After having received home education, Ernest Stackelberg entered military service in 1832 as a feuerwerker (cannoneer) in Leib Guard horse artillery. In 1833, he was promoted to junker and then warrant officer a year later. After two years of service in horse artillery, Ernest Stackelberg was sent to the Caucasus, where he would take part in several military campaigns (e.g., the Kuban Campaign of 1836 under the command of General Alexei Velyaminov and the 1837 campaign against the Chechens). For his service, Ernest Stackelberg was promoted to the rank of podporuchik and then transferred to the office of War Minister Alexander Chernyshyov as adjutant. In 1840, he was promoted to the rank of poruchik and sent to Caucasus yet again to participate in military action. Ernest Stackelberg was first placed under the command of Lieutenant General Apollon Galafeyev and took part in the Battle of the Valerik River with the Chechens in Chekhinsky Forest. Later on, Ernest Stackelberg was transferred to the unit under the command of General Grigory Zass (commander of the right flank of the Caucasus front) and fought against the mountaineers from over the Kuban River. For his outstanding service, Ernest Stackelberg was promoted to the rank of staff captain and awarded with the Order of Saint Vladimir, 4th Class. Upon his return from the Caucasus in 1841, Stackelberg continued his service as adjutant and was then promoted to the rank of colonel in 1843. Three years later Ernest Stackelberg was dismissed from service on indefinite leave for health reasons. In 1848, however, he was called for active duty again and sent to the Russian diplomatic mission in Paris. His diplomatic service in France, however, turned out to be short-lived, for he was recalled to the War Ministry yet again. In 1852, Ernest Stackelberg was sent to the Russian diplomatic mission in Vienna. That same year, he was promoted to the rank of major general and then appointed to His Majesty’s retinue in 1853. In 1856, Ernest Stackelberg was entrusted with the post of envoy extraordinary and minister plenipotentiary in Kingdom of Sardinia and held this post for the next five years. In 1860, Stackelberg was promoted to the rank of His Majesty’s general adjutant. In 1861, he was appointed envoy extraordinary and minister plenipotentiary to Spain and then sent to Italy in the same capacity a year later. In 1863, Ernest Stackelberg was moved to Vienna as envoy extraordinary and minister plenipotentiary. Four years later, he was appointed ambassador extraordinary and plenipotentiary to Paris, where he would die on August 30, 1870.
