3.30 A.M.: The telephone bell above my head was tinkling. It was the brigade-major's voice that spoke. "Will you put your batteries on some extra bursts of fire between 3.45 and 4.10—at places where the enemy, if they are going to attack, are likely to be forming up? Right!—that gives you a quarter of an hour to arrange with the batteries. Good-night!"

My marked map with registered targets for the various batteries was by the bedside, and I was able, without getting up, to carry out the brigade-major's instructions. One battery was slow in answering, and as time began to press I complained with some force, when the captain—his battery commander was away on a course—at last got on the telephone. Poor Dawson. He was very apologetic. I never spoke to him again. He was a dead man within nine hours.

I suppose I had been asleep again about twenty minutes when a rolling boom, the scream of approaching shells, and regular cracking bursts to right and left woke me up. Now and again one heard the swish and the "plop" of gas-shells. A hostile bombardment, without a doubt. I looked at my watch—4.33 A.M.

It was hours afterwards before I realised that this was the opening bombardment of perhaps the mightiest, most overpowering assault in military history. Had not the "Prepare for Attack" warning come in I should have been in pyjamas, and might possibly have lain in bed for two or three minutes, listening quietly and comfortably while estimating the extent and intensity of the barrage. But this occasion was different, and I was up and about a couple of minutes after waking. Opening my door, I encountered the not unpleasant smell of lachrymatory gas. The Infantry Battalion headquarters' staff were already moving out of the quarry to their forward station. By 4.40 A.M. our colonel had talked over the telephone with two of the battery commanders. Their reports were quite optimistic. "A Battery were wise in shifting from their old position three days ago," he remarked cheerfully. "The old position is getting a lot of shelling; there's nothing falling where they are now. Lots of gas-shelling apparently. It's lucky the batteries had that daily drill serving the guns with gas-masks on."

The doctor and the acting signal officer came into the mess from their quarters farther along the quarry. "If this gas-shelling goes on, I guess we shall all have to have lessons in the deaf-and-dumb talk," puffed the doctor, pulling off his gas helmet. "Keep that door closed!"

"D Battery's line gone, sir," rang up the sergeant-signaller. "M'Quillan and Black have gone out on it."

"Keep Corporal Mann and Sapper Winter on the telephone board to-day," I advised Bliss, the youngster who had come to headquarters the day before to do signal officer. "The colonel will be doing a lot of telephoning, and they know his methods. Be sure to keep all the Scotsmen off the board. The colonel says Scotsmen ought never to be allowed to be telephonists. Impossible to understand what they say."

By 5 A.M. one of the two officers who overnight had manned the forward O.P.'s had spoken to us. He was 2000 yards in front of the most forward battery, but a still small voice sounded confident and cheery, "A few shells have dropped to the right of the O.P., but there's no sign of any infantry attack," was his message. We heard nothing more of him until six weeks afterwards, when his uncle wrote and told the colonel he was safe, but a prisoner in Germany.

5.15 A.M.: The cook was handing round early morning tea. D Battery were through again, and we learned that a sergeant had been killed and one gunner wounded by a 4·2 that had pitched on the edge of the gun-pit. Two other batteries were cut off from headquarters; however, we gathered from the battery connected by the buried cable—that a week before had kept 500 men busy digging for three days—that, as far as they could see, all our batteries were shooting merrily and according to programme.

By 6 A.M. the Brigadier-General, C.R.A., had told the colonel that the situation to left and right was the same as on our immediate front: enemy bombardment very heavy and continuing, but no infantry attack. "We'll shave and have breakfast," the colonel said. "Looks as if the actual attack must be farther north."
