The Modoc War of 1872-1873: A Short History

A Small War in a Volcanic Basin

The Modoc War was one of the last and most studied of the conflicts between the United States and the Native nations of the West. It was fought by a small Modoc band, never more than about sixty fighters with their families, against a far larger force of U.S. Army soldiers and volunteers. It lasted from late 1872 into the summer of 1873, and it was fought across a stretch of lava beds south of Tule Lake in what is now the Oregon and California border country. What follows is a short, plain account of how the war came about, how it was fought, and what it cost the Modoc people.

The Causes: Removal and a Broken Reservation

The Modoc had lived for thousands of years in the basin around the Lost River, Tule Lake, and Lower Klamath Lake. It was their country, learned and adapted to over many generations. By the 1860s, settlers were moving through that country in growing numbers, and pressure built on the federal government to clear the Modoc from the land.

An 1864 treaty placed the Modoc, the Klamath, and the Yahooskin band of Northern Paiute together on the Klamath Reservation in Oregon. For the Modoc this meant leaving their own territory and living on land that belonged to the Klamath, with whom they had old tensions. The agency did little to ease those tensions or to provide what had been promised. Conditions were poor, and the arrangement was unworkable for many of the Modoc.

In 1870 the leader the settlers called Captain Jack, whose Modoc name was Kintpuash, led a group of Modoc off the reservation and back to the Lost River. He asked repeatedly, over the following years, for a small reservation in the Modoc's own country. The Indian Office refused. By 1872 the federal government had decided to return the Modoc to the Klamath Reservation by force if necessary.

The War Begins at Lost River

On November 29, 1872, the Army moved to bring the Modoc back. A confrontation at the Modoc camp on the Lost River turned into a firefight. People were killed on both sides, and in the chaos that followed, some Modoc men killed settlers around Tule Lake. Kintpuash and his band, with their families, withdrew south into the lava beds. From that point there was no turning back to a peaceful negotiation on the old terms. The Modoc War had begun.

Captain Jack's Stronghold

The Modoc retreated into a natural fortress in the lava beds, a maze of collapsed lava tubes, trenches, and ridges that the soldiers came to call Captain Jack's Stronghold. The Modoc knew the ground intimately. The Army did not. In the broken volcanic terrain, a small number of well-positioned defenders could hold off a much larger force, and they did.

In January 1873 the Army launched a major assault on the Stronghold under heavy fog. It failed badly. The soldiers suffered significant casualties and could not dislodge the Modoc, who held their ground without losing a single fighter in that first battle. The defense of the Stronghold remains one of the more remarkable small-unit stands in the military history of the period, and it bought the Modoc months inside the lava beds.

The Peace Tent and the Killing of General Canby

With the assault stalled, Washington sent a peace commission to negotiate a surrender. General E.R.S. Canby, commander of the Department of the Columbia, led the talks alongside the commissioners. The negotiations went on for weeks. Inside the Stronghold, the Modoc were divided. Some pressed for a settlement. Others believed, with reason, that surrender would lead to hangings, and they pushed for a different course.

On April 11, 1873, during a meeting at the peace tent, Kintpuash and several other Modoc killed General Canby and the commissioner Eleazar Thomas, and wounded Alfred Meacham. It was the only time in the history of the country's Indian wars that a general officer was killed. The act ended any prospect of a negotiated peace and brought down the full weight of the Army on the Modoc.

The End of the War

After Canby's death the Army renewed its campaign in force. A second assault eventually forced the Modoc out of the Stronghold. Short of water and supplies, the band scattered into the surrounding country. Through the late spring the Modoc fighters were pursued, divided, and worn down. Some surrendered. Others were captured. Kintpuash was taken at the start of June 1873, and with his capture the war was over.

A military commission tried Kintpuash and several others. He and three other men were sentenced to death and hanged at Fort Klamath on October 3, 1873. Two more had their sentences commuted to imprisonment.

The Aftermath for the Modoc

The punishment did not end with the executions. The federal government removed the surviving members of Kintpuash's band, more than one hundred and fifty people, far from their homeland to the Quapaw Agency in Indian Territory, in present-day Oklahoma. There they were strangers in a strange climate, and many died in the years that followed.

Decades later, in 1909, some of the Oklahoma Modoc were finally allowed to return to the Klamath Reservation. Others chose to remain in Oklahoma, where their descendants live today as the Modoc Nation. The Modoc people endured, in two places, carrying forward the memory of the homeland and of the war.

The Modoc War is often told as a frontier drama, with Kintpuash cast as the villain. The fuller history is harder and more honest. It is the story of a people defending their right to live in their own country, of negotiations that failed, and of a small band that held a vast army at bay in the lava beds before the cost came due. That is the war worth remembering, and worth telling carefully.
