In one of these drawings Mr. Bone gives a rousing glimpse of trench life at a moment of action. These are its moments of transfiguration, when all the glow of courage, that has been banked down and husbanded through months of waiting and guarding, bursts, at a word of command, into flame. The rest of trench life is work, contrivance and observation. It has been called monotonous. But, for any man who has not lost the heart of a boy, it has the relish of an endlessly changeful outdoor adventure, a game with the earth and the weather, as well as with the more official enemy.

No two points in an Allied front trench are wholly alike. Certain general patterns there are, but no facsimiles. Each traverse or bay has a look of its own; it is personal and expresses, as Robinson Crusoe’s stockade might have done, the nature of some man or men making shift, each after his kind, to put up what they could, in the shortest time, between their bodies and danger. A German firing trench is less various. In it you seem to see the minds of a few large and able contractors; in ours the minds of thousands of good campers-out. To put it in another way, the German trench has, in some measure, the quality of a long street built, well enough, to a single design; ours possesses the charm of a strip of coast or a long country lane, where nature or man has made every indentation and turn a surprise, and each farmer has made gates and hedges to his own mind.

The line goes through wonderful places and charges them with singular thrills of romance. It has made windmills famous as forts, and brought herons into the suburbs of cities. In one place it runs across water and land so intermixed that the sentries of both armies are upon little islands crowned with breast-works like grouse butts; you see them, when the winter evening falls, standing immobile, waist-deep in mist, each man about forty yards from his enemy. Men have stood there, turn by turn, for two years and a half, moving softly and whispering as if in a church, till the shyest of wildfowl have learnt to treat the surrounding marsh as their own, and the only sound is of wild duck and snipe astir between the muzzles of two nations’ loaded rifles, snipe safe among the snipers. At more than one place the two front lines converge until each sentry knows that he is within a gentle bomb’s throw of the enemy. Out of the firing trench, at one of these places, you walk on tiptoe along a short sap that halves this short distance, and from its end you look up at a small heap of rubble—a couple of cart-loads—and know that some German is cautiously listening, like you, on its further side.

Those are the cramped and contorted parts of the front. A few miles away it will straighten and loose itself out; you see it run free, in great, easy curves, up the slopes of wide moorlands, the two front lines drawn apart almost three hundred yards. Each is a double band of colour; the white ribbon of its dug chalk and the broader rust-brown ribbon of its tangled wire stand out clear against the shabby velveteen grey of the heath. Here there is less of thrill and more of ease in trench life; by day the sentries peer, hour by hour, into the baffling mist that is woven across their sight by our own and the enemy’s wire; it is like trying to see through low and leafless, but thick, undergrowth. By night the wire makes, to the sentry’s eye, a middle stratum of opaque dark grey, between the full blackness of the earth below it and the more penetrable obscurity of the night air above. But the darkness is never trusted for long. All night each army is sending up rocket-like lights to burst and hang like arc lamps in the air over the firing trench of the other. From a commanding point you can see, at any moment of any night, scores of these ascending rockets, each like a line drawn on the dark with a pencil of flame, arching over to intersect each other near the zenith of their flight, incessantly tracing and re-tracing the lines of a Gothic nave over all No Man’s Land, from the Alps to the sea. All night, too, there is a kind of pulse of light in the sky, along the whole front, from the flash of guns. From the trenches the flash itself can seldom be seen, but the sky winks and winks from moment to moment with the spread and contraction of a trembling radiance like summer lightning.

At most parts of the line a man in the front trench is cut off from landscape. To look at a tree behind the enemy’s lines may be to give a mark to a sniper hidden in its boughs. By day you see the upper half of the dome of the sky, and, through loopholes, a few yards of rough earth or chalk, then the nebulous wire and, through its thin places, perhaps a few uniforms, blue, grey or brown, lying beyond, among the coarse grass and weeds. At night you see all the stars well, and on moonlight nights, if you walk the trench softly, you can watch strange friezes sharply silhouetted on the sky line of the parapet, the wars and loves of capering rats, “flouting the ivory moon.” Whole choirs of larks may be heard: neither cannon nor small arms seem to alarm them; and most of the ground has its own hawk to quarter it daily.

To men put on this short allowance of natural sights and sounds it is an extraordinary pleasure to find in the rear of their trench a clean rivulet, such as often occurs in chalk land, where the surface water filters rapidly in and comes out at the bases of slopes like so many crystal springs. But the greatest of all trench delights is the re-discovery, every year, of the sun. Some day in March it is suddenly found to have a miraculous warmth, and everybody off duty comes out like the bees and stands about in the trench, sunning his head and shoulders in the tepid rays and adoring—quite inarticulately—and feeling that all’s well with the world. A winter in trenches revives, in us children of civilisation, a pre-Promethean rapture of love for the sun; and the dark nights, in which not a match must be struck, makes us, at any rate, think more highly than ever we did of the moon, which halves the strain of the soldier on guard, and of the stars which guide him back overland to his billet, at a relief, to sleep in Elysium. So, for a man who has all his senses alive and unjaded, the hard and bare life has its compensations. It makes him do without many things; but it also quickens delight in the things which are at the base of all the rest, and without which there could not have been the incomparable adventure and spectacle of life on the earth.
