The Battle of Wavre was the last battle of the Napoleonic Wars. It took place on June 18 and 19, 1815, between Prussian and French forces. Although the Prussians, outnumbered nearly two to one, were driven back, the Battle of Wavre prevented several French corps from participating in the Battle of Waterloo on June 18, 1815, thus contributing to the final downfall of Napoleon. Although deposed following this battle, Napoleon remained at large for a time in France. Eventually, he was exiled to Saint Helena where he died in 1821.
