But the Forward Officer paid little heed to these things. For one moment his gaze was riveted horror-stricken on the scene of the fight; the next he was on his feet, heedless of the singing bullets, heedless of the roar and crash of another shell that hit the ground and flung a cart-load of earth and mud whizzing and thumping about him, heedless of everything except the need to get quickly to the telephone.
'Tell the Battery, Germans advancing—heavy attack on our front!' he panted to the telephonist, jumped across to his corner, and heaved himself up into place. The dust had cleared now, so that he could see. And what he could see made him catch his breath. An almost solid line of Germans were clear of their trenches and pushing rapidly across the open on the weak centre. And the Battery's shells were falling behind the German line and still on their trenches. Swiftly the Forward Officer began to reel off his corrections of angles and range, and as the telephonist passed them on gun after gun began to pitch its shells on the advancing line.
The British rifles were busy too, and their fire rose in one continuous roar. But the fire was weakest from the thin centre line, the spot where the attack was heaviest. The guns were in full play again, and the shells were blasting quick gaps out of the advancing line. But the line came on. The rifles beat upon it, and a machine-gun on the less heavily pressed left turned and mowed the Germans down in swathes. Still the line came on stubbornly. It was broken and ragged now, and advanced slowly, because the front ranks were constantly melting away under the British fire. The Forward Officer watched with straining eyes glued to his glasses. A shell 'whooped' past close over his head, and burst just beyond him. He neither turned his head nor moved his glasses. One, two, three, four burst short, and splinters and bullets sang past him; two more burst overhead, and the shrapnel clashed and rattled amongst the stone and brick of the ruins. Without moving, the Forward Officer began to call a fresh string of orders. The rush of his shells ceased for a moment while the gunners adjusted the new angles and ranges. 'Number One fired. Two fired. Three, Four, Five, Six fired, sir,' called the telephonist, and as he spoke there came the shrieks of the shells, and the white puffs of the bursts low down and between the prone British line and the advancing Germans.
'Number Three, one-oh minutes more left!' shouted the Forward Officer.
'Number Five, add twenty-five—repeat.'
Again came the running bursts and puffing white smoke, and satisfied this time with their line, position, and distance, the Forward Officer shouted for 'Gun-fire,' jumped down and across to the telephonist's shelter-pit.
'I'm putting a belt of fire just ahead of our line,' he shouted, curving his fingers about his lips and the mouthpiece in an attempt to shut out the uproar about them. 'If they can come through it we're done—infantry can't hold 'em. Give me every round you can, and as fast as you can, please.' He ran back to his place. A cataract of shells poured their shrapnel down along a line of which the nearest edge was a bare twenty yards from the British front. The Forward Officer fixed his eyes on the string of white smoke-puffs with their centre of winking flame that burst and burst and burst unceasingly. If one showed out of its proper place he shouted to the telephonist and named the delinquent gun, and asked for the lay and fuse-setting to be checked.
The advancing Germans reached at last the strip of ground where his shrapnel hailed and lashed, reached the strip and pushed into it—but not past it. Up to the shrapnel zone the advance could press; through, it could not. Under the shrapnel nothing could live. It swept the ground in driving gust on gust, swept and besomed it bare of life. Here and there, in ones and twos and little knots and groups, the Germans strove desperately to push on. They came as far as that deadly fire belt; and in ones and twos and little knots and groups they stayed there and died. Supports hurried up and hurled themselves in, and a spasm of fresh strength and fury lifted the line and heaved it forward. So far the fire of its fury brought it; and there the hosing shrapnel met it, swept down and washed it away, and beat it out to the last spark and the last man.
But from the German trenches another assault was forming, from the German batteries another squall of shell-fire smote the British line; and to his horror, the Forward Officer saw his own shells coming slower and slower, the smoke-bursts growing irregular and slower again. He leaped down and rushed to the telephone.
Back in the Battery the telephone wires ran into a dug-out that was the brain-centre of the guns, and from here the Forward Officer's directions emerged and were translated to the gunners through the Battery Commander and the Battery Sergeant-Major's megaphone.
All the morning the gunners followed those orders blindly, sluing the hot gun-muzzles a fraction this way or that, making minute adjustments on sights and range drums and shell fuses. They could see no glimpse of the fight, but, more or less accurately, they could follow its varying fortunes and trace its movements by the orders that came through to them. When they had to send their shells further back, the enemy obviously were being pressed back; when the fire had to be brought closer the enemy were closer. An urgent call for rapid fire with an increasing range meant our infantry attacking; with a lessening range, their being attacked.
