Early life

In early 1805 he retired from the army and became an official in the Ministry of Commerce, but returned on 14 August that year, receiving the position of a staff Rotmister in the Izumsk Hussar Regiment on the 26th. He was brother to Russian poet Andrey Kaysarov, and later married Varvara Yakovlevna Lanskaya, niece of Alexander Lanskoy.^[2]

On 2 October 1821, he had been given command of the 14th Division, and promoted to lieutenant general on 13 January 1826. In March 1829, he became chief of staff to the 1st Army.^[6] In 1830 and 1831, he took part in the suppression of the Polish insurrection of 1830-31; his forces besieged and eventually captured the Zamość Fortress. On 25 March 1831, he was instated as commander of the 3rd Infantry Corps (later to become the 5th Infantry Corps). On 18 December 1833, he was promoted to General of the Infantry. In 1835, he was transferred command the 4th Infantry Corps. On 5 November 1842, he retired from the armed forces due to poor health, spending the remainder of his days as a member of the Governing Senate of the Russian Empire. He died in Nice.^[7] He is buried in the cemetery of the Church of the Nativity of the Blessed Virgin, near the Far Caves of the Kiev Pechersk Lavra.^[8]
