early 17th-century England, gentlemen simply did not do physical work, and many refused to adapt even as the colony starved.
This imbalance meant fewer people were available to plant crops, build shelters, dig wells, or do the grinding daily labor that survival required. The Virginia Company, which funded the expedition, had prioritized finding gold and a passage to Asia over the practical needs of sustaining a settlement. The colony paid for that miscalculation in lives.
How These Problems Reinforced Each Other
No single factor explains Jamestown’s catastrophic early mortality. The drought reduced both food and freshwater. Contaminated water spread disease, which weakened the labor force. A weakened labor force couldn’t grow food or defend the fort. Hunger drove the colonists to pressure Indigenous neighbors, which led to conflict that further restricted food access. And when the one supply ship that might have stabilized the colony wrecked in the Atlantic, there was no safety net left. Each problem fed the others, creating a spiral that killed roughly nine out of every ten people who set foot in Jamestown during its first three years.
