The Sand Creek Massacre (also known as the Chivington Massacre, the Battle of Sand Creek or the Massacre of Cheyenne Indians) was a massacre of Cheyenne and Arapaho people by the U.S. Army in the American Indian Wars that occurred on November 29, 1864, when a 675-man force of Colorado U.S. Volunteer Cavalry  under the command of U.S. Army Colonel John Chivington attacked and destroyed a village of Cheyenne and Arapaho people in southeastern Colorado Territory,  killing and mutilating an estimated 70–500 Native Americans, about two-thirds of whom were women and children. The location has been designated the Sand Creek Massacre National Historic Site and is administered by the National Park Service.
By the terms of the 1851 Treaty of Fort Laramie between the United States and seven Indian nations, including the Cheyenne and Arapaho,  the United States recognized that the Cheyenne and Arapaho held a vast territory encompassing the lands between the North Platte River and the Arkansas River, and eastward from the Rocky Mountains to western Kansas. This area included present-day southeastern Wyoming, southwestern Nebraska, most of eastern Colorado, and the westernmost portions of Kansas. 
In November 1858, however, the discovery of gold in the Rocky Mountains in Colorado,  then part of the Kansas Territory,  brought on the Pikes Peak Gold Rush. Immigrants flooded across Cheyenne and Arapaho lands. They competed for resources, and some settlers tried to stay.  Colorado territorial officials pressured federal authorities to redefine the extent of Indian lands in the territory,  and in the fall of 1860, A.B. Greenwood, Commissioner of Indian Affairs, arrived at Bent's New Fort, along the Arkansas River, to negotiate a new treaty. 
On February 18, 1861, six chiefs of the Southern Cheyenne and four of the Arapaho signed the Treaty of Fort Wise with the United States,  in which they ceded most of the lands designated to them by the Fort Laramie treaty.  The Cheyenne chiefs included Black Kettle, White Antelope (Vó'kaa'e Ohvó'komaestse),  Lean Bear, Little Wolf, and Tall Bear; the Arapaho chiefs included Little Raven, Storm, Shave-Head, Big Mouth, and Niwot, or Left Hand. 
The new reserve, less than 1/13th the size of the territory recognized in the 1851 treaty,  was located in eastern Colorado,  between the Arkansas River and Sand Creek.  Most bands of the Cheyenne, including the Dog Soldiers, a militaristic band of Cheyenne and Lakota that had originated in the late 1830s, were angry at the chiefs who had signed the treaty. They disavowed the treaty – which never received the blessing of the Council of 44, the supreme tribal authority – and refused to abide by its constraints.  They continued to live and hunt in the bison-rich lands of eastern Colorado and western Kansas, and became increasingly belligerent over the tide of white migration across their lands. Tensions were high, particularly in the Smoky Hill River country of Kansas, along which whites had opened a new trail to the gold fields.  Cheyenne who opposed the treaty said it had been signed by a small minority of the chiefs without the consent or approval of the rest of the tribe, that the signatories had not understood what they signed, and that they had been bribed to sign by a large distribution of gifts. Officials took the position that Indians who refused to abide by it were hostile and planning a war. 
The beginning of the American Civil War, in 1861, led to the organization of military forces in Colorado Territory. In March 1862, the Colorado volunteers defeated a Confederate Army from Texas in the Battle of Glorieta Pass, New Mexico by destroying their supply wagons, forcing them to retreat. The Confederates returned to Texas, and the First Regiment of Colorado Volunteers returned to Colorado Territory. They were then mounted as a home guard under the command of Colonel John Chivington. Chivington and Colorado territorial governor John Evans adopted a hard line against Indians, whom settlers accused of stealing livestock. Without any declaration of war, in April 1864, Colorado soldiers began attacking and destroying a number of Cheyenne camps, the largest of which included about 70 lodges, about 10% of the housing capacity of the entire Cheyenne nation.  On May 16, 1864, a detachment under Lieutenant George S. Eayre crossed into Kansas and encountered Cheyenne in their summer buffalo-hunting camp at Big Bushes, near the Smoky Hill River. Cheyenne chiefs Lean Bear and Star approached the soldiers to signal their peaceful intent, but they were shot down by Eayre's troops.  This incident touched off a war of retaliation by the Cheyenne in Kansas. 
Damn any man who sympathizes with Indians! ... I have come to kill Indians, and believe it is right and honorable to use any means under God's heaven to kill Indians. ... Kill and scalp all, big and little; nits make lice.
As the conflict between the Indians and settlers and soldiers in Colorado continued, many of the Cheyenne and Arapaho, including bands under Cheyenne chiefs Black Kettle and White Antelope, were resigned to negotiating a peace, despite pressures from the soldiers and settlers. In July 1864, Colorado governor John Evans sent a circular to the Plains Indians, inviting those who were friendly to go to a place of safety at Fort Lyon on the eastern plains, where their people would be given provisions and protection by the United States troops. 
Black Kettle, leading chief of around 163 mostly Southern Cheyenne, had led his band, joined by some Arapahos under Chief Niwot, to Fort Lyon in compliance with provisions of a peace parley held in Denver in September 1864.  After a while, the Native Americans were asked to relocate to Big Sandy Creek, less than 40 miles northwest of Fort Lyon, under the threat of their safety .  The Dog Soldiers, who had been responsible for many of the attacks and raids on whites, were not part of this encampment.
Most tribal warriors stood their ground, refusing to leave their home under the guise of a threat, leaving only about 75 men, plus all the women and children in the village. The men who remained were mostly too old or too young to hunt. Black Kettle flew a U.S. flag, with a white flag tied beneath it,  over his lodge, as the Fort Lyon commander had advised him. This was to show he was friendly and forestall any attack by the Colorado soldiers. 
Meanwhile, Chivington and 425 men of the 3rd Colorado Cavalry rode to Fort Lyon arriving on November 28, 1864. Once at the Fort, Chivington took command of 250 men of the 1st Colorado Cavalry and maybe as many as 12 men of the 1st Regiment New Mexico Volunteer Infantry then set out for Black Kettle's encampment. James Beckwourth, noted frontiersman, acted as guide for Chivington.  The following morning, Chivington gave the order to attack. Two officers, Captain Silas Soule and Lieutenant Joseph Cramer, commanding Company D and Company K of the First Colorado Cavalry, refused to obey and told their men to hold fire. 
However, the rest of Chivington's men immediately attacked the village. Ignoring the U.S. flag and a white flag that was run up shortly after the attack began, they murdered as many of the Indians as they could.
I saw the bodies of those lying there cut all to pieces, worse mutilated than any I ever saw before; the women cut all to pieces ... With knives; scalped; their brains knocked out; children two or three months old; all ages lying there, from sucking infants up to warriors ... By whom were they mutilated? By the United States troops ...— John S. Smith, Congressional Testimony of Mr. John S. Smith, 1865 
I saw one squaw lying on the bank, whose leg had been broken. A soldier came up to her with a drawn sabre. She raised her arm to protect herself; he struck, breaking her arm. She rolled over, and raised her other arm; he struck, breaking that, and then left her with out killing her. I saw one squaw cut open, with an unborn child lying by her side.— Robert Bent, New York Tribune, 1879 
There was one little child, probably three years old, just big enough to walk through the sand. The Indians had gone ahead, and this little child was behind, following after them. The little fellow was perfectly naked, travelling in the sand. I saw one man get off his horse at a distance of about seventy-five yards and draw up his rifle and fire. He missed the child. Another man came up and said, 'let me try the son of a b-. I can hit him.' He got down off his horse, kneeled down, and fired at the little child, but he missed him. A third man came up, and made a similar remark, and fired, and the little fellow dropped.— Major Anthony, New York Tribune, 1879 
Fingers and ears were cut off the bodies for the jewelry they carried. The body of White Antelope, lying solitarily in the creek bed, was a prime target. Besides scalping him the soldiers cut off his nose, ears, and testicles-the last for a tobacco pouch ...— Stan Hoig 
Jis' to think of that dog Chivington and his dirty hounds, up thar at Sand Creek. His men shot down squaws, and blew the brains out of little innocent children. You call sich soldiers Christians, do ye? And Indians savages? What der yer s'pose our Heavenly Father, who made both them and us, thinks of these things? I tell you what, I don't like a hostile red skin any more than you do. And when they are hostile, I've fought 'em, hard as any man. But I never yet drew a bead on a squaw or papoose, and I despise the man who would.
The natives, lacking artillery, could not make much resistance. Some of the natives cut horses from the camp's herd and fled up Sand Creek or to a nearby Cheyenne camp on the headwaters of the Smoky Hill River. Others, including trader George Bent, fled upstream and dug holes in the sand beneath the banks of the stream. They were pursued by the troops and fired on, but many survived.  Cheyenne warrior Morning Star said that most of the Indian dead were killed by cannon fire, especially those firing from the south bank of the river at the people retreating up the creek. 
In testimony before a Congressional committee investigating the massacre, Chivington claimed that as many as 500–600 Indian warriors were killed.  Historian Alan Brinkley wrote that 133 Indians were killed, 105 of whom were women and children.  White eye-witness John S. Smith reported that 70–80 Indians were killed, including 20–30 warriors,  which agrees with Brinkley's figure as to the number of men killed. George Bent, the son of the American William Bent and a Cheyenne mother, who was in the village when the attack came and was wounded by the soldiers, gave two different accounts of the natives' loss. On March 15, 1889, he wrote to Samuel F. Tappan that 137 people were killed: 28 men and 109 women and children.  However, on April 30, 1913, when he was very old, he wrote that "about 53 men" and "110 women and children" were killed and many people wounded. 
Although initial reports indicated 10 soldiers killed and 38 wounded, the final tally was 4 killed and 21 wounded in the 1st Colorado Cavalry and 20 killed or mortally wounded and 31 other wounded in the 3rd Colorado Cavalry; adding up to 24 killed and 52 wounded.  Dee Brown wrote that some of Chivington's men were drunk and that many of the soldiers' casualties were due to friendly fire  but neither of these claims is supported by Gregory F. Michno  or Stan Hoig  in their books devoted to the massacre.
Before Chivington and his men left the area, they plundered the teepees and took the horses. After the smoke cleared, Chivington's men came back and killed many of the wounded. They also scalped many of the dead, regardless of whether they were women, children or infants. Chivington and his men dressed their weapons, hats and gear with scalps and other body parts, including human fetuses and male and female genitalia.  They also publicly displayed these battle trophies in Denver's Apollo Theater and area saloons. Three Indians who remained in the village are known to have survived the massacre: George Bent's brother Charlie Bent, and two Cheyenne women who were later turned over to William Bent. 
The Sand Creek Massacre resulted in a heavy loss of life, mostly among Cheyenne and Arapaho women and children. Hardest hit by the massacre were the Wutapai, Black Kettle's band. Perhaps half of the Hevhaitaniu were lost, including the chiefs Yellow Wolf and Big Man. The Oivimana, led by War Bonnet, lost about half their number. There were heavy losses to the Hisiometanio (Ridge Men) under White Antelope. Chief One Eye was also killed, along with many of his band. The Suhtai clan and the Heviqxnipahis clan under chief Sand Hill experienced relatively few losses. The Dog Soldiers and the Masikota, who by that time had allied, were not present at Sand Creek.  Of about ten lodges of Arapaho under Chief Left Hand, representing about fifty or sixty people, only a handful escaped with their lives. 
After hiding all day above the camp, in holes dug beneath the bank of Sand Creek, the survivors there, many of whom were wounded, moved up the stream and spent the night on the prairie. Trips were made to the site of the camp but very few survivors were found there. After a cold night without shelter, the survivors set out toward the Cheyenne camp on the headwaters of the Smoky Hill River. They soon met up with other survivors who had escaped with part of the horse herd, some returning from the Smoky Hill camp where they had fled during the attack. They then proceeded to the camp, where they received assistance. 
The massacre disrupted the traditional Cheyenne power structure, because of the deaths of eight members of the Council of Forty-Four. White Antelope, One Eye, Yellow Wolf, Big Man, Bear Man, War Bonnet, Spotted Crow, and Bear Robe were all killed, as were the headmen of some of the Cheyenne military societies.  Among the chiefs killed were most of those who had advocated peace with white settlers and the U.S. government.  The net effect of the murders and ensuing weakening of the peace faction exacerbated the developing social and political rift. Traditional council chiefs, mature men who sought consensus and looked to the future of their people, and their followers, were opposed by the younger and more militaristic Dog Soldiers.
Beginning in the 1830s, the Dog Soldiers had evolved from a Cheyenne military society of that name into a separate band of Cheyenne and Lakota warriors. They took as their territory the area around the headwaters of the Republican and Smoky Hill rivers in southern Nebraska, northern Kansas, and the northeastern Colorado Territory. By the 1860s, as conflict between Indians and encroaching whites intensified, the Dog Soldiers and military societies within other Cheyenne bands countered the influence of the traditional Council of Forty-Four chiefs who, as more mature men, took a larger view and were more likely to favor peace with the whites.  To the Dog Soldiers, the Sand Creek massacre illustrated the folly of the peace chiefs' policy of accommodating the whites through treaties such as the first Treaty of Fort Laramie and the Treaty of Fort Wise.  They believed their militant position toward the whites was justified by the massacre. 
The events at Sand Creek dealt a fatal blow to the traditional Cheyenne clan system and the authority of its Council of Chiefs. It had already been weakened by the numerous deaths due to the 1849 cholera epidemic, which killed perhaps half the Southern Cheyenne population, especially the Masikota and Oktoguna bands.  It was further weakened by the emergence of the separate Dog Soldiers band. 
After the brutal slaughter of those who supported peace, many of the Cheyenne, including the great warrior Roman Nose, and many Arapaho joined the Dog Soldiers. They sought revenge on settlers throughout the Platte valley, including an 1865 attack on what became Fort Caspar, Wyoming.
Following the massacre, the survivors reached the camps of the Cheyenne on the Smokey Hill and Republican rivers. The war pipe was smoked and passed from camp to camp among the Sioux, Cheyenne and Arapaho warriors in the area. In January 1865, they planned and carried out an attack with 1,000 warriors on the stage station and fort, then called Camp Rankin, at present-day Julesburg, Colorado. This was followed by numerous raids along the South Platte both east and west of Julesburg, and a second raid on the town of Julesburg in early February. The associated bands captured much loot and killed many white settlers, including men, women and children. The bulk of the Indians then moved north into Nebraska on their way to the Black Hills and the Powder River Country. 
Black Kettle continued to speak for peace and did not join in the second raid or in the journey to the Powder River country. He left the camp and returned with 80 lodges to the Arkansas River to seek peace with the Coloradoans. 
Initially, the Sand Creek engagement was reported as a victory against a brave and numerous foe. Within weeks, however, witnesses and survivors began telling stories of a possible massacre. Several investigations were conducted – two by the military, and one by the Joint Committee on the Conduct of the War. The panel declared: 
As to Colonel Chivington, your committee can hardly find fitting terms to describe his conduct. Wearing the uniform of the United States, which should be the emblem of justice and humanity; holding the important position of commander of a military district, and therefore having the honor of the government to that extent in his keeping, he deliberately planned and executed a foul and dastardly massacre which would have disgraced the veriest savage among those who were the victims of his cruelty. Having full knowledge of their friendly character, having himself been instrumental to some extent in placing them in their position of fancied security, he took advantage of their in-apprehension and defenceless condition to gratify the worst passions that ever cursed the heart of man.
Whatever influence this may have had upon Colonel Chivington, the truth is that he surprised and murdered, in cold blood, the unsuspecting men, women, and children on Sand creek, who had every reason to believe they were under the protection of the United States authorities, and then returned to Denver and boasted of the brave deed he and the men under his command had performed.
In conclusion, your committee are of the opinion that for the purpose of vindicating the cause of justice and upholding the honor of the nation, prompt and energetic measures should be at once taken to remove from office those who have thus disgraced the government by whom they are employed, and to punish, as their crimes deserve, those who have been guilty of these brutal and cowardly acts.
Statements taken by Major Edward W. Wynkoop and his adjutant substantiated the later accounts of survivors. These statements were filed with his reports and can be found in the Official Records of the War of the Rebellion, copies of which were submitted as evidence in the Joint Committee of the Conduct of the War and in separate hearings conducted by the military in Denver. Lieutenant James D. Cannon describes the mutilation of human genitalia by the soldiers, "men, women, and children's privates cut out. I heard one man say that he had cut a woman's private parts out and had them for exhibition on a stick. I heard of one instance of a child, a few months old, being thrown into the feed-box of a wagon, and after being carried some distance, left on the ground to perish; I also heard of numerous instances in which men had cut out the private parts of females and stretched them over their saddle-bows, and some of them over their hats." 
During these investigations, numerous witnesses came forward with damning testimony, almost all of which was corroborated by other witnesses. One witness, Captain Silas Soule, who had ordered the men under his command not to fire their weapons, was murdered in Denver just weeks after offering his testimony. However, despite the Joint Committee on the Conduct of the Wars' recommendation, no charges were brought against those who committed the massacre. Chivington was beyond the reach of army justice because he'd already resigned his commission. The closest thing to a punishment he suffered was the effective end of his political aspirations.
In his autobiographical Memories of a Lifetime in the Pike's Peak Region, Irving Howbert, an 18-year-old cavalryman who was later one of the founders of Colorado Springs, defended Chivington, having claimed instead that the Indian women and children were not attacked, though a few who did not leave the camp were killed once the fighting began. He insisted that the number of warriors in the village was equal to the force of the Colorado cavalry. Chivington, claimed Howbert, was retaliating for Indian attacks on wagon trains and settlements in Colorado and for the torture and the killings of citizens during the preceding three years. Howbert said the evidence of the previous Indian attacks on the settlers was shown by their confiscation of "more than a dozen scalps of white people, some of them from the heads of women and children."  Howbert claimed that the account of the battle to the United States Congress made by Lieutenant Col. Samuel F. Tappan was inaccurate, accusing Tappan of giving a false view of the battle because Tappan and Chivington had been military rivals. 
A monument installed on the Colorado State Capitol grounds in 1909 lists Sand Creek as one of the "battles and engagements" fought by Colorado troops in the American Civil War. In 2002, the Colorado Historical Society (now History Colorado), authorized by the Colorado General Assembly, added an additional plaque to the monument, which states that the original designers of the monument "mischaracterized" Sand Creek by calling it a battle. 
After the actual details of the massacre became widely known, the United States federal government sent a blue ribbon commission whose members were respected by the Indians, and the Treaty of the Little Arkansas  was signed in 1865. It promised the Indians free access to the lands south of the Arkansas River, excluded them from the Arkansas River north to the Platte River, and promised land and cash reparations to the surviving descendants of Sand Creek victims.
However, the treaty was abrogated by Washington less than two years later, all major provisions ignored, and instead the Medicine Lodge Treaty reduced the reservation lands by 90%, located in much less desirable sites in Oklahoma. Later government actions further reduced the size of the reservations.
The site, on Big Sandy Creek in Kiowa County, is now preserved by the National Park Service. The Sand Creek Massacre National Historic Site was dedicated on April 28, 2007, almost 142 years after the massacre. The American Battlefield Trust and its partners have preserved 640 acres of Sand Creek and deeded it to the national historic site. 
The Sand Creek Massacre Trail in Wyoming follows the paths of the Northern Arapaho and Cheyenne in the years after the massacre.  It traces them to their supposed wintering on the Wind River Indian Reservation near Riverton in central Wyoming, where the Arapaho remain today. The trail passes through Cheyenne, Laramie, Casper, and Riverton en route to Ethete in Fremont County on the reservation. In recent years, Arapaho youth have taken to running the length of the trail as endurance tests. Alexa Roberts, superintendent of the Sand Creek Massacre National Historic Site, has said that the trail represents a living portion of the history of the two tribes.
An exhibit about Sand Creek, titled Collision: The Sand Creek Massacre 1860s-Today, opened in 2012 with the new History Colorado Center in Denver. The exhibit immediately drew criticism from members of the Northern Cheyenne tribe. In April 2013, History Colorado agreed to close the exhibit to public view while consultations were made with the Northern Cheyenne. 
On December 3, 2014, Colorado Governor John Hickenlooper formally apologized to descendants of Sand Creek massacre victims gathered in Denver to commemorate the 150th anniversary of the event. Hickenlooper stated, "We should not be afraid to criticize and condemn that which is inexcusable. ... On behalf of the State of Colorado, I want to apologize. We will not run from this history."  
In 2015, construction of a memorial to the Sand Creek Massacre victims began on the Colorado Capitol grounds. 
The Sand Creek massacre has been depicted or referenced in multiple works, spanning a variety of media.
The massacre has been portrayed in several western movies, including Tomahawk (1951); Massacre at Sand Creek ( Playhouse 90) (1956); The Guns of Fort Petticoat (1957); Soldier Blue (1970); The Last Warrior (1970); Young Guns (1988); Last of the Dogmen (1995); and The Last Samurai (2003). The massacre is referenced by Trevor Slattery in Iron Man 3 (2013). 
The event has also been written about in such works of literature as The Massacre at Sand Creek (1995) by Bruce Cutler; A Very Small Remnant (1963) by Michael Straight;" Young Sherlock Holmes: Fire Storm" by Andrew Lane, 2011 Centennial (1974) by James Michener; From Sand Creek (1981) by Simon Ortiz; Bury My Heart at Wounded Knee (1971) by Dee Brown and Choke Creek (2009) by Lauren Small. Flight (2007) by Sherman Alexie depicts a fictionalized version of the event.
- Peter La Farge's song "The Crimson Parson" is about the massacre at Sand Creek.
