At dawn the next morning, the tanks were already lined up, sullen and menacing in the cold half-light. The men shivered in the biting air. One by one the crews entered the machines, and one by one the little steel doors closed behind them. The engines throbbed, and they moved off sluggishly.

Darwin and Talbot, with their orderlies, waited impatiently. The moments just before an attack are always the hardest. A few batteries were keeping up a desultory fire. They glanced at their watches.

"Only a minute to go," said Darwin. "I bet the show's put off or something. Isn't this snow damnably cold, though!"

Suddenly a sixty-pounder in our rear crashed out. Then from all sides a deafening roar burst forth and the barrage began. As we became accustomed to the intensity and ear-splittingness of the sound, the bark of the eighteen-pounders could be faintly distinguished above the dull roar of the eight-inches. The sky-line was lit up with thousands of flashes, large and small, each one showing, for a second, trenches or trees or houses, and during this tornado we knew that the "Willies" must have started forward on their errand.

As the barrage lifted and the noise died down a little, the first streaks of light began to show in the sky, although we could distinguish nothing. No sign of the infantry or of the tanks could be seen. But the ominous sound of machine guns and heavy rifle-fire told us that the Boche was prepared.

We could stand this inactivity no longer. We trudged forward through the snow, taking the broad bands left by the tracks of the busses as our guide, the officers leading the way and the orderlies behind in single file.

"The blighter's starting, himself, now," said Talbot, as a four-two landed a hundred yards away, and pieces of earth came showering down on our heads. Then another and another fell, each closer than the one before, and instinctively we quickened our steps, for it is difficult to walk slowly through shell-fire.

The embankment loomed before us, and big splotches of black and yellow leaped from its surface. The deafening crashes gave us that peculiar feeling in the stomach which danger alone can produce. We scrambled up the crumbling, slaggy sides, and found when we reached the top that the sound of the machine guns had died away, excepting on the extreme left in front of B——, where the ordinary tap of ones and twos had developed into a sharp crackle of tens and twenties. By listening carefully one could feel, rather than hear, the more intermittent bursts from the rifles.

"There's one, sir," shouted one of the orderlies.

"Where?"
