From 1805 to 1807, he served in the Napoleonic wars, and was present at the battles of Pułtusk and Friedland. From 1809 to 1811 he participated in the Russo-Turkish War. He commanded the composite grenadiers division in Prince Petr Bagration's Second Western Army during Napoleon's invasion of Russia in 1812. At the battle of Borodino, his division was in the front line and was attacked by three French divisions under Marshal Davout. Of the 4,000 men in his division, only 300 survived the battle. Vorontsov was wounded but recovered to rejoin the army in 1813. He commanded a new grenadiers division and fought at the battle of Dennewitz and the battle of Leipzig. He was the commander of the corps of occupation in France from 1815 to 1818. On 7 May 1823 he was appointed governor-general of New Russia, as the southern provinces of the empire were then called, and namestnik of Bessarabia. In the year of the start of the Russo-Turkish War of 1828–1829, Vorontsov succeeded the wounded Menshikov as commander of the forces besieging Varna, which he captured on 28 September 1828. It was through his energetic efforts that the plague, which had broken out in Turkey, did not penetrate into Russia. His Polish wife, née Countess Branicka, had a liaison with Alexander Pushkin during her stay in Odessa, which resulted in some of the finest poems in the Russian language. In 1844, Vorontsov was appointed commander-in-chief and viceroy of the Caucasus. For military details see Murid War. At the battle of Dargo (1845), he was nearly defeated and barely fought his way out of the Chechen forest. By 1848 he had captured two-thirds of Dagestan, and the situation of the Russians
