It was cold. That’s the first thing you have to realize about November 29, 1864. The sun hadn't even cleared the horizon over the Big Sandy Creek in the Colorado Territory when the sound of hooves started thumping against the frozen earth. Most of the people in the camp—largely Southern Cheyenne and Arapaho—were still asleep. They thought they were safe. They had been told they were under the protection of the U.S. Army.
Then the screaming started.
What happened at the Sand Creek Massacre wasn't a battle. It wasn't a "clash of cultures" or a misunderstanding in the heat of war. Honestly, it was a planned execution of non-combatants. When you look at the primary sources, the letters from soldiers who refused to fire, and the testimony given to Congress afterward, the picture isn't just dark—it's nauseating.
The Setup: Peace Treaties and Broken Promises
By 1864, the Colorado Gold Rush had turned the region into a powder keg. White settlers were pouring in, and the buffalo herds were thinning out. The Cheyenne and Arapaho were squeezed. Chief Black Kettle, a man who desperately wanted peace, had already seen what happened when his people fought the U.S. government. He didn't want that for his tribe.
He did everything right.
Black Kettle and other leaders met with Governor John Evans and Colonel John Chivington in Denver earlier that fall. They were told that if they moved their bands to specific areas and reported to military forts, they’d be considered "friendly." Basically, they were checking in so they wouldn't get caught in the crossfire of the broader Indian Wars. They set up camp at Sand Creek because they were told to be there by the commander at Fort Lyon, Major Edward Wynkoop.
Black Kettle even flew a large American flag over his tipi. Underneath it, he tied a white flag of truce. He wanted there to be zero doubt about who they were.
Enter John Chivington
You can't talk about this without talking about Chivington. He was a Methodist preacher turned Colonel. A big man. Ambitious. He was looking for a political career, and in 1864 Colorado, "killing Indians" was a great way to get votes. He didn't care about treaties. He famously told his men, "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."
He led about 675 men—the 3rd Colorado Cavalry and elements of the 1st—straight toward that peaceful camp. These weren't seasoned frontier veterans for the most part; many were "100-day volunteers" whose enlistments were about to run out. They wanted a fight before they went home.

The Morning of the Massacre
When the troops arrived, some of the soldiers were hesitant. Captain Silas Soule and Lieutenant Joseph Cramer saw the white flag. They knew this camp was peaceful. Soule actually ordered his men not to fire.
But Chivington gave the order.
The initial volley hit the camp like a physical wall. People scrambled out of their lodges, confused and terrified. Black Kettle stood by his flagpole, waving his arms, shouting to his people that they were safe, that the flag would protect them. He was wrong. The soldiers opened up with mountain howitzers. Shrapnel tore through the buffalo-hide tipis.
A Brutality That Defies Description
This is where the history gets really heavy. Most of the men were away hunting. The camp was full of women, children, and the elderly. White Antelope, an older chief, ran toward the soldiers with his hands up, singing his death song: "Nothing lives long, except the earth and the mountains." He was shot dead where he stood.
The survivors fled into the sandy bed of the creek. They tried to dig trenches into the banks with their bare hands to hide the children. It didn't matter. The cavalry followed them.
The eyewitness accounts from the subsequent Congressional investigations are chilling. Soldiers didn't just kill; they mutilated. They took trophies. We aren't just talking about scalps. They took body parts to decorate their hats and saddles. They killed infants. They cut open pregnant women.
Stan Hoig, a leading historian on this event, documented that roughly 150 to 200 Native Americans were murdered. About two-thirds of them were women and children.
The Cover-Up and the Whistleblowers
Initially, Chivington was hailed as a hero in Denver. The local newspapers ran headlines about a "Great Victory." They displayed the "trophies" in local theaters. But the lie couldn't hold.

Silas Soule and Joseph Cramer wrote letters to their superiors. They described the "indiscriminate slaughter" and the "fiendish" behavior of the troops. Because of their bravery—Soule was actually assassinated in Denver shortly after testifying—the federal government was forced to look into it.
Three Separate Investigations
The U.S. government ended up conducting three different inquiries into what happened at the Sand Creek Massacre:
- A military commission.
- The Joint Committee on the Conduct of the War.
- The Senate Bureau of Indian Affairs.
The Joint Committee on the Conduct of the War was blunt. They concluded that Chivington "deliberately planned and executed a foul and dastardly massacre." They noted that he took advantage of the "unsuspecting condition" of the Indians.
Despite these findings, no one was ever legally punished. Chivington had already resigned from the military, making him ineligible for a court-martial. He never faced a day in jail. He just lost his political prospects.
Why This Matters Today
You might wonder why we’re still talking about something that happened in a dry creek bed 160 years ago. Honestly, it’s because the scars never really healed. For the Cheyenne and Arapaho people, Sand Creek isn't "ancient history." It’s a family trauma.
The massacre fundamentally changed the Plains Wars. Before Sand Creek, many tribes were divided on whether to trust the U.S. government. After Sand Creek, the word spread: "The whites cannot be trusted, even when they promise peace." This led to a massive escalation in violence across the West, including the Battle of the Little Bighorn years later.
It also changed how the U.S. military viewed its own ethics. The testimony of Silas Soule remains a core case study in military ethics—specifically, the duty to refuse an unlawful order.
Correcting the Myths
There are a few things people still get wrong about this event.

First, it wasn't a "battle." You still see that term in some older textbooks. A battle implies two opposing armed forces. This was an attack on a village of dependents.
Second, the numbers. Chivington claimed he killed 500 or 600 "warriors." This was a total fabrication to make his "victory" look more impressive. The actual count was much lower, and the "warriors" were mostly old men trying to shield their grandkids.
Third, the location. For a long time, people weren't even sure exactly where it happened because the creek bed shifts over time. It wasn't until the late 1990s and early 2000s that a combination of archaeological work and tribal oral tradition pinpointed the site. In 2007, it became the Sand Creek Massacre National Historic Site.
What You Should Do Now
History isn't just about memorizing dates; it's about understanding the ripple effects. If you want to actually grasp the weight of this event, don't just take my word for it.
Read the Soule and Cramer letters. You can find them in the National Archives. Seeing the raw, unfiltered disgust from soldiers who were actually there changes how you view the "Old West."
Visit the National Historic Site. If you're ever in Eads, Colorado, go there. It's an intensely quiet, heavy place. The Park Service does a great job of letting the land tell the story without over-sensationalizing it.
Support Tribal Education. The Northern Cheyenne in Montana and the Cheyenne and Arapaho Tribes in Oklahoma still carry the cultural weight of this. Look into the Sand Creek Massacre Spiritual Healing Run, an annual event where tribal members run from the site to Denver to honor the victims.
Check your sources. When reading about Western history, look for accounts that include tribal oral histories. For over a century, the only "official" record was the one written by the people who committed the act. The real story only comes out when you listen to the survivors' descendants.
The Sand Creek Massacre stands as a stark reminder of what happens when ambition and prejudice override humanity. It’s a difficult chapter to read, but it’s one that defines the American West as much as any gold rush or railroad. Understanding the truth of that morning is the only way to move toward any kind of real reconciliation.
