During late August and September, the Bolsheviks enjoyed a sudden growth in strength, following their failures during the summer. On August 31, they finally achieved a majority in the Petrograd Soviet, and on September 5, they won a similar victory in the Moscow Soviet. Lenin, fearing arrest after the events of July, continued to hide in rural areas near the Finnish border. As time went on, he become more and more impatient and began calling urgently for the ouster of the provisional government.
Although Prime Minister Alexander Kerensky’s authority was faltering, the provisional government was coming closer to organizing the Constituent Assembly, which would formally establish a republican government in Russia. Elections for the assembly were scheduled for November 12. Lenin knew that once this process started, it would be far more difficult to seize power while still preserving the appearance of legitimacy. If there were to be another revolution, it had to take place before then.
Before a revolution could happen, Lenin faced considerable opposition from within his own party. Many still felt that the timing was wrong and that Lenin had made no serious plans for how the country would be administered after power was seized. On October 10, shortly following Lenin’s return to Petrograd, the Bolshevik Party leadership (the Central Committee) held a fateful meeting. Few details of this meeting have survived, but it is known that Lenin delivered an impassioned speech in which he restated his reasons for staging the uprising sooner rather than later. Most of those present—only twelve men in all—initially were reluctant. Nevertheless, by the end of the meeting, Lenin had talked all but two of them into approving an armed uprising to oust the provisional government. What had yet to be decided was precisely when the revolution would happen.
During the next two weeks, Lenin’s followers remained holed up in their headquarters at the Smolny Institute, a former school for girls in the center of Petrograd, where they made their final plans and assembled their forces. A Second Congress of Soviets was now in the works, scheduled for October 25, and the Bolsheviks were confident that they would have its overwhelming support, since they had taken pains to invite only those delegates likely to sympathize with their cause.
Just to be sure, however, the Bolsheviks decided to hold the revolution on the day before the meeting and then to ask the Congress to approve their action after the fact. The two Bolshevik leaders who had voted against the uprising after the October 10 meeting, Lev Kamenev and Grigory Zinoviev, continued to protest the plan and resist Lenin’s preparations. However, at the last moment, they suddenly reversed their position so as not to be left out.
By this point, the Bolsheviks had an army of sorts, under the auspices of the Military Revolutionary Committee, technically an organ of the Petrograd Soviet. Lenin and the other Bolshevik leaders, however, knew that these troops were unreliable and had a tendency to flee as soon as anyone fired at them. However, they expected that at least the main Petrograd garrison would support them once they saw that the Bolsheviks had the upper hand.
