, a historical moment in the Great Sioux War of 1876-1877.
When the steamer Far West arrived at Fort Abraham Lincoln on July 5th, 1876, carrying wounded members of the 7th Cavalry, the news of the disaster at the Little Bighorn spread rapidly across the country. But the war with the Lakota Sioux and their Northern Cheyenne allies was far from over. In the weeks that followed, the conflict continued to unfold across the Northern Plains. The federal government's response came not only from the battlefield, but from the halls of Congress.
Warbonnet Creek — July 17th, 1876
Just twelve days after the Far West reached Fort Abraham Lincoln, a small but consequential skirmish took place in northwestern Nebraska along Warbonnet Creek located near the now abandoned settlement of Montrose.
Colonel Wesley Merritt and several companies of the 5th US Cavalry had been ordered north to join General George Crook's forces in Wyoming. Along the way, Merritt learned that a band of Northern Cheyenne, led by Little Wolf, had left the Red Cloud Agency and was attempting to travel north to join the Lakota and Cheyenne who had fought the U.S. Army at the battles of the Rosebud and Little Bighorn. Merritt moved quickly to intercept them.
On the morning of July 17th, the 5th Cavalry had much of its force concealed near the trail. A small group of Cheyenne warriors rode toward what appeared to be a vulnerable wagon train, only to discover that the soldiers were waiting for them. The resulting action was brief, but it became famous because of the encounter between U.S. Army scout William F. “Buffalo Bill” Cody and a Cheyenne warrior known as Yellow Hair.
During the ensuing skirmish, Cody killed Yellow Hair, later portraying the incident in his popular Wild West Shows across the country and even Europe. Over time, the event became heavily wrapped in the mythology surrounding Buffalo Bill and his exploits.
Congress Takes Action — August 15th, 1876
, August 15th, marks another significant moment in the story of the war. On this date, Congress passed the Indian Appropriations Act of 1876. Buried within the appropriations legislation was a provision aimed directly at the Lakota Sioux.
The act stated that no further appropriations for the subsistence of the Sioux would be made unless they agreed to cease hostilities and relinquish claims to lands outside the boundaries of the 1868 Great Sioux Reservation, plus the Black Hills, and granted rights-of-way across the reservation.
The legislation represented a dramatic escalation in the federal government's efforts to force the Lakota to surrender the Black Hills and other lands. The 1868 Fort Laramie Treaty had recognized the Black Hills as part of the Great Sioux Reservation, but the discovery of gold had brought miners and increasing pressure from settlers into the region.
The events of 1876 therefore cannot be understood solely through the battles of Rosebud or Little Bighorn. While soldiers pursued Lakota and Cheyenne bands across the Northern Plains, political and economic forces in Washington were simultaneously reshaping the future of the Great Sioux Reservation and the future's of the Lakota and Cheyenne people.
In the meantime, the war continued. From Warbonnet Creek to Slim Buttes, from the Yellowstone country to the reservation agencies, the summer and fall of 1876 and much of 1877 would bring more fighting, more military campaigns, and increasingly severe pressure on Lakota and Cheyenne communities.
The conflict was only beginning its next harsh chapter.
