Presently an order came to the battery. It opened fire again, this time deliberately, without haste, at 2500 yards and in a slightly different direction. Again the subaltern appealed to the captain for information. "Infantry advancing. We've only got a screen there. Sixth Corps coming into action on our right. We're filling the gap between it and the Second Corps. Enemy are trying to break through." "Oh," said the subaltern, "we're in for a hot time, I suppose." He said it carelessly, without any idea of what was coming. "We most certainly are," said the captain. The emphasis of the reply startled the subaltern, made him feel uneasy. He devoted himself to his guns in an effort to banish the anxiety which threatened him. The gun-squads were working with unhurried precision. A man kneeling behind the wagon drew out the long projectile, set the fuze, passed the shell to his fellow at the gun, the breech was closed, the lever pulled, and the gun spoke with an exactly equal interval between rounds. They might have been feeding a machine in a factory, so regular, so unemotional was the operation. Behind the wagon the ground was littered with the canvas cartridge clips. Behind the gun the flung-back brass cartridge cases mounted to a heap. In front the air was blurry with gases. Away to the right a new series of reports broke out. More batteries had evidently come into action. Coalescing all individual sounds the general clamour of the battle swelled in surges of hideous noise from one deep-toned, continuous roar. The subaltern became habituated to it, scarcely noticed it. Happening to look round he saw a howitzer battery coming into the field. A few minutes later the regular sequence of its detonations told him it had got to work. It was evident that troops were being hurried up to meet the threatened attack. Along the hill-side to the right a line of infantry was strung out, advancing towards the wood. Another followed it. When he turned again he saw more infantry entering the field and deploying. He got a glimpse of the road filled with brown caps that just showed above the hedges. Almost immediately the battery ceased fire. Only the periodic discharges of the howitzers continued. The battery commander was kneeling over a map spread upon the ground. Up by the little wood a heliograph was flashing rapidly. A little further on a couple of men were flag-wagging with vigour. Some crisis was approaching. Behind him the infantry commenced to advance. On his left front a couple of men spurred horses up the flank of the bare hill-side.
