The Bozeman Trail  

Westward expansion in the United States emerged at the beginning of the 19th century with the Louisiana Purchase, accelerating after the doctrine of Manifest Destiny emerged, leading to the California Gold Rush and other large-scale emigration movements. The Western frontier provided those seeking fortune the opportunity to achieve the American Dream. This rapid influx in new Western residents led to a collision with Native American sovereignty, as land that had been utilized by Indigenous communities for generations quickly became disputed. Treaties such as the 1851 Treaty of Fort Laramie attempted to define tribal land and maintain friendly relations but were quickly undermined by the settlement, military expansion, and increasing demand for Western resources of tribal regions. Tensions would escalate on the Northern Plains as wagon routes utilizing Native hunting grounds became the epicenter for Native armed resistance.  

During the winter of 1862, a Georgian entrepreneur named John Merian Bozeman discovered a shortcut to the Montana gold fields that would transform regional transportation in the Rocky Mountains, affecting its Indigenous inhabitants forever. Bozeman left his family in Pickens County, Georgia in search of wealth and adventure. Traveling to Colorado in the Pikes Peak Gold Rush that lasted throughout the early 1860s, Bozeman ultimately failed to strike it rich before looking for other opportunities.

Bozeman’s Native American corridor cut 500 miles and a month of travel time from existing travel routes to the Montana gold fields, creating an economic incentive for emigrants despite the risk. Although still expensive, alternatives to Bozeman’s route were expensive and long, as stagecoaches ran from Salt Lake City to Virginia City, steamboats up the Missouri River to Fort Benton followed by a stagecoach south to Helena and Virginia City, or the Mullan Road from the northwest (Fort Walla Walla to Fort Benton). The wagon was the cheapest and most popular option for most Americans in search of wealth, as a fully supplied wagon cost around $600-800 dollars. Stagecoach travel from Salt Lake City to Virginia City often cost several hundred per rider, often exceeding the cost of a fully supplied wagon. Steamboat passage up the Missouri was also quite costly, involving high freight costs and fares along with the unpredictable conditions of river travel. In the context of a Gold Rush, the most important factor was not just affordability but timeliness. Those who arrived early had access to the most productive claims, creating an opportunity cost for long travel periods. By 1865, Montana had amassed roughly twenty-thousand emigrants which contributed to the influx of firearms on the Western Plains, directly escalating an already tense region. His route became infamous not for its safety or convenience, but for its extreme efficiency as a direct shortcut.  

Bozeman would only guide two separate wagon trains to Montana. The first trip left in 1863, but most of his train returned to the Oregon Trail after being warned of hostility if they continued by Cheyenne and Lakota warriors. However, Bozeman and Jacobs, along with a substantially reduced party size of ten men on horseback utilizing pack animals, saw the potential exploitation of this prized Native route and were determined to continue to Virginia City. Bozeman’s party chose to travel under the cover of darkness, and along the way would lose their pack animals carrying nearly all their food rations, leaving the group starving. After four days without food, John Bozeman managed to shoot a Bald Eagle near the headwaters of the Clark’s Fork River, providing enough sustenance to keep his party alive and permitting their safe arrival to Bannack, opening the Bozeman Trail in 1863.  

In the Spring of 1864, Bozeman’s second trip with a much larger guided wagon train proved much more difficult than the first. One of the greatest disadvantages to Bozeman’s route in comparison to the Oregon Trail was the lack of established supply posts, resulting in long stretches without water and food in the arid Powder River Basin. This second successful yet tedious expedition reached Virginia City and Bannack later in 1864 before Bozeman returned to the Gallatin Valley, establishing the town of Bozeman as a testament to his rise in the region. Bozeman became a supply stop along the trail to the gold fields and John would obtain election as recorder of the district and eventually probate judge in Gallatin County.  

Another prominent mountain man and guide who established a competing route to Bozeman's was the notorious Jim Bridger. Bridger had been working as a trapper and trader across the Rocky Mountains for 30 years (1820-1850) where he co-founded trading posts such as Fort Bridger. By the late 1850s, the fur trade had declined, and Bridger began guiding wagon trains during the peak of American expansion. His route ran west of the Bighorn Mountains through the Bighorn Basin, deliberately avoiding the Powder River Basin where tribes actively resisted emigrant traffic. Bridger’s route, although significantly safer, was 150 miles longer and provided worse grazing and water supplies for wagon trains. In comparison, the Bozeman Trail ran east of the Bighorn Mountains offering a direct shortcut to the Montana gold fields. In the Spring of 1864, Bozeman and Bridger both raced guided wagon trains to Bannack to prove the advantage of their respective routes, with Bozeman drawing on Bridger’s prior knowledge of Yellowstone River crossings during his years as a trapper, to locate a viable crossing for wagons. Bozeman’s wagon train was significantly larger than Bridger’s, amassing over 150 wagons in his party yet nonetheless arriving to Bannack in late June 1864 before Bridger’s party, establishing the validity of the Bozeman Trail for other guides and the military alike.  

By the end of 1864, thousands had arrived at the goldfields via the Bridger and Bozeman Trails without incident, resulting in the establishment of the town of Bozeman as a supply post and mining town named after the guide who helped bring settlers to the region. As a failed prospector himself, Bozeman strongly encouraged the emigrants in his wagon trains to settle the Gallatin Valley instead of continuing to the gold fields, promoting its fertile soil and potential for farming. 

Between 1864-1865, approximately 2,000 people utilized the Bozeman Trail resulting in an outcry for federal military protection. This resulted in the construction of three forts along the trail named after recently victorious Civil War generals, Fort Reno and Fort Phil Kearney in Wyoming, and Fort C.F. Smith in Southern Montana in 1866. Fort Ellis would also be built in 1867 to protect the Bozeman Pass between the cities of Bozeman and Virginia City before being decommissioned in 1886. These forts were built to guard and protect travelers along the trail, however quickly depleted necessary Native game and intensified violence within the region of present-day Montana and Wyoming. These Forts would later fall under constant siege by Red Cloud and his warriors, resulting in retaliatory raids and massacres that plagued the war on the Plains.   

In the Spring of 1867, Gallatin Valley was in a constant state of paranoia over the threat of Indigenous raids, leading to the still controversial narrative regarding John Bozeman’s untimely death. One version has it that John Bozeman and a colleague Thomas Cover had spent the night at a prominent Bozeman millionaires ranch, Nelson Story Sr., before planning to obtain a government flour contract for mill owner Thomas Cover at Fort C.F. Smith. It is rumored that Bozeman outwardly expressed concern over the trip, with one witness even suggesting that Bozeman, uneasy about the trip, asked him to take his place on the trip. Along the way, they stopped for lunch near the Yellowstone River and soon were in the sights of what Bozeman believed to be five friendly Crow men. Bozeman falsely identified these Piegan Blackfeet as Crow natives and soon fell under gunfire. Bozeman was shot twice through the chest and killed instantly while it is reported Thomas Cover was shot once through the shoulder from behind while attempting to flee. Cover claimed that the Blackfeet then stole their horses, forcing him to walk back to the ranch where he would not arrive until twelve hours later.  

Subsequent letters to acting Montana Governor Thomas F. Meagher resulted in the construction of Fort Ellis on the eastern edge of the Gallatin Valley in August of 1867. Nelson Story Sr. sent his best trackers to investigate the crime scene, and they reported no discoveries of Native American activity. This revelation coupled with an analysis of Cover’s injuries reflecting powder burns on the front of his torso contradicted the claim that he was shot from a distance and from behind, and rumors began circulating that suggested Bozeman was intentionally killed by his companion, Thomas Cover. Cover’s hypothesized motives include a dispute over a romantic interest, yet no documentation refers to this other than oral retellings, and he would never be charged or face trial for the murder of thirty-two-year-old John Bozeman. The accusation that Bozeman was murdered by Piegan Blackfeet was entirely possible, however is more reflective of the overwhelming propaganda of the era depicting Native Americans as violent individuals targeting white settlers.   

The controversy surrounding the death of John Bozeman was reflective of the extreme tension on the Northern Plains in 1867. The event intensified settlers fear of Indigenous violence and reinforced calls for military protection along the Bozeman Trail, accelerating the hostility of the Powder River Basin. The uncertainty of his murder allowed false narratives of Indigenous violence to spread despite the existence of conflicting evidence.  

Red Cloud was the notorious leader of the Oglala Lakota known for his courage, firm diplomacy, and unprecedented strategy and tactics. Born in Nebraska in 1822, he led his people to several important victories over United States military forces. He was credited with 80 coups, or individual feats of bravery, and was chosen as tribal leader over the Ogalala hereditary claimant. The Oglala Lakota were the largest division of the Lakota Nation, and Red Cloud became the most successful war leader among the Lakota and Cheyenne, believing it his mission to protect the Lakota’s last hunting grounds and forcing the United States to meet his demands in the 1868 Treaty of Fort Laramie. Paha Sapa, or the Black Hills, are the extremely sacred ancestral lands of the Lakota tribe, serving as the tribe’s spiritual center and often the setting for the young to partake in a vision quest. By the early 1860s, American prospectors and settlers encroached on Lakota territory in Minnesota and Wisconsin; the Lakota were forced to move west with the remaining bison herds. This forced them into lands inhabited by the Crow, Shoshone, Arikara, Mandan, Gros Ventre, Blackfeet, and Assiniboine, resulting in cycles of intertribal mourning wars. Mourning wars were vengeance raids practiced by most Native American tribes to replace and grieve family members lost to war or death. It was no coincidence that the Native guides for many military generals and captains, including the infamous General Custer, were from these tribes, as the Lakota became the dominant force in the region.  

Outright assaults on wagon trains by Native American forces were extremely rare, however there were exceptions such as the Townsend Wagon Train Fight. On July 7th, 1864, 150 wagons utilizing the Bozeman Trail were attacked on the Powder River in present day Wyoming. A six-hour battle ensued where emigrants managed to repel Lakota and Northern Cheyenne warriors due to their superior weaponry and scale of the party. The party of emigrants in search of Montana gold led by Captain Absalom Townsend only lost four men, yet this conflict still resulted in a dramatic increase of military presence along the Bozeman trail. The wagon train continued their journey the next day and reached Virginia City a month and a half later safely. 

In the spring of 1866, the United States government sought to reopen the afflicted Bozeman Trail full of  Red Cloud’s forces defending their hunting grounds, inviting Lakota, Cheyenne, and Arapaho tribes to a peace conference at Fort Laramie. The trail could only be successfully operated with the cooperation of Red Cloud and his forces to prevent further hostility. Nearly 2,000 Natives showed up, including Red Cloud and a young Crazy Horse, to hear the United States proposal. Red Cloud abruptly left the conference when he discovered the United States intended to bring in more troops and expand their forts, vowing to assert a defensive against the incursion. To defend against an increasing number of Native attacks, the military began traveling with emigrant wagon trains, with one week reporting 24 civilian deaths. As the travel season of 1866 ended, Red Cloud’s coalition increased strikes around forts as woodcutting parties and cowboys grazing their cattle faced almost daily assaults. Red Cloud employed hit and run tactics throughout the fall attacking the supply line of forts, preventing the military from leaving their headquarters for longer than a few days.  

One of Red Cloud’s most notorious victories was the victory over an arrogant Captain William Fetterman in December of 1866. Called the Battle of the Hundred in the Hands by Plains Natives due to the severe force disparity, Fetterman was regarded as extremely reckless and famously said, “With 80 men, I could ride through the entire Sioux Nation”. Near Fort Phil Kearney, a young and ambitious Crazy Horse waited with Red Cloud’s forces to draw Fetterman’s columns over a ridge he had been instructed not to cross, falling into the range of thousands of waiting Lakota warriors. Fetterman was a prospect for commanding a new fort and was a high-ranking officer in the Civil War. In this well staged trap, Fetterman was dispatched to protect a woodcutting party, eventually being lured over Lodge Trail Ridge ignoring direct orders, and would soon enter the crosshairs of 1500 waiting Lakota, Cheyenne, and Arapaho. The Battle of the Hundred in the Hands was a complete victory and regarded as the most successful military feats of the Plains Indians. Notorious Ogalala Lakota Warrior American Horse was present and is often credited with the killing of Captain Fetterman.  

Lakota raids became so frequent, greatly outnumbered federal troops became confined to their forts and work outfits only, resulting in the Hayfield and Wagon Box fights of 1867. In these last major engagements of Red Cloud’s war, less than fifty-armed men defended themselves against waves of Red Cloud’s warriors with little casualty, discouraging Red Cloud’s coalition. These humiliating defeats of United States forces officially closed the Bozeman trail by making emigrant travel impossible, resulting in an  all out war between United States Forts and indigenous tribes. Throughout the entirety of 1867, not a single wagon moved along the Bozeman trail to the Montana goldfields virtually closing it due to Indigenous resistance.  

The 1868 Treaty of Fort Laramie was negotiated after Red Cloud’s War between the Lakota Nation and United States government as a peace treaty in response to Red Cloud’s dominance in the region, recognizing the sacred South Dakota Black Hills as part of the Great Sioux Reservation set aside for exclusive use by the Lakota people as long as all tribal war parties ceased. The treaty established the Great Sioux Reservation for the, “...absolute and undisturbed use and occupation” of the Lakota and prevented non-Native settlement without tribal consent. Red Cloud refused to sign the treaty until all forts along the trail were no longer occupied, instructing his warriors to burn them down immediately. The Treaty of Fort Laramie created “unceded Indian territory” in present day Eastern Montana and Wyoming, with the stipulations only permitting their use for hunting grounds if the near extinct Bison still roamed, or if the “game justified the chase.” These unceded hunting grounds were not recognized as sovereign territory, but rather as conditional hunting grounds. The 1868 Treaty of Fort Laramie marked a shift in sovereignty as the Lakota people’s autonomy became connected to treaty conditions enforced by the United States government.  Although serving as a successful Native military resistance against the United States military, Red Cloud’s willingness to accept reservation policy in return for the Black Hills raised questions on if the treaty stipulations were ever properly conveyed, resulting in his lobbying in Washington D.C. 

“In 1868 Men came out and brought papers. We could not read them, and they did not tell us truly what was in these papers. We thought the treaty was to remove the forts, and that we should cease fighting. They said we had bound ourselves to trade on the Missouri, and we said no, we did not want that. The interpreters deceived us. When I went to Washington I saw the Great Father. The Great Father showed me what the treaties were; he showed me all these points and showed me that interpreters had deceived me and did not let me know what the treaty truly stated. All I want is right and justice. I have tried to get from the Great Father what is right and just. I have not altogether succeeded.” (Excerpt from Red Cloud’s Speech at Cooper Union 1860)  

 Red Cloud along with other Lakota leaders would go on to visit Washington D.C. and meet with the President to discuss indigenous constituency, yet the Black Hills would soon be violently taken. In 1876, Red Cloud advised the Lakota toward peace while Crazy Horse and Sitting Bull attempted to defend their sovereignty with armed resistance. This led to the fracturing of the Lakota Tribe, with many older Natives like Red Cloud and Spotted Tail, Crazy Horse’s uncle, accepting the confinement of reservations and refusing compensation for their stolen lands such as the sacred Paha Sapa (Black Hills). To this day, the Lakota have refused to accept any amount of financial compensation for the Black Hills reflecting their moral stance that the Black Hills were illegally seized and were never for sale. Red Cloud would eventually be removed as an Ogalala Lakota leader by the United States following a dispute with Indian Agent V.T. McGillicuddy. Red Cloud died in 1909 on the Pine Ridge Reservation in South Dakota, home of the Ogalala Lakota after the 1868 Treaty of Fort Laramie and originally part of the Great Sioux Reservation. 

1868 marked the official closing of the Bozeman trail due to Indigenous resistance and paved the way for the future of transportation: the railroad. The Bozeman Trail would be the last of the great Gold Rush routes West, expanding a region facing enormous pressure leading to its ultimate replacement by contemporary transportation methods. Large portions of the historic Bozeman Trail are still utilized today, as its foundation was utilized by the Northern Pacific Railroad, chartered in 1864, beginning construction in 1870, and with the tracks reaching the town of Bozeman in 1883. The railroad and expansion of both military and settlement establishments turned the city of Bozeman into a regional economic center, enabling large quantities of Gallatin County crops and livestock to be cultivated and transported out coupled with the influx of incoming tourism to Yellowstone National Park in 1872. Several sections of the railroad utilized specific passages of the Bozeman Trail, including the Yellowstone River corridor from the emerging railroad town of Billings to Livingston. It also utilized a portion of Bozeman Pass, requiring the blasting of tunnels from Livingston to Bozeman and following the same corridor used by Bozeman’s emigrants. After descending the pass, the railroad follows the route further west through the Gallatin Valley towards Three Forks.  

Not only did the Bozeman Trail lay the foundation for the railroad, it also was utilized in the late 20th century for the Interstate Highway System, proving the efficacy of Bozeman’s Trail across centuries. During the 1960s and 70s, major sections of Interstate 90 were constructed across Montana with many portions following the ruts of the Bozeman Trail. The section emigrants used to enter Montana, the Bighorn corridor, skirting the Bighorn Mountains in present day Sheridan, Wyoming, now is a portion of Interstate 90. Running parallel to the railroad, Interstate 90 also utilizes the Yellowstone Valley corridor from Billings to Livingston and the Gallatin Valley corridor from Bozeman to Three Forks.  

Bozeman did not create this route but rather adapted long standing Native travel corridors to supplement American westward expansion. The continued use of these corridors by both the Northern Pacific Railroad and Interstate 90 demonstrate that the Bozeman Trail was not simply a short-lived gold rush route, but a generational transportation corridor whose efficacy shaped regional infrastructure in Montana and surrounding Rocky Mountain regions.
