When Native and Metis unrest escalated into the Northwest Rebellion of 1885, settlers in southern Alberta's cattle country were terrified. Three major First Nations bordered their range, and war seemed certain. In anticipation, 114 men mustered to form the Rocky Mountain Rangers, a volunteer militia charged with ensuring the safety of the open range between the Rocky Mountains and the Cypress Hills. The Rangers were a motley crew, from ex-Mounties and ex-cons to retired, high-ranking military officials and working, ranch-hand cowpokes. Membership qualifications were scant: ability to ride a horse, knowledge of the prairies, and preparedness to die.
