On the night of April 1, 1951, in six republics along the western edge of the Soviet Union, soldiers moved into villages and towns while the people inside their houses slept. They came with dogs and machine guns, and they carried lists on which names and addresses had already been written. The lists had been compiled over the preceding months by the Ministry of State Security, the agency the Soviets called the MGB. The men knocked, and when the doors opened, they read out an order. The order dictated that the family in front of them was being resettled, and the most important word in the documents was navechno, meaning forever.

The families on those lists were Jehovah’s Witnesses, and over the span of two days in the western republics, and a week later across Ukraine, Soviet security forces seized 9,793 people, loaded them into freight cars built for transporting cattle, and sent them east into Siberia. The MGB called it Operation North, and it ended up being the largest deportation of a single religious group in the history of the Soviet Union, carried out on the direct order of Joseph Stalin.

The Jehovah’s Witnesses were dispersed across the special settlements of Tomsk Oblast, Irkutsk Oblast, and Krasnoyarsk Krai, regions of forest and deep cold where the planners believed a small foreign faith could be left to die out among strangers. The families arrived to find snow still on the ground in late April, and many spent the first winter in shelters they dug into the earth, keeping themselves alive on nettles and the inner bark of trees. Of course, some had already died in the railcars, and others died in the initial months after their arrival.

The bare facts of the operation are striking enough on their own, but they sit within a larger irony that gives the story its shape. The Soviet state was an ascendant empire that had crushed far greater enemies than a few thousand pacifist believers, but it ended up proving unable to break the Jehovah's Witnesses.
