Wrangel was born in
Stettin (now
Szczecin,
Poland) in
Pomerania into the
Wrangel family. He was actually a relative uncle to the world-famous explorer
Ferdinand von Wrangel. He entered a
dragoon regiment in 1796 and became second lieutenant in 1798. He fought as a subaltern during the
Napoleonic Wars, distinguishing himself especially at
Heilsberg in 1807 and receiving the order
Pour le Mérite. In the reorganization of the army, Wrangel became first lieutenant and then captain; won distinction and promotion to lieutenant-colonel in the
War of Liberation in 1813; won the
Iron Cross at
Wachau, near
Leipzig; and became colonel in 1815. Wrangel commanded a
cavalry brigade in 1821, and two years later, he was promoted to major-general. He commanded the 13th Division, with headquarters at
Münster, in
Westphalia, in 1834 during riots caused by differences between the
Archbishop of Cologne and the Crown, and the determination and the resolution with which he treated the clerical party prevented serious trouble. He was promoted to lieutenant-general, received many honours from the court, enjoyed the confidence of the
Junkers and commanded at
Königsberg and then Stettin. ==First Schleswig War==
