It was a beautiful morning--soft and mildly warm and sunny, with just a slight haze hanging low to tone the growing light, and, incidentally, to delay the opening of fire from the guns. Anyone standing midway between the forward firing trenches might have looked in vain for living sign of the massed hordes waiting the word to be at each other's throats. Looking forward from behind the British lines, it could be seen that the trenches and parapets were packed with men; but no man showed head over parapet, and, seen from the enemy's side, the parapets presented blank, lifeless walls, the trenches gave no glimpse of life. All the bustle and movement of the night before was finished. At midnight every road and track leading to the forward trenches had been brimming with men, with regiments tramping slowly or squatting stolidly by the roadside, smoking much and talking little, had been crawling with transport, with ammunition carts, and ambulances and stretcher-parties, and sappers heavily laden with sandbags and rolls of barbed wire. The trenches--support, communication, and firing--had trickled with creeping rivulets of khaki caps and been a-bristle with bobbing rifle-barrels. Further back amongst the lines of guns the last loads of ammunition were rumbling up to the batteries, the last shells required to 'complete establishment'--and over-complete it--were being stowed in safe proximity to the guns. At midnight there were scores of thousands of men and animals busily at work with preparations for the slaughter-pen of the morrow. Before midnight came again the bustle would be renewed, and the circling ripples of activity would be spreading and widening from the central splash of the battle front till the last waves washed back to Berlin and London, brimming the hospitals and swirling through the munition factories. But now at daybreak the battle-field was steeped in brooding calm. Across the open space of the neutral ground a few trench periscopes peered anxiously for any sign of movement, and saw none; the batteries' 'forward observing officers,' tucked away in carefully chosen and hidden look-outs, fidgeted with wrist-watches and field-glasses, and passed back by telephone continual messages about the strength of the growing light and the lifting haze. An aeroplane droned high overhead, and an 'Archibald' (anti-aircraft gun) or two began to pattern the sky about it with a trail of fleecy white smoke-puffs. The 'plane sailed on and out of sight, the smoke-puffs and the wheezy barks of 'Archibald' receding after it. Another period of silence followed. It was broken by a faint report like the sound of a far-off door being slammed, and almost at the same instant there came to the ear the faint thin whistle of an approaching shell. The whistle rose to a rush and a roar that cut off abruptly in a thunderous bang. The shell pitched harmlessly on the open ground between the forward and support trenches. Again came
