On April 30, 1938, a top Yezhov deputy at the NKVD, Zakovsky, was arrested. He had been a Stalin favorite, the operative who had helped oversee Stalin’s rare trip to the interior of the country (Siberia, in 1928), and had been appointed to exact retribution in Leningrad in the aftermath of Kirov’s assassination. At the January 24, 1938, Moscow meeting of all top NKVD officials, Zakovsky’s maniacal work had been praised to the skies, especially his high percentage of extracted confessions, which had brought a promotion to the central NKVD in Moscow.8 (Zakovsky was said to have boasted that he could make Karl Marx confess to being Bismarck’s agent.)9 Yezhov, forced to explain Zakovsky’s arrest to other NKVD operatives, averred that his award-winning underling had manufactured “pumped-up cases” and set outrageously high arrest quotas in Leningrad. Of course, these were the very reasons Zakovsky had been named a deputy chief of the USSR NKVD. Yezhov, moreover, told the assembled operatives that the rabid arrests would continue, further reinforcing the impression that Zakovsky had been destroyed against Yezhov’s wishes.10 A sense of doom began to close in on the secret police. On the eve of Zakovsky’s removal, at Frinovsky’s dacha, Vasily Karutsky, an operative recently promoted to the central NKVD, had “called Zakovsky a traitor and spy and said that he would soon be arrested” to Zakovsky’s face, according to an eyewitness, who added that “Zakovsky, for his part, had called Karutsky a traitor and said that if he himself were arrested, it would only be after Karutsky.”11 Karutsky proved correct: he succeeded Zakovsky at the Moscow NKVD. On the second day on the job, he shot himself.12
Clouds darkened over the core Yezhovite group in the NKVD, the “clan” of Yevdokimov, whose collective promotions had facilitated the annihilation of the Yagodaites. Already, back on October 19, 1937, the Yevdokimov loyalist Alexander Kaul had been arrested in the North Caucasus, and although Frinovsky managed to get him transferred to Moscow and placed in the internal prison (to sit quietly without being interrogated), in fall 1937,
Yevdokimov’s removal to Moscow and the accompanying onslaught against his cadres back in Rostov—which betrayed Stalin’s hand—manifestly threatened Yezhov. Reasoning that even higher numbers of “enemies” could win back Stalin’s favor, Yezhov urged Frinovsky to notch up the terror, but even Frinovsky began to drag his feet in implementing Yezhov’s orders.15 From March through May 1938, Kaganovich, who had previously felt compelled to collude in the execution of most of his own subordinates, now did not even respond to NKVD materials sent to him about the need for further arrests in rail transport; when those arrests were force ordered, Kaganovich sabotaged the NKVD’s dirty work.16 Yezhov threatened Molotov with arrest, telling him, “In your shoes, Vyacheslav Ivanovich, I would not be posing such questions to the competent organs. Do not forget that a chairman of the Council of People’s Commissars, A. I. Rykov, was already in my institution.” But Molotov went to Stalin, who advised him to demand an apology from Yezhov, which Molotov obtained.17 Yezhov appeared to be a wounded animal, and the other animals were acting accordingly. But a secret police boss without fangs is destabilizing for a regime.
