The idea of impersonating the late Emperor
Peter III occurred to Pugachev early on, even before he reached the Yaik Cossacks. It is of no surprise, given another recent peasant impersonator, Fedot Bogmolov, and
Russia's history of impersonators. Pugachev, posing as a wealthy merchant, reportedly tested the feelings of the Cossacks at the
Yaitsk by suggesting that he led a mass exodus into Turkey. When the majority seemed to agree with his plan, he deemed it the right time to begin his rebellion. Though he was arrested shortly after once again, and this time held for five months at
Kazan, he escaped once more and returned to the Yaitsk to start his revolt. By promising to return several privileges to the Cossacks and to restore the Old Belief, he was able to gain the support he needed to promote his identity as Peter III. The story of Pugachev's strong resemblance to the Tsar Peter III, who in 1762 was overthrown and murdered by his wife's supporters, the future empress Catherine II, comes from a later legend. Pugachev told the story that he and his principal adherents had escaped from the clutches of Catherine. Having amassed an army through propaganda, recruitment and promise of reform, Pugachev and his generals were able to overrun much of the region stretching between the
Volga River and the
Urals. Pugachev's
greatest victory of the insurgency was the taking of
Kazan. As well as amassing large numbers of Cossacks and peasants, Pugachev also acquired artillery and arms and was able to supply his force better than the Russian army would have predicted. . In response, General
Peter Panin set out against the rebels with a large army, but difficulty of transport, lack of discipline, and the gross insubordination of his ill-paid soldiers paralysed all his efforts for months, while Pugachev's innumerable and ubiquitous bands gained victories in nearly every engagement. Not until August 1774 did General
Michelsohn inflict a crushing defeat upon the rebels near
Tsaritsyn, when they lost; ten thousand were killed or taken prisoner. Panin's savage reprisals, after the capture of
Penza, completed their discomfiture. On 14 September 1774, Pugachev's own Cossacks delivered him to Yaitsk.
Alexander Suvorov had him placed in a metal cage and sent first to
Simbirsk and then to Moscow for a public execution, which took place on . In
Bolotnaya Square in the centre of Moscow, he was decapitated and then drawn and quartered in public. ==Legacy==
