It is difficult to fathom the enormity of casualties sustained on Napoleonic battlefields when reading accounts of the various battles. For example, following are the total casualties for several of the more prominent battles:
| Battle | French Casualties | Enemy Casualties |
| Austerlitz |
|
|
| Borodino |
|
|
| Eylau |
|
|
| Jena-Auerstadt |
|
|
| Waterloo |

At this point I would like to state that I am a Vietnam Veteran (1967-68 and 1971) and that I have seen my share of action as a small arms infantryman, especially on 23 November 1967, the day before Thanksgiving Day, near Phan Thiet, in which my battalion, the 2nd Battalion, 7th Cavalry, First Cavalry Division (Airmobile), sustained more than 50% casualties and all of its helicopters, as well as many additional helicopters sent to assist us from division headquarters.
Now let me point out that all of the Napoleonic battles listed above began and ended on the same day, usually from sunrise to sunset. Waterloo was a 10-hour battle; therefore, there were an everage of 6,100 casualties per hour of the battle. This is tremendous. Except for a very few battles in World War I, no battle fought in the 20th Century can come close to matching the horror of the typical large Napoleonic battle.
I always knew that the casualties sustained on the Napoleonic battlefield were huge; however, I never realized the true impact until I began working on this project: I typed the hundreds of names of the casualties that the Anglo-Allied army sustained at Quatre-Bras on 16 June, during the army's retreat to Mont. St. Jean on 17 June, and lastly at Mont. St. Jean, which we commonly call Waterloo because the Duke of Wellington wanted the battle to have a proper English sounding name, on 18 June 1815. The following casualty lists are large; that for the 18th of June is huge. If you have a half-hour or so to read the casualty lists, I'm certain that you too will develop a new appreciation for the true horrors of warfare. There are several hundred names included in the lists--all officers. When reading the names, remember that they are just the officers and amount to only about 5% of the total casualties sustained by the Anglo-Allied army; the other 95% were the enlisted soldiers. Then consider the casualties sustained by the Prussians, which were considerably less, and those sustained by the French, which were almost double those of the Anglo-Allies (at Waterloo).
