L. Oppenheim, International Law. A Treatise. Volume 2…
“ In contradistinction to hostile acts of soldiers by which the latter do not lose their privilege of being treated as members of armed forces who have done no wrong, war crimes are such hostile or other acts of soldiers or other individuals as may be punished by the enemy on capture of the offenders. It must, however, be emphasised that the term war crime is used, not in the moral sense of the term crime, but only in a technical legal sense, on account of the fact that perpetrators of these acts may be punished by the enemy. ”
