The decisive battle of its age, it concluded a war that had raged for 23 years, ended French attempts to dominate Europe, and destroyed Napoleon’s imperial power forever.

He decided to go on the offensive, hoping to win a quick victory that would tear apart the coalition of European armies formed against him. Two armies, the Prussians led by Field Marshal Gebhard von Blücher and an Anglo-Allied force under Field Marshal the Duke of Wellington, were gathering in the Netherlands. Together they outnumbered the French. Napoleon’s best chance of success was therefore to keep them apart and defeat each separately.
