Fremont at Klamath Lake: The 1846 Massacre

The first man died with an axe in his skull. It was the night of May 9, 1846, on the eastern shore of Upper Klamath Lake, and Basil Lajeunesse, a trapper who had been with John C. Fremont across two earlier expeditions, never woke up. Kit Carson heard the blow land in the dark, sat up, and saw his friend in the firelight. By the time the camp came awake and drove the attackers off, two more of Fremont's men were dead. It was the first time the expedition had lost anyone to an attack, and the men who survived spent the rest of the night with their rifles, waiting for dawn.

What happened over the next few days is the subject of this piece. It is also one of the corners of the record that the novel Enos works inside. The killings at Klamath Lake are not a footnote to the conquest of California. They are one of its first hinges, and they were brutal in a way the official accounts tend to round off.

Gillespie and the dispatch

Fremont had no orders to be at war with anyone in the spring of 1846. His third expedition was, on paper, a survey. He had already worn out his welcome with Mexican authorities in California and had turned north into Oregon when a Marine lieutenant named Archibald Gillespie caught up with him near the lake, around May 8 or 9, having tracked him for weeks. Gillespie carried dispatches: a packet from Senator Thomas Hart Benton, who was Fremont's father-in-law, and word from the Polk administration in Washington. He had memorized other instructions and burned them.

This is the first place the record goes soft. We do not know, in any reliable way, what Gillespie's orders actually authorized. Historians have argued the point for more than a century. Some read the dispatch as little more than family news and a warning that war with Mexico was near. Others believe Gillespie carried an implicit license to take aggressive action in California, and that Fremont chose to read it that way. The documents that would settle it were destroyed or never written down. What is certain is that within hours of the meeting, men started dying.

The night attack

Fremont read his letters by the fire and, for whatever reason, did not post a watch. Late that night a party of warriors — most accounts say fifteen to twenty — came into the camp. Lajeunesse was killed first. A Delaware (Lenape) man the records call Crane got to his feet, leveled his rifle, and it misfired; he was hit by four arrows and died where he stood. A third man was killed, and another Delaware was wounded. The sources do not even agree cleanly on the count: some say two killed that night, some say three, and the name of the third man drifts between accounts.

The expedition blamed the Klamath. It is worth being honest that they may have had the wrong people. A number of historians argue the attackers were more likely Modoc, from bands to the south and east, and that the Klamath who paid for it had little or nothing to do with the raid. The men in Fremont's camp were in no condition to make that distinction, and they did not try.

The reprisal at Dokdokwas

Carson led the answer. Within a day or two, Fremont sent a party — roughly ten men, several of them Delaware scouts — against a Klamath fishing village near the mouth of the Williamson River, where it runs into the lake. The village is usually identified as Dokdokwas. The men hit it at dawn, killed the people they found there, and burned the lodges and the wooden racks hung with the winter's drying fish. The official figure is fourteen killed. Historians who have looked at it closely think the real number was higher, and that women and children were among the dead.

Carson did not hide what it was. In his own telling, the village was punished, and the burning of it he remembered as a spectacle. The Oregon Historical Project quotes his recollection plainly:

It was a beautiful sight.

The dates here are also unsettled. Some sources put the reprisal on May 10, others on May 12, and the difference of a day or two has never been firmly resolved. The shape of it is not in doubt. A camp lost three men to a night raid, and a village that may have had nothing to do with that raid lost far more, along with the food it needed to get through the year.

There is a smaller scene the histories like to keep, because it is the kind of thing that makes a legend. In the fighting around the village, a warrior had Carson in his sights, Carson's gun misfired again, and Fremont rode the man down with his horse before the arrow could fly. Fremont saved Carson's life. He also, afterward, praised Carson's work in the campaign without reservation, calling him cool and brave and of good judgment. The two men understood the week as a success.

Why Klamath Lake matters

Search for Fremont Klamath Lake or the Klamath Lake massacre 1846 and you will find the night attack told and retold, usually from the camp's side, with Lajeunesse's death and Carson's grief at the center of it. The retelling of the reprisal is thinner. That imbalance is the point. The expedition's losses were three men in their sleep, and they have names that survive. The Klamath dead were more numerous and are mostly nameless, and their winter stores went up with their houses.

From the lake, Fremont turned south. By June he was back in California's Sacramento Valley, and within weeks the Bear Flag Revolt and the American seizure of the province were under way. The thread runs straight from the burning racks at the Williamson River to the conquest, and the same men carried it. If you want the next link, the reprisal at the lake feeds directly into Kit Carson and the conquest of California, and the question of who authorized what catches up with Fremont himself at his later court-martial. The phrase Kit Carson Klamath belongs in that longer story, not apart from it.

What the record will not give you is the view from inside the village, or from the Delaware scouts riding for a government that was not theirs either, or from the people who watched the column come and go and understood, before anyone in Washington did, what was arriving. That is the gap the novel works in. Enos stands in that gap — a witness placed where the documents fall silent. The history above is the history; the novel keeps the line between them clear, and only goes where the paper stops.
