So we were retreating.  Then all our calculations and dreams were shattered.  All the fine plans we officers had sketched out together were folly.  We were wasting time when, bending over our maps, we foresaw a skilful advance on the heels of Belgium’s invaders, followed by a huge victory, dearly bought, perhaps, but one that would upset the German Colossus at a single blow.  The whole thing was an illusion.  And I thought what a fool I had been.  I thought of my regiment.  How much of it was there left?  How many of those good fellows were lying dead on foreign soil?  How many friends should I never see again?  For I imagined things to be worse than they really were.  I felt absolutely despondent.  What my mind conjured up was no longer a retreat in good order but a rout.

The train had begun to move again.  The sun had set, and over the horizon there was but a streak of pale yellow sky lighting up the country.  I sat down in the open doorway with my legs dangling outside, and as I breathed the first few whiffs of fresh air I felt somewhat relieved.  The calm around was such as to make one forget that we were at war.  Darkness came on by degrees.

Suddenly my heart began to beat faster, and I rose with a nervous movement.  Wattrelot too had started up from the straw he had been lying on.  We both exclaimed in one breath:  “Cannon!” It was a mere distant growl, hardly audible, and yet it was distinct enough to be a subdued accompaniment to the thousand noises a train makes as it goes along.  We could not distinguish the shots, but gradually the dull sound became louder and seemed to be wafted towards us by a gust of air.  Then it seemed to be further off again, and almost to die away, and again to get louder.  There is no other earthly sound like it.  A thunderstorm as it dies away is the only thing that could suggest the impression we felt.  It sends a kind of shiver all over the surface of the body.  Even our horses felt it.  Their three heads were raised uneasily, their eyes shone in the twilight, and they snorted noisily through their dilated nostrils.

Leaning out, I saw the heads of the Territorials thrust out of the windows.  They, too, had heard the mysterious and stirring music.  No one spoke or joked.  Their bodies, stretching out into space, seemed to be asking questions and imploring to know the truth.  We came nearer to the sounds of the guns and could now distinguish the shots following one another at short intervals.  The air seemed to be shaken, and we might have thought we were but a few paces off.

The train had pulled up sharply in the open country.  It was still light enough for us to make out the landscape—­meadows covered with long pale grass, bordered by willows and tall poplar trees gently swaying in the evening breeze.  In the background a thick wood shut in the view.  The railway line curved away to the right and was lost to view in the growing darkness.  Now that the train was motionless the impressive voice of the cannon could be heard more distinctly.  The long luminous trails of the search-lights passed over the sky at intervals.
