Ludwig Adolph Peter, Prince Wittgenstein (Pyotr Khristianovich Vitgenshtein) (German: Ludwig Adolph Peter Fürst zu Sayn-Wittgenstein Russian: Пётр Христиа́нович Ви́тгенштейн) (17 January (6 January) 1769 in Pereiaslav – 11 June 1843 in Lemberg, Austrian Empire) was a Russian Field Marshal distinguished for his services in the Napoleonic wars.
He was promoted to Major in 1793 of the Ukrainian light cavalry regiment. He fought with the unit in the Kościuszko Uprising. Promoted Colonel in 1798, and promoted to major general 1799, in 1800 he took command of the Mariupolski Hussars Regiment.
In the war of 1812 he commanded the right wing army of the Russian Army, which he commanded in the First and Second battle of Polotsk. It was the battle that decided fate of Saint-Petersburg, and earned him the title of "Saviour of Saint- Petersburg". Alexander I awarded him the Order of St. George. He tried to combine with Pavel Chichagov, at the Battle of Berezina, and later combined with the Prussian army corps under Ludwig Yorck von Wartenburg.
In the campaign of 1813 in January, he took over the command of the Russian army after Kutuzov's death, and commanded the Russian army at Lützen and Bautzen. But after the defeats of the Spring campaign, he laid down this command and led an army corps during the Battle of Dresden and Battle of Leipzig.
In 1823 he was promoted Field Marshal, and in 1828 he was appointed to command the Russian army in the war against Turkey. But ill health soon obliged him to retire. In 1834 the King of Prussia gave him the title of Fürst (Prince) zu Sayn-Wittgenstein.
His parents were Count Christian Louis Casimir of Sayn-Wittgenstein-Ludwigsburg and his first wife Countess Amalie Ludowika Finck von Finckenstein.
