Gebhard Leberecht von Blcher, Frst von Wahlstatt , Graf , later elevated to Frst von Wahlstatt, was a Prussian Generalfeldmarschall . He earned his greatest recognition after leading his army against Napoleon I at the Battle of the Nations at Leipzig in 1813 and the Battle of Waterloo in 1815.
Blcher was born in Rostock, the son of a retired army captain. His military career began in 1758 as a hussar in the Swedish Army. He was captured by the Prussians in 1760 during the Pomeranian Campaign and thereafter joined the Prussian Army, serving as a hussar officer for Prussia during the remainder of the Seven Years War. In 1773, Blcher was forced to resign by Frederick the Great for insubordination. He worked as a farmer until the death of Frederick in 1786, when Blcher was reinstated and promoted to colonel. For his success in the French Revolutionary Wars, Blcher became a major general in 1794. He became a lieutenant general in 1801 and commanded the cavalry corps during the Napoleonic Wars in 1806.
