At first these placards were signed by the burgomaster, with the military commandant's indorsement, and sometimes by both those functionaries; but on the second day there appeared one signed by the commandant only; and this one, for special emphasis, was bounded by wide borders printed in bright red. It stated, with cruel brevity, that the burgomaster, the senator for the district and the leading magistrate had been taken into custody as hostages for the good conduct of their constituents; and that if a civilian made any attack against the Germans he would forfeit his own life and endanger the lives of the three prisoners. Thus, inch by inch, the conquerors, sensing a growing spirit of revolt among the conquered--a spirit as yet nowise visible on the surface--took typically German steps to hold the rebellious people of Louvain in hobbles. It was when we reached the Y-shaped square in the middle of things, with the splendid old Gothic town hall rising on one side of it and the famous Church of Saint Pierre at the bottom of the gore, that we first beheld at close hand the army of the War Lord. Alongside the Belgian Lion we had thought it best to keep our distance from the troops as they passed obliquely across our line of vision. Here we might press as closely as we pleased to the column. The magnificent precision with which the whole machinery moved was astounding--I started to say appalling. Three streets converging into the place were glutted with men, extending from curb to curb; and for an outlet there was but one somewhat wider street, which twisted its course under the gray walls of the church. Yet somehow the various lines melted together and went thumping off out of sight like streams running down a funnel and out at the spout. Never, so far as we could tell, was there any congestion, any hitch, any suggestion of confusion. Frequently there would come from a sideway a group of officers on horseback, or a whole string of commandeered touring cars bearing monocled, haughty staff officers in the tonneaus, with guards riding beside the chauffeurs and small slick trunks strapped on behind. A whistle would sound shrilly then; and magically a gap would appear in the formation. Into this gap the horsemen or the imperious automobiles would slip, and away the column would go again without having been disturbed or impeded noticeably. No stage manager ever handled his supers better; and here, be it remembered, there were uncountable thousands of supers, and for a stage the twisting, medieval convolutions of a strange city. Now for a space of minutes it would be infantry that passed, at the swinging lunge of German foot soldiers on a forced march. Now it would be cavalry, with accouterments jingling and horses scrouging in the close-packed ranks; else a battery of the viperish looking little rapid-fire guns, or a battery of heavier cannon, with cloth fittings over their ugly snouts, like muzzled dogs whose bark is bad and whose bite is worse.
