Originally formed in the winter of 1864-5 to prevent Canadian-based raids by Southern Confederates on the United States, the Canadian secret police force soon became preoccupied with preventing American-based raids by Fenians on Canada. Its operations were directed against not only American Fenians, but also their supporters within Canada -- Irish Catholic revolutionaries who planned to support the invaders by such methods as cutting telegraph wires, blowing up bridges, burning down buildings and taking its political leaders hostage. One of the greatest challenges facing the government was to identify, isolate and undermine the revolutionaries without alienating members of the Irish Catholic community in general. How did the government and the secret police force respond to that challenge, and what does that response tell us about the relationship between security and liberty in mid-nineteenth century Canada?
