Not until then did it occur to any one of us that we had not spoken to the men in charge of the wagon, or they to us. There was one detached house, not badly battered, alongside the road at the lower edge of the field where the burial took place. It had a shield on its front wall bearing the Belgian arms and words to denote that it was a customs house. A glance at our map showed us that at this point the French boundary came up in a V-shaped point almost to the road. Had the gravediggers picked a spot fifty yards farther on for digging their trench, those two dead Frenchmen would have rested in the soil of their own country. The sun was almost down by now, and its slanting rays slid lengthwise through the elm-tree aisles along our route. Just as it disappeared we met a string of refugees--men, women and children--all afoot, all bearing pitiably small bundles. They limped along silently in a straggling procession. None of them was weeping; none of them apparently had been weeping. During the past ten days I had seen thousands of such refugees, and I had yet to hear one of them cry out or complain or protest. These who passed us now were like that. Their heavy peasant faces expressed dumb bewilderment--nothing else. They went on up the road into the gathering dusk as we went down, and almost at once the sound of their clunking tread died out behind us. Without knowing certainly, we nevertheless imagined they were the dwellers of Montignies St. Christophe going back to the sorry shells that had been their homes. An hour later we passed through the back lines of the German camp and entered the town of Beaumont, to find that the General Staff of a German army corps was quartered there for the night, and that the main force of the column, after sharp fighting, had already advanced well beyond the frontier. France was invaded. CHAPTER II TO WAR IN A TAXICAB In a taxicab we went to look for this war. There were four of us, not counting the chauffeur, who did not count. It was a regular taxicab, with a meter on it, and a little red metal flag which might be turned up or turned down, depending on whether the cab was engaged or at liberty; and he was a regular chauffeur. We, the passengers, wore straw hats and light suits, and carried no baggage. No one would ever have taken us for war correspondents out looking for war. So we went; and, just when we were least expecting it, we found that war. Perhaps it would be more exact to say it found us. We were four days getting back to Brussels, still wearing our straw hats, but without any taxicab. The fate of that taxicab is going to be one of the unsolved mysteries of the German invasion of Belgium.
