World War I casualties
The total number of military and civilian casualties in World War I were about 40 million: estimates range from 15 to 19 million deaths and about 23 million wounded military personnel, ranking it among the deadliest conflicts in human history.

Of the 200,000 or so men court-martialed during the First World War, 20,000 were found guilty of offences carrying the death penalty. Of those, 3000 actually received it, and of those sentences, 346 were carried out. The others were given lesser sentences, or had death sentences commuted to a lesser punishment, e.g. hard labour, field punishment or a suspended sentence (91 of the men executed were under a suspended sentence: 41 of those executed were previously subject to commuted death sentences, and one had a death sentence commuted twice before). Of the 346 men executed, 309 were pardoned, while the remaining 37 were those executed for murder, who would have been executed under civilian law.
