It was then just seven o'clock. Our guns had almost ceased fire. There were strange sinister silences over all the battlefield, broken only by single gun-shots or the high snarl of German shrapnel or the single thud of a German crump. It was almost dark. The blue went out of the little Souchez river. Lens and Avion were in gulfs of blackness. A long rolling thunderclap shook all the sky, and flashes of lightning zigzagged over the Vimy Ridge, whitening the edges of its upheaved earth. The sky opened, and a storm of rain swept down fiercely.
"Yes, the 'good old German God' is busy again," said my fellow-tenant of the shell-crater and of the pond that welled up in it. "Just our beastly luck!" It was ten minutes past seven, and we had heard that the battle was to begin at seven. Perhaps it had been postponed.
As the thought was uttered the battle began. It began with one great roar of guns. Not only behind us but far to our right and left. Flights of shells passed over our heads as though long-tailed comets of the spheres had broken loose from the divine order of things. In a wide sweep round Lens they burst with sharp flashes and lighted fires there. Outside the Cité du Moulin, at the western edge of Lens, a long chain of golden fountains rose as though little mines had been blown, and they were followed by a high bank of white impenetrable smoke. On the right of Avion another smoke-barrage was discharged, and above it there rose one of the strangest things I have seen in war. It was the figure of a woman, colossal, so that her head seemed to reach the heavens. It was not a fanciful idea, as when men watch the shapes of clouds and say, "How like Gladstone!" or "There is a camel!" or "A ship!" This woman figure of white solid smoke was as though carved out of rock, and she seemed to stare across the battlefield, and stayed there unchanged for several minutes. The guns continued their fury. Rockets went up out of Avion, and the German guns answered these signals. There was one wild tumult of artillery beating down the lines southward to Oppy, and beyond and above and through and into all this violence of sound there was the roll and rattle of thunder--heavy claps--and the rattle of the storm-drums. Lightning flashed above the flashes of our batteries, gave a livid outline to black trees and chimneys, and pierced the heart of all this darkness with long light swords. It was bad luck for our men, as I have heard since from messages which came back out of those smoke-banks through which no mortal eye could see. The men were drenched to the skin as soon as they started to attack. The rain beat into their faces and upon their steel hats. In a few minutes all the shelled ground across which they had to fight became as slippery as ice, so that many of them stumbled and fell. In Avion the enemy had already let loose floods to stop the way to Lens, and by the rain-storm they spread into big swamps. But the Canadians went ahead straight into the streets of Avion, leaving little searching-parties on their trail to make sure of the ruined houses, where machine-guns might be hidden.
