About Aleksei Brusilov
Aleksei Alekseyevich Brusilov (, US also; Russian: Алексе́й Алексе́евич Бруси́лов, IPA: [ɐlʲɪkˈsʲej ɐlʲɪkˈsʲejɪvʲɪdʑ brʊˈsʲiɫəf]; 31 August [O.S. 19 August] 1853 – 17 March 1926) was a Russian and later Soviet general most noted for the development of new offensive tactics used in the 1916 Brusilov offensive, which was his greatest achievement. Born into an aristocratic military family, Brusilov trained as a cavalry officer, but by 1914 had realized that cavalry was obsolete in an offensive capacity against modern weapons of warfare such as mass adoption of rifled guns, machine guns, and artillery. He is considered a very outstanding general who won many battles against the Austro-Hungarian army. His offensive in 1916 was the final major success of the Tsarist army. In the government, this offensive meant the transfer of the strategic initiative to the Russians and the beginning of preparations for the general offensive of 1917, which, however, was disrupted by the revolution. Despite his noble status and prominent role in the Imperial Russian Army, he sided with the Bolsheviks in the Russian Civil War and aided in the early organization of the Red Army until retiring in 1924. Brusilov is one of the prominent Russian commanders in history. Although not regarded as especially brilliant, he was pragmatic and open to change based on experience; his eponymous offensive succeeded in part from his willingness to properly train and prepare his troops, including in modern artillery and air reconnaissance. At the end of his first year, a tutor remarked of Brusilov, "his nature is brisk and even playful, but he is good, straightforward and clean-living. His unit operated on the Southern Front in the Caucasus, and took part in the assault of the fortress of Ardagan (now Ardahan, Turkey), for which Brusilov was awarded the Order of Saint Stanislav, 3rd Class. In 1881, Brusilov became a student at the Cavalry Officer School in Saint Petersburg and two years later was appointed as a riding instructor there.
