Western democracies have expressed concern and outrage, at least verbally, over the Novichok poisoning of Alexei Navalny—and this is clearly right and necessary. But much less attention is being paid to the case of Yuri Dmitriev, a tenacious researcher and activist who campaigned to create a memorial to the victims of Stalinist terror in Karelia, a province in Russia’s far northwest, bordering Finland. He has just been condemned on appeal by the Supreme Court of Karelia to thirteen years in a prison camp with a harsh regime.

The hearing was held in camera, with neither him nor his lawyer present. For this man of sixty-four, this is practically equivalent to a death sentence, the judicially sanctioned equivalent of a drop of nerve agent.

After an initial charge of child pornography was dismissed, Yuri Dmitriev was convicted of sexually assaulting his adoptive daughter. These defamatory charges appear to be the latest fabrication of a legal system in thrall to the FSB—a contemporary equivalent, here, of the nonsensical slander of “Hitlerian Trotskyism” that drove the Great Terror trials. It is these same charges, probably freighted with a notion of Western moral decadence in the twisted imagination of Russian police officers, that were brought in 2015 against the former director of the Alliance Française in Irkutsk, Yoann Barbereau.

I met Yuri Dmitriev twice: the first time in May 2012, when I was planning the shooting of a documentary on the library of the Solovki Islands labor camp, the first gulag of the Soviet system; and the second in December 2013, when I was researching my book Le Météorologue (Stalin’s Meteorologist, 2017), on the life, deportation, and death of one of the innumerable victims murdered by Stalin’s secret police organizations, OGPU and NKVD.

In both cases, Dmitriev’s help was invaluable to me. He was not a typical historian. At the time of our first meeting, he was living amid rusting gantries, bent pipes, and machine carcasses, in a shack in the middle of a disused industrial zone on the outskirts of Petrozavodsk—sadly, a very Russian landscape. Emaciated and bearded, with a gray ponytail, he appeared a cross between a Holy Fool and a veteran pirate—again, very Russian. He told me how he had found his vocation as a researcher—a word that can be understood in several senses: in archives, but also on the ground, in the cemetery-forests of Karelia.

In 1989, he told me, a mechanical digger had unearthed some bones by chance. Since no one, no authority, was prepared to take on the task of burying with dignity those remains, which he recognized as being of the victims of what is known there as “the repression” (repressia), he undertook to do so himself. Dmitriev’s father had then revealed to him that his own father, Yuri’s grandfather, had been shot in 1938.

“Then,” Dmitriev told me, “I wanted to find out about the fate of those people.” After several years’ digging in the FSB archive, he published The Karelian Lists of Remembrance in 2002, which, at the time, contained notes on 15,000 victims of the Terror.
