History It is known as the site of the 1815 Battle of Ligny, where Napoleon achieved his last ever victory, defeating Blücher, while the forces of Wellington and Marshal Ney were engaging each other at the Battle of Quatre Bras. Two days later, the combined forces of both opponents met at the Battle of Waterloo. References Former municipalities of Namur (province) Battle of Ligny locations
