Re: Military/International Law in the Nap. Period
True but I think the point is that there were "laws of war" generally accepted by "civilized" nations in the Napoleonic period. They were certainly followed by the USA and Britain, often being quoted by the armies of both nations.
Unfortunately, they do not seem to have been ascribed to by Napoleonic France and thus we have the atrocity at Porto de Mos in early 1811 which cannot, in any sense, be justified.
