Behind each of them was a mixed group of soldiers--Garde Civique, gendarmes and burgher volunteers. These latter mainly carried shotguns and wore floppy blue caps and long blue blouses, which buttoned down their backs with big horn buttons, like little girls' pinafores. There was, we learned, a touch of sentiment about the sudden appearance of those most unsoldierly looking vestments. In the revolution of 1830, when the men of Brussels fought the Hollanders all morning, stopped for dinner at midday and then fought again all afternoon, and by alternately fighting and eating wore out the enemy and won their national independence, they wore such caps and such back-buttoning blouses. And so all night long women in the hospitals had sat up cutting out and basting together the garments of glory for their menfolk. No one offered to turn us back, and only once or twice did a sentry insist on looking at our passes. In the light of fuller experiences I know now that when a city is about to fall into an enemy's hands the authorities relax their vigilance and freely permit noncombatants to depart therefrom, presumably on the assumption that the fewer individuals there are in the place when the conqueror does come the fewer the problems of caring for the resident population will be. But we did not know this mighty significant fact; and, suspecting nothing, the four innocents drove blithely on until the city lay behind us and the country lay before us, brooding in the bright sunlight and all empty and peaceful, except for thin scattering detachments of gayly clad Belgian infantrymen through which we passed. Once or twice tired, dirty stragglers, lying at the roadside, raised a cheer as they recognized the small American flag that fluttered from our taxi's door; and once we gave a lift to a Belgian bicycle courier, who had grown too leg-weary to pedal his machine another inch. He was the color of the dust through which he had ridden, and his face under its dirt mask was thin and drawn with fatigue; but his racial enthusiasm endured, and when we dropped him he insisted on shaking hands with all of us, and offering us a drink out of a very warm and very grimy bottle of something or other. All of a sudden, rounding a bend, we came on a little valley with one of the infrequent Belgian brooks bisecting it; and this whole valley was full of soldiers. There must have been ten thousand of them--cavalry, foot, artillery, baggage trains, and all. Quite near us was ranged a battery of small rapid-fire guns; and the big rawboned dogs that had hauled them there were lying under the wicked-looking little pieces. We had heard a lot about the dog-drawn guns of the Belgians, but these were the first of them we had seen.
