Hello,
The first War trials were held after the US Civil War.
Henry Wirtz the Swiss born commandant of the Confederate Prison Camp : Andersonville was the only Criminal prosecuted. They were a small number of trials held in Leipzig 1921 resulting from the first World War. War Trials gained in importance after World War Two, the Nuremburg Trials were seen to try the surviving Culprits and are held in The Hague currently. Do you think Napoleon should have been tried as a War Criminal instead of being exiled twice?
Regards
Adrian.
