The air in the longhouse was thick with the smoke of fires and the desperate gasps of the dying, but for Father Isaac Jogues, the true poison was the fear that had gripped the Huron nation. Just days after his arrival in the fall of 1636, the young Jesuit found himself not as a triumphant bringer of salvation, but as a victim of a mysterious and violent plague that was sweeping through the villages of present-day Ontario. The influenza that struck Huronia that autumn was more than a biological catastrophe; it was a cultural collision point where European medicine, native superstition, and the very will to survive clashed in a desperate struggle for the souls and bodies of an entire people.

As the fever consumed the French missionaries and the native population alike, the Hurons turned not to the priests’ God, but to their sorcerers, who claimed the devil himself had revealed the cure, leading to a spiral of ritual, accusation, and terror that threatened to end in massacre.

The epidemic began its deadly work almost immediately after Father Jogues stepped from his canoe on September 11th, 1636, exhausted from a nineteen-day journey. Within days, the initial euphoria of his arrival faded into a “deadening lassitude,” and by the following Wednesday, he was in the throes of a burning fever. He was not alone.

The workman Mathurin arrived at the mission of Ihonatiria, abandoned by his Huron guides and shaking with the same debilitating sickness. The small French outpost, a single cabin in the wilderness, quickly became a hospital ward with no doctors and no remedies. Father Le Mercier, who had joked the previous year about having no patients to practice on, found himself the sole infirmarian for a growing number of stricken men, including the young lad Jean and the engagé Dominique.

The French had only purges and a desperate knowledge of bloodletting, a procedure none of them had ever performed, to combat an illness they did not understand.

The situation in the French cabin reached a critical point when Father Jogues, bleeding from the nose and racked by a violent cough, appeared to be on the verge of death. With the priests terrified to use a lancet on their brother, a remarkable decision was made: the patient would operate on himself. “He had bled one of the Indians on the journey,” the account reads, and believed he could do it on himself.

Shaking with illness, Jogues took the lancet and made the cut, watching his own blood pour into the receptacle. The self-administered surgery, a brutal gamble in the absence of any other option, seemed to work. The fever abated, but the crisis was far from over.

One by one, the other missionaries collapsed, including Father Chastelain and Father Garnier, who had concealed his own sickness to help the others. The cabin was filled with the moans of the sick, and the air was thick with the smoke that the patients desperately needed to avoid.

While the French struggled with their limited and often harmful medical practices, the Huron response to the plague was far more dramatic and, in the eyes of the missionaries, diabolical. The Hurons did not see a virus; they saw a malevolent spirit that had to be driven out. As the death toll rose in villages like Ossossané and Onentisati, hope turned to the sorcerers, or Arendiwans, who rose up with claims of immense supernatural power.

The most prominent was Taronhiawagon, a hunchback who declared, “I am not like other men. I am a demon.” He prescribed the game of lacrosse as a cure, and when the disease only worsened, he blamed the people for failing him.

Other sorcerers demanded gifts, staged ritual dances, and blew violently on the sick to expel the evil spirits. They held “sweats” in steaming tents, invoked demons in clouds of tobacco smoke, and interpreted the delirious dreams of the dying as commands that had to be obeyed, no matter how impossible or tragic.

The rituals often made the patients worse. Le Mercier described the “Ihou Tarohi” feasts, where participants were forced to eat until they vomited, and the “witches’ vigils” where men passed burning embers over the stomachs of the sick. The constant dancing, chanting, and howling in the crowded longhouses created a cacophony that deprived the sick of any rest.

While the French tried to enforce quiet in their cabin, the Hurons believed that noise and movement were the only ways to frighten away the demon of disease. This fundamental misunderstanding of basic care likely contributed to the high mortality rate. The Hurons, in their desperate attempt to save their people, were unknowingly hastening their deaths through exhaustion and dehydration, while the French were doing little better with their bloodletting, a practice that would later be discredited by the scientific community.

As the epidemic raged, the initial fear of the disease morphed into a more dangerous threat: the fear of the French themselves. The sorcerers, seeing their authority challenged by the black robes, began to spread rumors that the missionaries were the cause of the plague. They claimed the French were poisoners, that the broth they cooked was laced with death, and that the water they poured on the heads of the dying during baptism was a curse.

“The sickness was a huge poisoned cloak,” one sorcerer claimed, sweeping down from the direction whence the black robes arrived. The Hurons, watching the French administer their strange remedies and seeing that many of the baptized died soon after, began to believe these accusations. The priests, who had come to save souls, were now viewed as harbingers of death, and the talk turned to massacre.

Father de Brébeuf, the superior of the mission, fought back with a combination of diplomacy and bribery. He held a feast of deer meat and distributed 400 wampum beads, hatchets, and a moose skin to the chiefs of Ihonatiria, convincing them to make a vow to build a chapel if the God of the black robes stopped the plague. The vow was short-lived.

The next day, the same men donned their masks and chanted their ritual dances. The missionaries, for their part, took their own vows, offering masses to the Virgin Mary and Saint Joseph. They traveled to other villages, like Wenrio and Ossossané, extracting promises of conversion in exchange for divine relief.

In Ossossané, a chief named Aion publicly proclaimed that the people took God as their master, renounced their dreams, and would build a cabin in his honor. But these promises were made out of terror, not faith, and they crumbled as quickly as the disease persisted.

The hostility reached a fever pitch in January 1637. A chief named Taratande, his family stricken by the disease, hurled burning sticks at the priests and threatened to split the head of the first Frenchman he met. A plot was concocted to massacre all the French missionaries, and the priests knew it.

“Even the children spoke of us only as persons who were soon to have our heads split,” Le Mercier reported. The crisis was only averted by the swift hand of death, which took Taratande himself. His death, which the Hurons saw as a sign of the black robes’ power, terrified the other chiefs, who quickly repented and begged the priests for forgiveness.

The missionaries, though they had escaped death, were living on a knife’s edge, their survival dependent on the whims of a terrified and superstitious population.

The most dramatic confrontation came in the village of Ossossané, where a new sorcerer, Tearen Hignouan, had risen to prominence. He had fasted for ten days in a divining cabin and claimed to have learned the cure for the plague from the demons themselves. He sent his disciple, Saou Serinnon, to the village to banish the sickness.

De Brébeuf and Jogues, arriving at the same time, chose to stay in the very cabin where the great feast was to be held. That night, they witnessed a terrifying spectacle. A chief climbed onto a beam and cried out an invocation to the demon, begging it to leave the town and carry the sickness to their enemies.

The men of the village, almost naked, danced and chanted in a frenzy, beating drums and swaying in unison, until the sorcerer returned with a turkey wing and a kettle of “mystic water.” He passed down the lines, giving each man a few drops, and the people were enraptured, believing the demon had heard them and would fly away with the disease.

The sorcerer’s cure was a failure. The sick remained sick, and some died. When Saou Serinnon ordered the sick to be carried to him, a few died in the process.

The people’s faith in him shattered, and he fled the village, his delegates throwing away their turkey wings and renouncing their status as sorcerers, knowing that the penalty for failure was a split skull. In the aftermath of this failed ritual, the missionaries found a small opening. They were able to baptize a few dying souls, including a young brave whose relatives had guarded him from the priests until the moment of his death.

The epidemic, which had been a source of immense suffering, had also proven to be a powerful tool for conversion, as the Hurons, disillusioned with their own medicine men, turned in desperation to the God of the black robes who seemed to offer a different kind of hope.

The influenza of 1636-1637 was a watershed moment in the history of New France. It exposed the profound vulnerability of both the European colonizers and the native peoples to a disease neither could understand or treat. The French, with their bloodletting and broths, were practicing a medicine that was often as harmful as the disease itself.

The Hurons, with their rituals and feasts, were actively worsening the condition of their sick. The epidemic also revealed the deep cultural chasm between the two groups. The French saw a physical illness that required rest and nourishment; the Hurons saw a spiritual attack that required supernatural intervention.

This fundamental difference in worldview led to suspicion, fear, and ultimately, violence. The missionaries were nearly killed, not by the disease, but by the people they had come to save, who blamed them for the very pestilence that was decimating their communities.

The legacy of this outbreak is complex. It is a story of a biological catastrophe that killed thousands, but it is also a story of how fear and superstition can be as deadly as any virus. The Huron reliance on sorcerers, who prescribed exhausting rituals and dangerous feasts, likely increased the mortality rate.

The French reliance on bloodletting, which weakened already dehydrated patients, likely did the same. In the end, the epidemic served as a catalyst for the spread of Christianity. As the sorcerers failed and died, their credibility was destroyed, and the Hurons, in their desperation, were more willing to listen to the black robes who offered a different path to salvation.

The story of the 1636 influenza is not just a tale of disease; it is a stark illustration of how a society responds to an existential crisis, and how the clash of cultures can be as deadly as any plague. The missionaries survived, but the Huron world was forever changed, weakened by disease and fractured by the very beliefs they had clung to for survival.
