"Come up to the top. There's ten minutes to go." The Staff Captain and the Sapper--their dispute settled--strolled amicably to the top of the hill behind the dug-out and produced their field-glasses. Away in front Essex Trench could be seen, and the men inside it, standing to. For them the period of suspense was nearly over--the curtain was just going up. "One minute." The Sapper snapped his watch to and focussed his glasses. "They're on." Suddenly from all around, as if touched by a spring, an ear-splitting din leaped into life. In the valley behind them it seemed as if hundreds of tongues of flame were darting and quivering, sprouting from what a moment before was barren ground. The acrid smell of cordite drifted over them, while without cessation there came the solemn boom--boom--boom of the heavier guns way back. Like the _motif_ of an opera, the field-guns and light howitzers cracked and snorted, permeating everything with one continuous blast of sound; while the sonorous roar and rumble of the giant pieces behind--slower, as befitted them--completed the mighty orchestra. Neither man could hear the other speak; but then, they were both watching too intently for that. Hardly had hell been let loose when a line of men arose from Essex Trench and walked steadily to their front. Just ahead of them great clouds of smoke rose belching from the ground: clouds into which they vanished at times, only to reappear a moment later. They were advancing behind a creeping barrage, and advancing with the steadiness of automatic machines. "Good lads! Good lads!" The Staff Captain's lips framed the words; his voice was inaudible. Every now and then a man pitched forward and lay still; or muttered a curse as he felt the sting of something in his arm. A section on the left dropped suddenly, only to worm on again by ones and twos, trying to avoid the dreaded toc-toc--slow and menacing--of a German machine-gun. Then the bombers were there. Crouching back, a man would pull the pin out of his bomb, run forward, and hurl it into the trench where the Germans were huddled in groups. And away behind the South Loamshires, on the shell-pocked ground that now boiled and heaved like some monstrous sulphur spring, with thick black and yellow fumes drifting slowly across it, there lay the first fruits of the harvest: a few of the gaps in the evening's roll-call. On the flank a machine-gun was going, taking them in enfilade. In front, Germans--numbers of Germans--glared snarling at them out of the trench, or whimpered in a corner with arms upraised, as was the nature of the beasts. A non-commissioned officer picked up a bomb and hurled it at the advancing platoon sergeant; only to cry "_Kamerad_" when it failed to explode. . . .
