Note: This is the eighth of a series of lists of the U. S. forts of the Wild West. It is intended for use in research by writers, readers, movie fans, and others, so not much information is provided in this list itself; instead, it refers readers, by way of embedded links, to websites that provide brief historical accounts of the forts and, in many cases, one or more photographs or illustrations associated with each of the forts. All photographs and illustrations are in the public domain.
Montana was admitted to the Union on November 8, 1889; before then, it was Montana Territory
Fort Benton
Like a number of other 19th-century U. S. Western frontier posts, Fort Benton, established in 1848, in Montana Territory, on the Missouri River, made the cut: it is recognized as a National Historic Landmark.
Initially an American Fur Trading post, it brought traders on steamboats from the east as well as fur traders, "gold seekers" and settlers, the latter two groups of whom were, respectively, on their way to hoped-for fortunes or land of their own. Freight, too, was shipped by wagon along oxen trails, headed for "isolated settlements" to the west ("Fort Benton National Historic Landmark," National Park Service).
A National Park Service (NPS) map on the NPS's Fort Benton National Historic Landmark locates numerous sites along the Lewis and Clark National Historic Trail, which extends from Pittsburg, Pennsylvania, to the Pacific Ocean. As might be expected, many of these points of interest are the sites of 19th-centtury (and earlier) U. S. Western frontier forts. "Traveling" this map is a great way to explore this period of the nation's history: the points of interest include links to websites that provide accounts of the locations' storied histories.
One of the more colorful characters associated with Fort Benton is card dealer and gambler Eleanor Dumont (aka "Madame Mustache") (1834-1879) and Shep, "who famously waited for his deceased owner at the Fort Benton rail depot" ("Fort Benton," Wikipedia).
Fort Missoula
During World War I, it was "a technical training center," it served a the ignoble role of serving as "the nation’s largest civilian detention camp, interning German and Italian nationals." Then, until its closure in 1948, Fort Missoula became "a a medium-security military prison" ("Fort Missoula," Montana History Portal).
Fort Peck
The Discovering Montana website's "Fort Peck, Montana" gives a thumbnail account of the Valley County fort for which the small, once-government-owned neighboring city took its name:
Fort Peck, Montana, was established as a trading post by Colonel Campbell K. Peck and his partner, Commander E.H. Durfee, in 1867. The town monopolized the fur trade with the Assiniboine and Sioux . . . . . Fort Peck later became an Indian agency in 1873.
The Wikipedia article "Fort Peck, Montana," provides a bit more information, citing Abe Farwell, an employee of "the Leavenworth, Kansas[,] trading firm of Durfee and Peck as having "constructed the Fort Peck trading post along the Missouri River" and pointing out that, in 1888, the Montana Territory Indian agency that had operated at the fort from 1873 "was moved," in 1878, "to its current location" in Poplar, Montana.
Fort Logan (Camp Baker)
Troops encamped at Fort Logan, Colorado, 1917 or 1918
Camp Bakker was established in 1869, in Montana Territory, as a protection against Native American raids. Eight years later, it was renamed Fort Logan; in 1880, it was abandoned. Today, only its blockhouse (fortified building) remains standing ("Fort Logan," The Historical Marker Database).
Fort Logan, 1098.
The fort also had the mission of protecting the freight road running between the fort and Helena and "provided troops for many of the campaigns in western Montana, including the Nez Perce War in 1877" ("Fort Logan, Montana," Legends of America).
Fort Lewis
During the 1830s, Fort Lewis was established in Montana Territory as a fur trading post on the Yellow River, as "part of [a] broader network of trading posts [and] would . . . have been a hub of activity and commerce [until] . . . . the fur trade waned ("10 Historic Forts in Montana" (Historic Forts).
Trading posts in Montana
Fort Custer
Built in 1877, "on an extensive elevated plateau in the fork of two streams," Fort Custer was an active military post until 1898.
Constructed as much as possible of local materials––"logs, . . . brick, and sawing lumber," with only some pine "sent up from Bismark," the fort included unframed buildings "built up of planks two inches thick by six inches wide, laid flat one upon another, forming a solid wall six inches in thickness."
With the sole exception of the officers' quarters, which consist of a ground floor and an attic, all the other buildings are of a single story ("Fort Custer," Wikipedia).
A large fort, it supported 10 companies, and six stables provided enough accommodations for six troops of cavalry.
Although most Native Americans in the region "had been been confined to reservations, when the fort was built" ("Fort Custer," Wikipedia), its purpose was "to navigate and manage the intensifying conflict between Native American tribes and the advancing American frontier" ("10 Historic Forts in Montana," Historic Forts), and its soldiers put down "an uprising at the Crow Agency in the fall of 1887," Colonel Nathan Dudley and his troops subsequently arresting "'Sword Bearer' and the Native Americans who had fired into the agency buildings on the night of September 30. On December 31, 1889."
Among the fort's troops were buffalo soldiers, as Native Americans had dubbed black soldiers ("Fort Custer," Wikipedia).
Fort C. F. Smith
Fort C. F. Smith (originally Fort Ransom) came into being on August 12, 1866, when it was built on the Powder River in lower Montana Territory, during Red Cloud's War, its mission to help to protect the Bozeman Trail against the Oglala Sioux, who viewed the trail as a violation of the 1851 Treaty of Fort Treaty.
The fort, built of adobe and wood, was burned down by Red Cloud's band of the Sioux after the Army abandoned it in 1868 ("Fort C. F. Smith [Fort Smith, Montana]," Wikipedia)
Fort Shaw (Camp Reynolds)
Fort Shaw (formerly Camp Reynolds) was established in 1867 to protect against Sioux and the Cheyenne hostilities ("Fort Shaw, Montana," Legends of America). Located "20 miles . . . upstream from the confluence of the Sun and Missouri rivers, . . .. it was about 5 miles . . . upstream from the point where the Mullan Road crossed the river ("Fort Shaw," Wikipedia).
As the Legends of America website points out:
During the 1876 campaign against the Sioux and Cheyenne, Colonel John Gibbon, the base commander, led the garrison up the Missouri River, procured reinforcements at Fort Ellis, Montana, rendezvoused with the forces of General Alfred Terry on the Yellowstone at the mouth of the Rosebud, and subsequently relieved the survivors of George Custer’s regiment at the Little Bighorn. The following year, troops from Forts Shaw, Ellis, and Missoula, again under Gibbon, defeated the non-treaty Nez Perce, retreating from Idaho to Montana at the Battle of the Big Hole.
As Camp Reynolds, the post consisted mostly of tents. As the camp was transformed into a fort, these shelters were gradually replaced by "log cabin housing," barracks, a storehouse, a hospital, a commissary, a guardhouse "with stone walls," officers' quarters, a chapel, school, library, bakery, ordnance, magazine, water tanks, washing tanks, a telegraph office, and other buildings.
Despite these improvements, the fort military use of the fort ended in 1892, after which part of it was turned over to the Fort Peck Indian boarding school and another part of it was reserved for agricultural use ("Fort Shaw," Wikipedia).
Fort Keogh
Officers' Quarters, Fort Keogh, 1989.
Established by Congress on July 22, 1876, Fort Keogh was built at the confluence of the Yellowstone River and the Tongue River, in Montana Territory, following the deaths of troops at the Battle of Little Bighorn (June 25-26, 1876), including those of Colonel George Armstrong Custer and Colonel Myles Keogh, after the latter of whom the post was named.
By the 1880s, most Native Americans had been removed from their lands to reservations, and, in 1909, two years after the fort's soldiers were relocated, it became an Army "remount station [which] supplied thousands of horses for World War I" and then a United States Department of Agriculture research center dedicated to improving "meat production and . . . quality" ("Fort Keogh," Fort Tours).
A "successor to to the Tongue River Cantonment, Fort Keogh . . . . [became] the largest in the territory, [with] sixty buildings once sprawled across the diamond-shaped grounds" ( "Fort Keogh," Montana History Portal).
Fort Connah
The British Hudson's Bay Company established a trading post in 1846 to prevent competition from American traders west of the Continental Divide. The post, initially named Fort Connah, was later renamed Fort Connen after a river valley in Scotland.
The main trade was in furs, buffalo meat, pemmican, buffalo skin saddle blankets, rawhide, and hair cordage. The company continued to operate during the fur trade era until its closure in 1871 due to encroaching settlement ("Fort Connah," Historic Montana).
