In countries they invaded in World War I “the Germans generally insisted on the right to requisition and to demand docility from a population under occupation. They were not alone in this, but they were virtually alone in positing an extreme version of the argument – the idea of Kriegsverrat. According to this view, the disruption of the war effort by civilians in occupied territory is as treasonous as disruption by one’s own nationals. The German occupation of Belgium was consistent with this proposition, and while as a whole certainly not as monstrous as Allied propaganda made it out to be, the occupation policy was nevertheless draconic. If babies were not systematically snatched from mothers’ arms and smashed against brick walls, if nuns were not deliberately sought out for sodomy, rape, and slaughter, if old people were not made to crawl on all fours before being riddled with bullets, considerable numbers of hostages were shot, including women and children and octogenarians. Louvaine was razed, together with its library, founded in 1426, with its 280,000 volumes at its priceless collection of in incunabula and medieval manuscripts. Schrechlichkeit, or frightfulness, was pronounced official policy in the occupied areas, initially in Belgium and then in France in Russia. The term furor teutonicus was used by Germans with pride.”
