Fabian Wilhelm von Osten-Sacken

Prince Fabian Gottlieb von der Osten-Sacken (Russian: Фабиан Вильгельмович Остен-Сакен) (20 October 1752 – 7 September 1837) was a Baltic-German Field Marshal who led the Russian army against the Duchy of Warsaw and later governed Paris during the city's brief occupation by the anti-French coalition.

Osten-Sacken was born in Reval, in present-day Estonia, into the family of Baron Wilhelm-Ferdinand von der Osten-Sacken, who prior to his death in 1754, was a Captain-adjutant of Count Munnich. Baron Osten-Sacken was only two when his father died and spent his childhood in near-poverty. He entered the Kaporsky Musketry regiment as a sub-ensign on 18 October 1766.

In 1769, during the Russo-Turkish War, 1768–1774, he participated in the blockade of Khotin and in other engagements. For his military valour he was promoted in September of the same year to ensign and in 1770 to second-Lieutenant. From 1770 to 1773 he served in the Nasheburgsky Musketry regiment under command of Alexander Suvorov and fought against the Polish Confederation.

In 1786 he became a Lieutenant Colonel and was appointed to the Moskowsky Grenadier regiment, serving there until 19 July 1789. He was then assigned to the Rostovsky Musketry regiment and fought in the Russo-Turkish War, 1787–1792. For his contributions during the battles at the Prut River and the taking of Focşani he was awarded the Order of St. Vladimir, 4th class, with ribbon. Later he distinguished himself at Izmail and was praised by Suvorov as one of those most contributed by his courage and discretion to gaining the complete victory over the enemy.
