Yemelyan Pugachev
Yemelyan Ivanovich Pugachev () (c. 1742 – ) was a Russian Cossack who led a great popular insurrection during the reign of Catherine the Great, claiming to be her late husband, Emperor Peter III. Alexander Pushkin wrote a notable history of the rebellion, "The History of Pugachev", and he recounted some of the events in his novel "The Captain's Daughter" (1836).
Battle of Kazan (1774)
In the evening governmental troops from Ufa under Johann Michelson reached Kazan. A harsh battle took place at the modern Gogol street, but neither side won. Pugachev retreated to Savinovo and Sukhaya Reka villages. On 13 July he tried to prevent the end of the siege of the citadel, but under the pressure of Michelson and Potyomkin the rebels were defeated and were forced to retreat. On 15 July Pugachyov's army of 15,000 was defeated in the battle of Arsk Field. Pugachev with 500 men escaped to Tsaryovokokshaysk, to cross the Volga on 18 July and to continue his struggle then. Michelson didn't follow him, as government forces had no horses.
