Cypress Hills Massacre

The Cypress Hills Massacre took place on June 1, 1873, near Battle Creek in the Cypress Hills region of what was then Canada's North-West Territories (now Saskatchewan). The incident arose after a party of Canadian Red River Métis and American wolf hunters, led by Thomas W. Hardwick and John Evans, lost their horses while camped on the Teton River in Montana Territory. Believing the horses had been stolen by Indigenous people, the men sought help from authorities at Fort Benton, Montana Territory, who refused. Hardwick then organized his own party of 13 men to recover the horses, traveling north across the border.

The group arrived at Abe Farwell's trading post in the Cypress Hills, where they were joined by George Hammond, who had been selling whisky in the area. Farwell told the men that Little Soldier, leader of a nearby Assiniboine band, had not taken their horses. After a search found no evidence implicating Little Soldier's group, the wolfers spent the evening and following morning drinking whisky with recently arrived Métis freighters at Farwell's post.

The next morning, Hammond claimed one of Little Soldier's men had stolen his horse a second time and pressed the group to confront the Assiniboine camp. Accounts of what followed are inconsistent, as no fully reliable testimony survives. Farwell testified he attempted to prevent violence. Little Soldier denied taking the horse, saying it was grazing nearby, and offered two horses as security. Tensions escalated as both groups had been drinking, and Assiniboine men began preparing for potential conflict. The wolfers took up a defensive position along a riverbank. Farwell attempted further negotiation, but Hammond fired his rifle, after which the wolfers fired volleys into the camp. The Assiniboine returned fire but could not sustain the fight against the wolfers' protected position.

Casualty figures vary across accounts. One wolfer, Ed Legrace, was killed; according to a personal account by Donald Graham, who traveled with the wolfers, thirteen of Little Soldier's men were killed. The wolfers buried Legrace in a cabin and burned it.

News reached Ottawa in late August 1873, prompting Canada to seek extradition of those involved from the United States. In December 1874, NWMP Assistant Commissioner James Macleod was permitted to investigate in Helena, Montana Territory. Seven arrests were made, two men escaped custody, and the rest were released for lack of evidence; the American commissioner denied extradition due to conflicting testimony. In June 1876, two traders and a wolfer were arrested and tried in Winnipeg but were acquitted due to insufficient evidence; the case was formally dropped in 1882. No convictions resulted from the prosecutions.

The massacre is cited as a catalyst for the accelerated creation of the North-West Mounted Police, established by order-in-council on September 25, 1873. The massacre site was designated a National Historic Site of Canada in 1964, and related artifacts are preserved at Fort Walsh National Historic Site.
