For those three days we stayed on unwillingly in Louvain we were not once out of sight of German soldiers, nor by day or night out of sound of their threshing feet and their rumbling wheels. We never looked; this way or that but we saw their gray masses blocking up the distances. We never entered shop or house but we found Germans already there. We never sought to turn off the main-traveled streets into a byway but our path was barred by a guard seeking to know our business. And always, as we noted, for this duty those in command had chosen soldiers who knew a smattering of French, in order that the sentries might be able to speak with the citizens. If we passed along a sidewalk the chances were that it would be lined thick with soldiers lying against the walls resting, or sitting on the curbs, with their shoes off, easing their feet. If we looked into the sky our prospects for seeing a monoplane flying about were most excellent. If we entered a square it was bound to be jammed with horses and packed baggage trains and supply wagons. The atmosphere was laden with the ropy scents of the boiling stews and with the heavier smells of the soldiers' unwashed bodies and their sweating horses. Finally, to their credit be it said, we personally did not see one German, whether officer or private, who mistreated any citizen, or was offensively rude to any citizen, or who refused to pay a fair reckoning for what he bought, or who was conspicuously drunk. The postcard venders of Louvain must have grown fat with wealth; for, next to bottled beer and butter and cheap cigars, every common soldier craved postcards above all other commodities. We grew tired after a while of seeing Germans; it seemed to us that every vista always had been choked with unshaved, blond, blocky, short- haired men in rawhide boots and ill-fitting gray tunics; and that every vista always would be. It took a new kind of gun, or an automobile with a steel prow for charging through barbed-wire entanglements, or a group of bedraggled Belgian prisoners slouching by under convoy, to make us give the spectacle more than a passing glance. There was something hypnotic, something tremendously wearisome to the mind in those thick lines flowing sluggishly along in streams like molten lead; in the hedges of gun barrels all slanting at the same angle; in the same types of faces repeated and repeated countlessly; in the legs which scissored by in such faultless unison and at each clip of each pair of living shears cut off just so much of the road--never any more and never any less, but always just exactly so much.
