Beneath the sombre arches our adventurers go to and fro, exploring the ant-hill. All at once, having entered an unknown region, they discover a narrow staircase. They mount it. It leads to a revolving cupola. What luck! Through the peep-hole in the armoured wall it is possible for them to examine the whole of our northern horizon, right up to the wood. Upon the ploughs, the meadows, and the clover fields, the heavy projectiles from the 21-centimetre guns are falling incessantly. The earth shakes under their impact. Plumes of white smoke, like those emitted by burning straw, rise from the soil. Sometimes, in the clear atmosphere, they can distinguish the actual flight of the projectiles. But the imaginary columns of the assault are drawing nearer. The fire of percussion shells ceases; crackling shrapnel shells take their place. They pass from twenty to fifty yards above the glacis, great balls of dense smoke, from which are emitted in all directions smaller balls, a rain of satellites, which fly to pieces in their turn with the rattling noise of bullets. Our two red cross men are absorbed in this scene, which lies almost at their feet, when the German quartermaster comes in. Red with wrath, swearing like a cabdriver, he seizes them by the arm, hurls them down the iron stairway, and installs himself in their place. Crestfallen, but at bottom thoroughly well pleased at having enjoyed the sight, they return to the consulting-room to rejoin Badoy and his home-sickness. This little exploit filled the whole fort with glee. * * * * * From the look-out this morning, or let us say from your acacias, the country was exquisitely beautiful. The position of the valleys was indicated by diaphanous bands of blue vapour. They rose softly as far as the border of the pines and vanished there. Birds flew through the silent air, shining in the sunlight. I heard the ploughmen crying “_hue_” to their horses. Beyond the oak coppice which adjoins the glacis on the Wegstetten side, a great herd of oxen was grazing. All at once a company of Bavarian soldiers appeared upon the military road from behind the eastern redoubt. The men, recruits of the 1914 class, clad in blue tunic, and drill trousers tucked into their boots, bore no arms. They sang loudly as they marched, scanning the rhythm: Lieb’ Vaterland, magst ruhig sein, Fest steht und treu die Wacht am Rhein![18] Half way up the incline, between the forest and the fort, they halted. The captain, without dismounting, made them a speech. From a distance it sounded like barking. He stressed his syllables so vigorously that fragments reached my ears notwithstanding the distance. The word _Heimat_, home, came again and again, like a refrain. Then they intoned the national anthem: Heil dir im Siegerkranz, Herrscher des Vaterlands![19]
