August von Gneisenau in the context of "Battle of Ligny"

The Battle of Ligny, in which French troops of the Armée du Nord under the command of Napoleon I defeated part of a Prussian army under Field Marshal Blücher, was fought on 16 June 1815 near Ligny in what is now Belgium. The result was a tactical victory for the French, but the bulk of the Prussian army survived the battle in good order, was reinforced by Prussian troops who had not fought at Ligny, and played a role two days later at the Battle of Waterloo. Ligny was the last victory in Napoleon's military career. In the culminating moment of this battle Blücher was wounded and carried off the battlefield, and was replaced by his chief of staff, Lieutenant General Gneisenau.
