Stalin and Bukharin prepared themselves for a last decisive campaign against the internal party opposition. They had always hated Trotski and, in their private correspondence, they took delight in their growing success in humbling him. But they also retained a certain fear of him. They knew him to be talented and determined; they were aware that he had kept a personal following in the party. Trotski remained a dangerous enemy. They had less respect for Zinoviev but saw that he too was still a menace. Even more perilous was the effect of the rapprochement of Trotski and Zinoviev. As Zinoviev criticised Bukharin and Stalin from a left-wing position, the differences among the oppositionists lessened. A United Opposition was formed in mid-1926. When Stalin heard that Krupskaya had sympathies with Zinoviev, he wrote to Molotov: ‘Krup-skaya’s a splitter. She really needs a beating as a splitter if we wish to conserve party unity.’12 Two years earlier he had welcomed her support as he defended himself against the effects of Lenin’s Testament. Having survived that emergency, he intended to deal with her as severely as with other leading members of the United Opposition.
By mid-1926 the scene was set for the settling of accounts and Stalin was spoiling for a fight. When Trotski muttered to Bukharin that he expected to have a majority of the party on his side, the General Secretary wrote to Molotov and Bukharin: ‘How little he knows and how low he rates Bukharin! But I think that soon the party will punch the snouts of Tr[otski] and Grisha [Zinoviev] and Kamenev and will turn them into renegades like Shlyapnikov.’13 He accused them of behaving even less loyally than Shlyapnikov’s Workers’ Opposition. They needed to be confronted. Zinoviev should be sacked from the Politburo. The ascendant party leadership need have no fear: ‘I assure you that this matter will proceed without the slightest complications in the party and the country.’14 Zinoviev should be picked off first. Trotski could be left for later.15
The Stalin group in the leadership was by then well organised. Stalin himself could afford to stay by the Black Sea while, on 3 June 1926, a terrific dispute raged for six hours about theses proposed by Zinoviev.16 Stalin wanted total control of his group. He wanted to be kept abreast of developments and relayed regular instructions to his subordinates. But he had created a system which permitted him to be the master even while he was on vacation. He asserted himself to an ever greater extent. In September 1926 he wrote to Molotov indicating substantial reservations about his ally and supposed friend Bukharin: ‘Bukharin’s a swine and surely worse than a swine because he thinks it below his dignity to write a couple of lines.’17 Around that time he also said of his associate Mikoyan: ‘But Mikoyan’s a little duckling in politics, an able duckling but nevertheless a duckling.’18 From all this it appeared that Stalin saw himself as the single indispensable force in the campaign against the United Opposition. In his own eyes, no one else could successfully coordinate and lead the ascendant party leadership in the coming factional conflicts. He made it his aim to send Trotski and Zinoviev down to permanent defeat.
Yet the strain of constant polemics took its toll on him. Free in his accusations against the United Opposition, he was hurt by the tirade of personal abuse he himself had to endure. He was an extremely sensitive bully. When the situation got too much for him, he followed his pattern in the early years after October 1917 and sought to resign. On 27 December 1926 he wrote to Sovnarkom Chairman Alexei Rykov saying: ‘I ask you to release me from the post of Central Committee General Secretary. I affirm that I can no longer work at this post, that I’m in no condition to work any longer at this post.’ He made a similar attempt at resignation on 19 December 1927.19 Of course he wanted to be persuaded to withdraw such statements of intent — and indeed his associates did as he wished. But the mask of total self-control and self-confidence had slipped in these moments.
