Section 3: Smallpox Epidemic of 1837
Smallpox epidemics had struck the tribes of the Upper Missouri at least twice before the terrible epidemic of 1837. The earlier epidemics of 1781 and 1801 took the lives of thousands of Mandans, Hidatsas, and Arikaras and forced them to move north to re-build their villages near the mouth of the Knife River. However, not long after the earthlodge villages became established on the Knife, they experienced the worst smallpox epidemic ever.
Fort Clark was a fur-trading post that had been built in 1823 just a few miles south of the mouth of the Knife River on the west bank of the Missouri River. One-quarter mile from the fort was the Mandan village of Mitu'tahakto's (meh TOOT ah hahnk tosh). Within 15 miles of the post were several more Mandan, Arikara, and Hidatsa villages. Earlier epidemics and inter-tribal conflict had forced the earthlodge peoples north to the Knife River. The Yanktonais, Crows, Assiniboines and other tribes traveled to Fort Clark bringing buffalo robes and furs to trade for tobacco, guns, cloth, and other goods. Fort Clark was a busy, densely populated center of international trade.
On June 18, 1837, the steamboat St. Peters approached Fort Clark. In addition to supplies, the St. Peters brought Andrew Jackson Chardon, the two-year-old son of Fort Clark’s superintendent, Francis Chardon. Chardon met the boat some 30 miles downstream. He removed his son from the boat and heard the news that people on the boat were infected with smallpox.
When the steamboat landed at Fort Clark, people came and went from the boat to the fort and the villages. Workers from the boat and the post unloaded goods and loaded bales of furs. All of the activity took place in less than 24 hours amid a “frolick” of singing and dancing and celebration. Once loaded, the St. Peters headed upstream to Fort Union carrying the deadly virus.
On July 14, 1837, Chardon noted in his journal that a Mandan man had died of smallpox in the village. (See Document 2.) Chardon knew that smallpox would become an epidemic and that many more would die, but the extent of the epidemic stunned him. He recorded the deaths of important village leaders including the highly-respected second chief of the Mandans, Four Bears. He heard, probably second-hand, the death-speech of Four Bears (See Document 2, entry for July 30.) and recorded it in his journal.
Chardon was unable to keep track of the number of deaths: “they die so fast that it is impossible,” he wrote. Survivors swore revenge against Chardon for bringing death to their villages. There were murders and threats of murder as the deeply despairing Mandans tried to avenge the deaths of their families and friends. Some people, sick with smallpox or feeling desperate from the loss of every member of their family, committed suicide. Suicide was unknown among the Mandans and Hidatsas before the epidemic.
Before the disease reached the post, Chardon sent his oldest son downriver to Fort Pierre. The boy was sent on to his grandparents’ home in Pennsylvania. The younger son, Andrew Jackson, remained with Chardon (the boy’s mother had died in April before the epidemic). When the disease finally penetrated the walls of the fort, Andrew Jackson sickened and died as did many other young children of the post employees.
When the disease reached Fort Union, more people, both Indians and non-Indians, were exposed and suffered. The superintendent at Fort Union tried to inoculate as many people as he could. Many tribes fled the area and probably saved many lives in doing so. The disease however, continued to spread across the northern Great Plains where the Indians had been denied access to the 1832 federal vaccination program.
The Mandan people suffered the greatest losses in the epidemic. Frequent, close contact among the people of the villages and the fur trade post helped to spread the disease quickly. About 2,000 Mandans lived in the Knife River villages in the spring of 1837. By October, 138 people remained alive. The survivors moved from the village at Fort Clark to other villages. The Arikaras, who had lost perhaps two-thirds of their population, moved into Mitu'tahakto's. They harvested the Mandans’ garden crops that year and remained in the village near Fort Clark.
Document 2. Smallpox at Fort Clark, 1837
In 1837, an outbreak of smallpox on the Upper Missouri River killed approximately 90 percent of all Mandans and one-half of the Arikaras (“Rees”) and Hidatsas (“Gros Ventres”). Most of these people lived in villages near the American Fur Company trading post, Fort Clark. The density of population and the constant travel to hunt and trade helped to spread the disease. The superintendent at Fort Clark was Francis A. Chardon. Daily entries in his post journal tell of the spread of the smallpox epidemic.
As people faced overwhelming loss, they sought revenge on Chardon. They legitimately blamed the white traders for bringing the disease among them. Some tried to kill Chardon, but he kept his men on alert to prevent an attack on himself or on the fort. Chardon was able to protect himself and his fort from attack, but the disease took the lives of his youngest son and many others living in the post.
The loss of loved ones and friends caused a great deal of despair. In some cases, Mandans or Hidatsas committed suicide. Chardon notes these suicides because, before the epidemic, suicide was almost unknown among the three tribes. Suicide was a sign of how deeply they felt the loss of their families and friends.
Chardon’s journal reveals how daily life was interrupted by the epidemic. The survivors would need meat and crops to get through the coming winter, but there were few people healthy enough to do the work. Chardon did not have enough workers to get hay and winter firewood supplies into the post. The gardens of the Mandans and Hidatsas suffered from heat and drought, and there were few healthy women to manage the harvest. In addition, the Yanktonais (Sioux) threatened and attacked the weakened villages.
Chardon wrote that some elderly Mandans and Hidatsas had survived the 1837 outbreak because they had had the disease in “Old times.” These elders had been exposed to smallpox in 1801 or perhaps as early as 1781. They survived in 1837 because once they had the disease, they were immune.
These journal entries have been edited for easier reading, though much of the original spelling remains. You will find some terms such as “squaw” which were in common use in Chardon’s day. The word “squaw” is used today only in historical documents.

Jonca started back immediately. The War Party of Rees and Mandans that left here the 26th of June, all came back to day, haveing Killed seven Sioux, Men, Women and children, two Lodges that were camped at the Mouth of White River.

Monday 16 — Several Rees that has been liveing with the Sioux, arrived to day — report that the Small Pox has broke Out amongst them. . .
Why is this important? The Mandans lost a significant part of their population in 1837. War leaders, spiritual leaders, mothers, fathers, and children died. The tribe was so weakened they could not hunt or harvest their gardens to prepare for winter; they could not defend themselves against attack. Other tribes on the northern Great Plains also suffered terrible losses. Smallpox returned to the Northern Great plains in 1851, again leaving survivors devastated.
Although the traders at Fort Clark and Fort Union knew beyond a doubt that smallpox would have a devastating effect on the Indians of the region, they had few resources with which to slow the outbreak. Had the captain of the St. Peters accepted advice to put the sick man off the boat, the epidemic might have been more limited in its effects. The captain chose to follow his business plan to deliver goods and pick up furs and return quickly to St. Louis. His choice had deadly consequences for his company’s business partners-the people of the northern Great Plains.
