What of the Waterloo combatants? The British (23,000 men) together with 44,000 allied Germans, Belgians, Dutch and Prussians (and their 160 guns) fought against 74,000 members of the French Grande Armée (and their 250 guns).
Approximately 141,000 men fought on the Waterloo battlefield that day. (Some accounts put the numbers even higher.)
The British, Belgians, Dutch and Germans sustained 15,000 casualties - or approximately one out of four who fought. The Prussians (under the command of von Blücher) lost 7,000 men. French losses were estimated at 25,000 dead and wounded with 8,000 prisoners taken and 220 guns lost.
Every year, while he lived, the Duke of Wellington held a “Waterloo” banquet for his officers. After he died, the banquet continued and is still held to this day.
