I regained my trench sunk in melancholy thought. No longer did I see the forest about me, beautiful in its last and most splendid garb. Here is the trench, a narrow ditch between two vertical walls of earth. A few scattered men are fast asleep at the bottom of it. The night will see it peopled from end to end. And away beyond the edge of the wood there are more and still more trenches like this, one and all filled with soldiers. Further away, over the plain, are other trenches, but they are filled with soldiers who are not like ours. We dig, but over there, where the men in the spiked helmets teem, they too dig, and more and better than we do. I have watched them at work, these human moles. Along the Cuisy valley, I one day watched them through my glasses for hours, and saw them handling pick and shovel with a vigour that knew no pause or slackening. As soon as they can safely call a halt, the Boches instantly dig their holes and take refuge in them. If they advance, they entrench themselves, to ensure continued possession of the ground they have won. If they retreat, yet again they entrench in order the better to repulse the assaults hurled against them. And day by day I see, facing our lines, these entrenchments grow and extend, escalating hills, plunging into valleys, crossing plains; deep trenches with their parapets stark and clear against the sun, with their meshed miles of barbed wire rising high before the machine-gun emplacements. First we checked them, then we rolled them back. In the ensuing pause, both armies are now regaining their breath. Panting from their recent exertions, too weary yet once again to hurl themselves against the barrier we present and pass onwards over our bodies, they have set themselves down on the soil of France, which they still occupy. And that they may remain in greater security and comfort, they have set up their barriers against us. Ingeniously, methodically, they accumulate and multiply the obstacles. Nothing is left to chance; every yard of ground they hold will have its guard of rifles; behind each hilltop there will be big guns. There is no gap, no weak point. From Flanders to Alsace, from the North Sea to the frontiers of Switzerland, one immense, stupendous fort is being created, which we must shatter before we can pass.
