June 25
Battle of the Little Bighorn
Lieutenant Colonel George Armstrong Custer and more than two hundred men of the 7th Cavalry were killed on June 25, 1876, after attacking a large encampment of Lakota Sioux, Northern Cheyenne, and Arapaho along Montana’s Little Bighorn River.
Summary
By the mid-1870s, U.S. government efforts to confine Lakota Sioux, Cheyenne, and Arapaho tribes to reservations clashed with tribal resistance to land loss in the northern Plains. Lieutenant Colonel George Armstrong Custer led the 7th Cavalry Regiment in pursuit of a large Native village along the Little Bighorn River in Montana Territory. On June 25, 1876, Custer divided his forces and attacked the encampment of thousands of warriors led by Sitting Bull and Crazy Horse. The Native coalition overwhelmed Custer's immediate command of over 200 soldiers in fierce fighting that afternoon, resulting in their complete annihilation. The defeat stunned the U.S. public and intensified the Great Sioux War.
Context
In the decade after the Civil War, federal policy sought to confine Plains tribes to reservations while opening their former hunting grounds to miners, ranchers, and railroads. The 1868 Treaty of Fort Laramie had recognized Lakota control over the Black Hills and unceded Powder River country, yet the 1874 discovery of gold there brought thousands of prospectors onto lands the government had pledged to protect. Tensions rose as many Lakota, Cheyenne, and Arapaho bands rejected agency life and continued to hunt and camp freely.
By late 1875 the Interior Department ordered all non-reservation Indians to return to agencies by January 31, 1876, or be considered hostile. When Sitting Bull’s followers ignored the deadline, the War Department assumed control and planned a summer campaign involving three converging columns under Generals Alfred Terry, George Crook, and Colonel John Gibbon. The goal was to force the remaining free bands onto reservations and end resistance in the northern Plains.
Custer’s 7th Cavalry formed part of Terry’s Dakota Column, which departed Fort Abraham Lincoln in mid-May. Earlier clashes, including Crook’s fight at the Rosebud on June 17, had already alerted tribal leaders to the approaching troops and drawn additional warriors to a massive village moving along the Little Bighorn River.
What Happened
On the morning of June 25, Custer’s scouts reported a large village in the valley below the Wolf Mountains. Believing the inhabitants might scatter if not attacked immediately, Custer divided his roughly twelve companies into three battalions. Major Marcus Reno received orders to strike the southern end of the encampment, while Captain Frederick Benteen was sent with three companies to scout the left flank. Custer kept five companies under his direct command and moved north along the bluffs east of the river.
Reno’s assault met stiff resistance from hundreds of warriors and was driven back across the river into timber and then onto high ground, where his men dug in. Meanwhile Custer’s battalion encountered a growing counterattack led by Crazy Horse and other war leaders. Outnumbered and outflanked, the five companies were overrun in a running fight that left no survivors. Reno and Benteen, joined by the pack train, held a defensive perimeter on what became known as Reno Hill through the afternoon and night.
On June 26 the village began to break up and move upstream after scouts reported Terry’s main column approaching from the north. The combined Reno-Benteen force was relieved later that day. In all, 268 soldiers, civilians, and Indian scouts from the 7th Cavalry died; Native losses are estimated at sixty to one hundred warriors.
Aftermath
Eastern newspapers received word of the defeat in early July, producing shock and calls for decisive retaliation. Congress quickly authorized additional troops and funds, and the Army intensified operations through the remainder of 1876 and into 1877. Crook’s and Terry’s columns pursued the scattered bands, while Sitting Bull led a portion of his people into Canada.
Most Lakota and Cheyenne eventually returned to reservations or surrendered under pressure. The military campaigns that followed the battle effectively ended organized resistance in the northern Plains and accelerated the confinement of the tribes to agency lands.
Legacy
The fight along the Little Bighorn became a potent symbol of Native defense of homeland and of the limits of U.S. military power on the frontier. In popular memory it was long framed as “Custer’s Last Stand,” elevating the fallen officer to near-mythic status, while later scholarship and the battlefield’s interpretive programs have emphasized the perspectives of the Lakota, Cheyenne, and Arapaho participants.
Today Little Bighorn Battlefield National Monument preserves the ground and presents both military and tribal accounts, serving as a focal point for ongoing discussion of the American Indian Wars, treaty rights, and the contested narratives of western expansion.
Why It Matters
The battle became a symbol of Native resistance and U.S. military overreach, prompting escalated federal campaigns that ultimately forced many tribes onto reservations. It remains central to studies of the American Indian Wars and Native sovereignty struggles.
