Hardu said:I don't know what army you are describing. Some factual information, please.
The behaviour of troops directly reflects the values of the society producing them. The 19th Century was an age of declining crime. Military discipline was harsh and troop control very strict. There was, as a consequence less maltreatment of the civilian population in war than at any other time in history.
Which is why Henri Dunant was concerned with the suffering of the military wounded only at Solferino.
As an example, if you exclude the Rusian Revolution and its aftermath, civilian casualties in the First World War were only 10% of military casualties. In the Second World War, civilian casualties outnumbered military.
But for many (most?) combatants the impact of the First World War on their demographics and population growth was significant. Other wars had a negligible impact on population.
