Johann von Michelsohnen

Ivan Ivanovich Michelson (sometimes transliterated as Mikhelson; Russian: Ива́н Ива́нович Михельсо́н; German: Johann von Michelsohnen; 3 May 1740 – 17 August 1807) was a Baltic-German military commander who served in the Russian Imperial Army. He was a prominent general in several wars, but his most noted contribution was his critical role in suppressing Pugachev's Rebellion.

Michelson was born in Revel in the Governorate of Estonia to a family of noble rank. He was a practicing Lutheran and a Mason. His early military career saw him serve as a cavalry officer in many conflicts: the Seven Years' War, the Russo-Turkish War of 1768-1774, and the war against the Bar Confederation.

By the end of 1773 Michelson held the rank of Lieutenant-Colonel of Saint-Petersburg Regiment of Carabineers, and, after the new force arrived in rebel-occupied territory, was given command over a force of soldiers to fight against the rebels led by Yemelyan Pugachev, who by this time had gained a fearsome reputation and defeated several expeditions sent against him by the government. Soon enough events turned around due to Michelson's exceptional resolve, especially his indefatigability when confronting followers of the rebellion, whom he crushed wherever he encountered them. His most decisive action was at the Battle of Kazan, where he led the relief force to the besieged city. By the time Michelson had arrived on July 13, Pugachev's army had already surrounded the city's Kremlin where the remaining defenders and loyal citizens had taken refuge. Michelson launched a determined strike on the rebels, and thereafter pursued them across the right bank of the Volga River. He refused to relent, and as the rebels attempted to regroup near Tsaritsyn, drove his small army of under 5000 men to engage Pugachev near Chyorny Yar on August 25, where he annihilated a force of 10,000 rebels, killing 2000 and capturing 6000 more, suffering only 90 casualties to his forces in the process. Michelson had managed to end any major threat of the rebellion reemerging and assaulting the Russian interior.
