Friedrich Adolf Graf von Kalckreuth (22 February 1737 – 10 June 1818) was aPrussianGeneralfeldmarschall.[1][2][3]
Kalkreuth was born inSotterhausen nearSangerhausen. He entered the regiment of Gardes du Corps in 1752, and in 1758 was adjutant oraide de camp toFrederick the Great's brother,Prince Henry, with whom he served throughout the later stages of theSeven Years' War. He won special distinction at thebattle of Freiberg (29 September 1762), for which Frederick promoted him major.[2]
Personal differences with Prince Henry severed their connection in 1766, and for many years Kalckreuth lived in comparative retirement. He participated in theWar of the Bavarian Succession as a colonel, and on the accession ofFrederick William II was restored to favour. He greatly distinguished himself as a major-general in the invasion of theNetherlands in 1787, and by 1792 had become count and lieutenant-general. Under theDuke of Brunswick, he took a conspicuous part in the campaign ofValmy in 1792, thesiege of Mainz in 1793, and theBattle of Kaiserslautern in 1794.[2]
Kalckreuth was defeated in the 1806Battle of Auerstedt. In 1807 he defendedDanzig for 78 days against the French underMarshal Lefebvre, with far greater skill and energy than he had shown in the previous year. He was promoted to field marshal soon afterwards, and conducted many of thenegotiations at Tilsit. He died as governor of Berlin in 1818.[2]
TheDictées du Feldmaréchal Kalckreuth were published by his son (Paris, 1844).[2]
