Stuart's Stranglers was a well-known vigilante group in Montana that was founded in 1884 and led by Granville Stuart in response to widespread livestock theft at that time. They were also less commonly known as the "Montana Stranglers."
Granville Stuart originally organized a group of ranchers and cowboys in response to the theft of his stallion and 35 steers. The 14 men who gathered at his ranch in the Musselshell region called themselves a "Vigilante Committee," akin to the vigilance committees that formed in the mining camps of western Montana. They became known as "Stuart's Stranglers."
Their missions were directly led by William "Floppin Bill" Cantrell. Throughout their short existence their membership during chases would fluctuate between 17 and 40 men, depending on the location of the thieves and the day of the week.
Stuart's Stranglers tracked down livestock thieves in Montana. The men they caught were either shot in a gun fight or lynched. Many of the bodies they hung were found with place cards on their person that usually read "Horse Thief" or "Cattle Thief." They were known for being extremely deadly and efficient. Not only did the group kill rustlers and thieves during their search, but also illegal range squatters scattered throughout the frontier which would become a Montana range war.
In July 4, Stuart and his group were hunting down Stringer Jack and his gang of rustlers in Musselshell River. Jack's gang managed to get across the river with some stolen horses, and the Stranglers were hotly and stealthily in pursuit. As the gang rested in a log cabin owned by Old Man James, the Stranglers surrounded the place, released the horses so the men inside couldn't escape, and promptly asked them to surrender. The gang however, remained defiant, and a bloody gunfight soon erupted. During the heat of the battle, the Stranglers set fire to the cabin, resulting in nine rustlers dead in the ensuing shootout. Stuart described the battle:
"Two of the vigilantes crawled up and set fire to the hay stack and the cabin. The men inside stationed themselves at port holes and kept up the fight until they were all killed or burned up. The cabin burned to the ground. The tent was near the river bank and almost surrounded by thick brush and it was easier to escape from it than to get out of the cabin. Stringer Jack crawled under the tent and reached a dense clump of willows from which he made his last stand. Dixie Burr, his arm smashed by a rifle bullet, hid in an old dry well until dark and then made his escape. Rose, Nickerson, Edwards and Swift Bill also slipped out of the tent and got away in the dark. Every one of the outlaws in the gun battle at Bates Point was either killed or wounded with the exception of Edwards and Nickerson, who—for the time being—got away unscathed."
