A sudden shot, off to the right front—a swift succession of loud reports—woke wild echoes from unseen cliffs. High up on the glacier, to the left of the Austrian position, flare after flare was flung into the sky, eerily illuminant, plucking strange rock-forms into grotesque relief. There was a fierce shout that rolled in repeated reverberation, a wild tumult of voices in a crisis of human lives, confused shots, isolated and in irregular volleys, the dull thudding explosions of bombs. The first company was attacking.

The two officers lying in the snow gazed with fixed intensity towards the distant fight whose tumult swelled louder and louder with every moment. The wild flares continued to soar into the night, but as yet no rocket—neither red nor green—had leaped up to tell them of its fortunes. The searchlight in front shot out again, swept quickly from side to side. It illumined only the apparently empty, tumbled desolation of the glacier. But it continued to blaze out into the night. Both officers cursed it under their breath. From the trenches they had left, far behind, rifle-shots rang out, the rapid hammering of a machine-gun. The reserve company was indulging in a little tricky target-practice at the searchlight. It was successful. The beam of light vanished.

At the same moment a little spark of trailing fire went rushing skywards from the tumult of the flank attack. It was watched with suspended breath—green or red? The rocket burst into an effulgence of uncanny green light. The cheer which came from under it was like a ghostly utterance of the cheer repressed on the lips of the men lying prone and motionless on the glacier. The colonel's forecast was sound.

But now the uproar on the flank increased to a wild intensity. Incessant were the sharp detonations of the rifles, the dull thuds of the bombs, mingling with a clamour of voices, shrieks and yells. No more flares went up from the point of conflict, but from all along the trench they soared into the air, symptomatic of the nervousness of the unseen defenders. Machine-guns began to rap out their streams of bullets in blind hazard across the glacier.

The staff-captain pressed himself close to the snow, overhead cracked the rapid bullets of the Austrian machine-guns. The wind that blew over the glacier, ruffling the loose surface snow on to his face, was intensely cold. He felt himself a heavy leaden thing, frozen stiff. Over to his right front the savage noises of the contest, weird and awe-inspiring on this summit of the world that seemed so uncannily near to the flashing stars, swelled hideously cacophonous. Livid bursts of flame flickered and were reflected redly on snow surfaces, on black jagged spires of rock. All along the trench the blindingly white flares leaped upward, another soaring as its predecessor circled down in a parabola that illumined the unearthly confusion of the glacier surface. He seemed a mortal for ever severed from his fellow-men, set down in a world that was primitive Arctic chaos, a paralysed spectator of a contest of fierce mountain spirits fighting over spectral issues, remote from the interests of humanity. A part of his mind harked back to the warm summer, the green fields, the somnolent little town of the valley he had left that morning, and it seemed that those things belonged to another existence. Yet all the time he gazed fixedly to the point whence the next rocket should shoot up. He awaited it as he would await the breaking of a spell.

At last! The trailing spark of fire shot upwards, burst into hanging globes of red light, the snow rosy beneath them. On the instant the company was erect, rushing forward. Leaping, soaring flares from the trench revealed them—white moving figures casting black shadows on the white glacier. Spurts of livid flame, loud quick detonations darted from the white ridge in front. "Avanti! Avanti! Italia! Italia!" shouted the commander. "Italia! Italia! Savoia!" came the fierce antistrophe from the rushing men flinging aside their alpenstocks, brandishing their bayoneted rifles.

They were fighting their way through the deep loose snow, the wreck of the wire entanglements. The staff-captain floundered in a white shell-crater pitilessly illumined by an overhanging flare. The loose ends of the barbed wire tore at his clothes, clutched round his legs like tentacles that would hold him for death to strike. In front the spurts of flame sprang from a wall of darkness above the white, high up. Near him was the company commander, extricating himself from the shell-hole, the last of the wire safely passed. He had a sense of tensely struggling figures all around him. He, too, got clear of the wire. He saw the company commander throw up his hands, roll sideways over the snow, still shouting "Avanti! Avanti! Italia!"

He passed him, took up the cry: "Avanti! Avanti! Italia! La più grande Italia!" leading the company that yelled behind him like a pack of mountain wolves. He topped the snow parapet, saw a fierce face glaring up at him in a strange light, a rifle-barrel levelled. His revolver seemed to go off of itself, a sharp autonomous detonation. The face opened a black mouth, sank out of vision.

He sprang into the trench, shouting like a madman. Behind him came the Italians, tumbling down in fierce onslaught. One of them struck him violently on the back as he slid down, knocked him face forward into the snow. As he went he heard a sudden heavy crash, saw a flare of lurid light. A bomb! He picked himself up, only half realising his escape, fired at once into a dark body that wrestled with a white-clad soldier. There was a confusion of blows, of shots, of ear-splitting detonations—shouts, cries, shrieks. At one moment he was in close contact with a panting man, warm breath upon his face, eyes flashing momentarily in the reflection of a rifle-shot, looking into his—the next the man was gone, there was space about him. The confusion cleared—there were bodies underfoot—white-clad men about him shouting unintelligibly. Further along the trench another flare went up.

The staff-captain turned to his right along the trench.
