Samsonov fought in the Russo-Turkish War, 1877–78. After this war he attended the Nikolaevsky Military Academy in St. Petersburg. On November 4, 1888, he was appointed senior aide to the staff of the 20th Infantry Division, and from July 10, 1885, to February 4, 1889, served as Senior Staff Adjutant to the Caucasus Grenadier Division. From March 11, 1890, through July 26, 1896, he worked at various assignments at the Warsaw Military District. He subsequently became commandant of the Elisavetgrad Cavalry School. During the Boxer Rebellion (1900), Samsonov commanded a cavalry unit. During the Russo-Japanese War (1904–1905), Samsonov commanded a cavalry brigade of the Ussuri Siberian Cossack Division. He was promoted to command all Russian cavalry forces in the First Siberian Army Corps following the Russian defeat at the Battle of Telissu. His forces subsequently protected the Russian flanks at the Battle of Liaoyang. Through these conflicts Samsonov gained a reputation as an energetic and resourceful leader, but some observers criticized his strategic abilities. He had no command experience preparing him to command an army of thirteen divisions.
