[A]ll the non-Stalinist versions concur in the following: the generals did indeed plan a coup d'état... The main part of the coup was to be a palace revolt in the Kremlin, culminating in the assassination of Stalin. A decisive military operation outside the Kremlin, an assault on the headquarters of the G.P.U., was also prepared. Tukhachevsky was the moving spirit of the conspiracy... He was, indeed, the only man among all the military and civilian leaders of that time who showed in many respects a resemblance to the original Bonaparte and could have played the Russian First Consul. The chief political commissar of the army, Gamarnik, who later committed suicide, was initiated into the plot. General Yakir, the commander of Leningrad, was to secure the co-operation of his garrison. Generals Uberovich, commander of the western military district, Kork, commander of the Military Academy in Moscow, Primakow, Budienny's deputy in the command of the cavalry, and a few other generals were also in the plot.
