Fort Whoop-Up and the Prairie Whisky Trade

Fort Whoop-Up was a trading post founded in 1869 by Montana traders near present-day Lethbridge, Alberta, where whisky was exchanged for bison robes. Its history connects the cross-border robe trade, violence against Indigenous communities and the arrival of the North-West Mounted Police, who reached the notorious fort on 9 October 1874 and found it almost empty. [1][3][4]

Fort Whoop-Up and the prairie whisky trade

The fort stood at the junction of the St Mary and Belly rivers, the latter now called the Oldman. Its founders were John J. Healy and Hamilton, two traders supplied from Fort Benton, Montana. The Galt Museum and Archives records that they took supplies north from Fort Benton in December 1869. [1][3]

Their first post, Fort Hamilton, was a small building with six rooms. It soon became known as Fort Whoop-Up, although the familiar name should not obscure its practical purpose: The Canadian Encyclopedia describes an illicit trade in whisky for bison robes with Cree and Blackfoot people on the southern prairies. [1][3]

Fire badly damaged the first building after one trading season, and work on a larger replacement began in 1870. According to the Galt Museum, William Gladstone, a former Hudson’s Bay Company carpenter, built the second fort with a crew of about forty, mostly Métis men. That workforce belongs in the fort’s history alongside the traders whose names usually introduce it. [1][3]

Story box: The fort the police found almost empty

Verdict: Documented

Claim: The police reached Fort Whoop-Up on 9 October 1874 and found it almost empty, without whisky. What the record shows: The RCMP chronology and Galt Museum account support this arrival, rather than a confrontation with traders. Evidence against or gap: None found in the supplied record. Earliest known source: Not established from the sources checked. Sources: RCMP chronology and Galt Museum history, checked 7 November 2026. [3][4]

Robes, barrels and the route from Montana

Bison robes were the main commodity, according to the Galt Museum. Its account places Whoop-Up within a larger trading network: at the robe trade’s peak, up to 75,000 robes passed through Fort Benton each year. That figure describes Fort Benton’s trade, not the number handled at Whoop-Up. [3]

The whisky was kept in a large barrel and dispensed by the jug or cupful. The museum describes diluted spirit that might contain chewing tobacco, burnt sugar, tea or ink for flavour and colour. These are historical descriptions of adulteration, not a recipe or evidence of a consistent product. [3]

Calling it “trade whisky” therefore identifies what traders exchanged, rather than establishing its composition. The barrel at Whoop-Up belongs to a history of supply, barter and adulteration, not to a documented account of distillation or a particular whiskey style. The sources here establish a trading post, not a distillery. [1][3]

The Galt Museum says American law banned alcohol trading in Montana’s Indian Country, which pushed traders north. The Canadian Encyclopedia calls the prairie whisky trade illicit, while Parks Canada’s designation describes traders dealing in contraband liquor and firearms between 1869 and 1874. Its account associates that trade with harm to Indigenous communities. This was not simply an adventurous route by which American whiskey reached a new market. [1][2]

Cypress Hills: violence and its aftermath

On 1 June 1873, American wolf hunters attacked a Nakoda, or Assiniboine, camp in the Cypress Hills, near Farwell’s and Solomon’s trading posts. Parks Canada describes a dispute over horses and records that the camp was close to the posts of two whiskey traders. [5][7]

The Canadian Encyclopedia gives a fuller account: wolf hunters from Fort Benton believed Cree people had stolen their horses, and all parties had been drinking illegal whisky before the violence. Parks Canada records that the Nakoda had travelled south because famine followed the disappearance of large game. [7][8]

Many Nakoda were killed, including Elders, warriors, women and children. The exact death toll is not reliably established: Parks Canada gives no number, while The Canadian Encyclopedia reports at least twenty deaths. The massacre happened at Cypress Hills, not Fort Whoop-Up, but belongs to the wider history of the prairie whisky trade. [5][7][8]

The attempts to prosecute those responsible failed. In June 1875, Macleod and Inspector A. G. Irvine went to Fort Benton and arranged the arrest of seven men. An extradition hearing at Helena the following month ended with the prisoners freed; Macleod himself was briefly jailed on a charge of false arrest. [6]

Three men taken in Canada were tried in Winnipeg in June 1876 and acquitted. All charges were dropped in 1882. Parks Canada’s conclusion is direct: the government did not bring the perpetrators to justice. Descendants in the Carry the Kettle First Nation regard the massacre site as sacred ground. [7][8]

Did the massacre create the Mounties?

The dates distinguish the force’s creation from the urgency of sending it west. The RCMP chronology records that Parliament passed the bill creating the North-West Mounted Police on 23 May 1873, before the Cypress Hills Massacre on 1 June. Parks Canada says the massacre “hastened the dispatch” of the police. [4][5]

Verdict: Disputed

Claim: The massacre’s role in the creation and dispatch of the police is disputed. What the record shows: Parliament passed the bill before the massacre. Parks Canada says the massacre hastened dispatch, while The Canadian Encyclopedia says it reinforced a need the government was already addressing. Evidence against or gap: Approval and dispatch were separate events. Earliest known source: Not established from the sources checked. Sources: RCMP chronology, Parks Canada designation and The Canadian Encyclopedia, checked 7 November 2026. [4][5][8]

The force was formally established by an Order in Council on 30 August 1873. Its March West began at Fort Dufferin, Manitoba, on 8 July 1874, with 318 men under George Arthur French and James F. Macleod. These were separate stages, not one immediate response to the massacre. [4][6]

The arrival at Whoop-Up

Jerry Potts led the police to Fort Whoop-Up on 9 October 1874. Their almost empty destination makes a striking contrast with the fort’s reputation, but the absence of whisky that day did not erase the trade that had made the post notorious. [3][4]

By the end of October, Fort Macleod had been established on the Oldman River at a site selected by Potts. The Dictionary of Canadian Biography describes Macleod’s work suppressing the whisky trade and records the cooperation of Blackfoot chiefs Crowfoot and Red Crow. [6]

According to the Galt Museum, the police had the whisky trade under control by the end of 1875. That is a broader development than their arrival at one fort, and it should not be confused with successful prosecution for the Cypress Hills killings. The suppression of trade and the failure of justice were distinct outcomes. [3][7][8]

A short chronology

What survives, and what is reconstructed

The robe trade was finished by 1881, according to the Galt Museum. Part of Fort Whoop-Up served as a police outpost, but settlers later burned the fort and removed remains for lumber and metal. Parks Canada records only a stone-lined well surviving above ground at the original site. [1][2][3]

The original site received National Historic Site designation on 28 October 1963. The fort built in Lethbridge’s Indian Battle Park in 1967 is a replica of the second fort, redeveloped in the 1980s, not the surviving original. Keeping those places separate matters when looking at photographs or accounts of a visit. [1][2][3]

Parks Canada has also identified the Whoop-Up designation for review, a process whose reasons can include outdated language or factual errors. Its plaque is a source for how the fort has been commemorated, but not a substitute for examining the trade, Indigenous experiences and the chronology separately. [2]
