, the wife of
Jan Sobieski. Kleist served in the Prussian military during the reigns of three kings:
Frederick I,
Frederick William I, and
Frederick the Great. He joined the Prussian military in the Alt-Anhalt Regiment in 1698 or 1699, and saw active service continuously from the
War of Spanish Succession, which began in 1701, until the
Peace of Utrecht in 1713: he served in campaigns in the Netherlands, France and the Italian states under the command of
Leopold I, Prince of Anhalt-Dessau, known as the Old Dessauer (
der alte Dessauer). Consequently, he learned the military craft under the leadership of one of the foremost infantry commanders of the age. He fought at the memorable
Battle of Blenheim in 1704 in the
wing commanded by
Prince Eugene of Savoy. During the 1704 campaign, he also saw action under the leadership of the legendary
Türken-Louis. After the victories in southern Germany, his regiment went to northern Italy, where it participated in the fighting of
Cassano in 1705. He also helped to break the siege at
Turin in 1706, as part of the relief column that attacked the French army. Subsequently, he served in the
Great Northern War (1705–1721), and participated in the lengthy
Siege of Stralsund (1711–15). He acquired the patent as Chief (
Inhaber) of his regiment in 1718, which he held until retirement in 1723. During the
War of Austrian Succession, in 1741 as a lieutenant general he commanded the city
Kolberg. As a participant in the
Battle of Mollwitz, his infantry regiment not only held its line despite the flight of the Prussian cavalry, but subsequently attacked the Austrian line with such ferocity that he and his soldiers received special mention in
Kurt Christoph Graf von Schwerin's report. He was wounded in the fighting. The regiment's actions here reflected the iron training imposed by the prince of Anhalt Dessau on his subordinates, and their subsequent training of their own regiments. In addition, the Prussian infantry benefited not only from the discipline of drill but also the latest in military technology; unlike their Austrian counterparts, they had iron ramrods which allowed them to fire faster and more accurately. After the battle, he was made a
Knight of the Order of the Black Eagle on 15 April 1741, and later awarded the
Order Pour le Mérite. During the
Silesian Wars, in 1744 he acquired as
war booty the
gold-plated carriage originally belonging to
Jan Sobieski; Kleist gave the carriage to his local church. In 1745 Kleist was promoted to
General of Infantry and two years later, in 1747, to
field marshal, at the conclusion of a grand troop revue. He was promoted at the same time as Count
Friedrich Ludwig, Graf zu Dohna-Carwinden, von
Kalckstein (Frederick's educator and lifelong Councillor),
Joachim Christof von Jeetze and
Dietrich of Anhalt-Dessau. He became ill in 1749; von Kleist died on 22 August, at age of 73. ==Descendants==
