On November 4, 1774, Pugachev and his rolling cage arrived in Moscow. Six weeks of interrogation began. The empress was resolved to satisfy her doubts about the rebellion; she still could not believe that an illiterate Cossack had instigated the revolt on his own. Voltaire lightheartedly proposed that Pugachev be asked, “Sir, are you master or servant? I do not ask who employs you but simply whether you are employed.” Catherine wanted more: if there were employers, she wished to know their identities. Catherine carefully monitored the proceedings, but despite the intensity of her curiosity, she refused to allow the use of the rack. Before the investigation began, she had written to Prince Volkonsky, governor-general of Moscow, “For God’s sake, refrain from all questioning under torture which always obscures the truth.” Behind this command was not only her opposition to barbarism but also political calculation. The rebellion appeared to have spent itself, but that had also seemed the case before the surprise assault on Kazan. Perhaps, even now, there might be another leader waiting to revive the rebellion. Torture of the man whom many peasants had believed was a tsar could provide another spark. Although she was intrigued by the impostor’s character and motives, she had no desire to see him. She was already planning a lengthy visit to Moscow to celebrate the peace with Turkey, and she wished the whole Pugachev business to be finished before she arrived. As for foreign influence, even before the interrogators were finished Catherine concluded that there was none. To Voltaire she wrote, “The Marquis de Pugachev has lived like a scoundrel and will die like a coward. He cannot read or write, but he is a bold and determined man. So far there is not a shred of evidence that he was the instrument of any foreign power. It is to be supposed that Monsieur Pugachev is a master brigand and no man’s servant. No one since Tamerlane has done more harm than he.”
On December 5, the work of the interrogating commission was completed. Pugachev had confessed and expressed hope for mercy, but a death sentence was inevitable. Nevertheless, Catherine wrote to Voltaire, “If it were only me he had harmed, his hopes could be justified and I should pardon him, but this trial involves the empire and its laws.” To dissociate herself publicly from the trial and execution, she privately sent Procurator General Vyazemsky to Moscow with instructions to end the affair quickly. She followed by writing to the Moscow governor, Prince Volkonsky: “Please help to inspire everyone with moderation both in the number and in the punishment of the criminals. The opposite will be regrettable to my love for humanity. We do not have to be clever to deal with barbarians.”
Vyazemsky did his best to obey. To avoid public pressure in the vengeful atmosphere of Moscow, he established a special court made up of high officials and members of the Holy Synod. The trial was conducted secretly in the Kremlin on December 30 and 31. Pugachev was brought before the court on the second day. He fell on his knees, admitted again that he was Emelyan Pugachev, acknowledged his crimes, and declared that he repented before God and the all-merciful empress. When he was led away, the judges decided that he should be quartered alive and then beheaded. But when the same sentence was awarded to one of his lieutenants, several judges protested that the sentence on Pugachev should be more severe and painful than that on others. “So they wanted to break Pugachev on the wheel,” Vyazemsky wrote to Catherine, “in order to distinguish him from the rest.” Eventually, the procurator general persuaded the court to leave Pugachev’s sentence as it was. Knowing that the empress would never accept the public spectacle of Pugachev being quartered alive, Vyazemsky secretly arranged with Moscow’s chief of police to have the executioner “accidentally” behead Pugachev first and afterward chop off his hands and feet. The execution took place before an immense crowd in a Moscow square on January 10, 1775. Pugachev crossed himself and laid his head on the block. Then, to the indignant rage of spectators who included noblemen come to savor their revenge, the executioner seemed to bungle his job by immediately decapitating Pugachev; many were convinced that either the executioner was incompetent or that he had been bribed by someone. Four of Pugachev’s lieutenants were quartered first, then beheaded. The lieutenants who had betrayed and handed over their chief were pardoned.
