At "zero" I was standing outside my tent. There was thick mist in the valley. Through some freak of the atmosphere I could only just hear the uneven rumble of the guns. It was so cold that I went in to breakfast.

Half an hour after "zero" my tank engineer and I set out in my car to catch up with the battle, giving a lift on the way to a pleasant young subaltern in the R.H.A. returning from leave, who was desperately eager to find his battery. We left the car stupidly at Fouilloy,​—​we might have taken it farther forward,​—​and tramping up the Villers-Brettoneux road, cut across country, among invisible guns, through the mist, which did not clear until we reached what had been the German trenches.

Apparently we had repeated Cambrai. Companies of prisoners, stout-looking fellows, were marching back in fours. Here and there lay German dead on the rough coarse grass, or in the shallow unconnected trenches. A few hundred yards to our right was the Roman road that runs west from Villers-Brettoneux. Light-armoured cars of the 17th Battalion, with the help of tanks, were picking their way through the shell-holes.

Just short of a large ruined village, Warfusée-Abancourt, straggling along the road, and two miles from our old front line, we found a little group of supply tanks with a couple of waggons. One waggon suddenly had exploded on the trek forward. Nobody had heard the noise of an approaching shell, and we suspected a trip-mine, with which the battlefield was sown. We were discussing its fate when a large German aeroplane swooped down and drove us to take cover. A British aeroplane appeared, but the German forced it to land hurriedly. And the enemy began to send over a few small shells.

We moved forward unobtrusively, Read, myself, and Puddy, my orderly, to an inconspicuous knoll. There we lay in comfort, watching the farther advance of the Australians. The country was quite open and bare, though broken with unexpected valleys. A slight breeze had swept away the mist, and the morning was bright and sunny. A few hundred yards in front of us the Australians were walking forward nonchalantly, led by a score of tanks. Occasionally a shell would fall among them and they would scatter momentarily, but it was rarely that a man was left upon the ground. From the valley beyond, which we could not see, came the rattle of Lewis guns, and once or twice bursts from the enemy machine-guns. To the left and behind us our field-guns, drawn up in the open, were firing for dear life, and away to the right along a slight dip a battery of field-guns was trotting forward. Overhead the sky was loud with the noise of our aeroplanes, some flying low above the battle and others glistening in the sun high among the clouds.

The Australians disappeared with the tanks over the skyline, and the supporting infantry in little scattered bodies passed us, marching forward cheerily over the rough grass. We were already three miles within the enemy defences.

We pressed on northwards to the Cérisy Valley, which we knew had been full of German field-guns. This deep gully, with steep grassy sides, fringed with stunted trees, runs from the tiny village of Cérisy-Gailly, on the south bank of the Somme, to Warfusée. Our gunners had done their work with terrible thoroughness. The bottom of the valley was so broken with shell-holes that it was barely possible to drive a limber between them. Four or five of the enemy guns remained desolate among a wild confusion of shattered waggons and dead horses. A trembling pony, still harnessed to his dead fellow, was the only survivor.

A hundred yards down the valley tanks were climbing the steep bank, and the flag of a tank battalion fluttered bravely on the crest.

We crossed the valley, toiled up the farther slope, and munched some sandwiches on the hill, where sappers were calmly marking out new trenches. At a little distance a shabby Australian field-battery was in action.

In a few minutes we saw something of the display and gallantry of war. A battery of Horse Artillery picked its way across the valley. The men were clean, inconceivably clean, and smart. Their horses' coats gleamed. The harness shone and glittered. The guns were newly painted. Never could a battery more splendidly arrayed have entered the plebeian turmoil of a battle. A series of swift commands and the little guns, with their ridiculous bark, were firing impudently. The Australians were overshadowed​—​their horses were unkempt and the guns dirty​—​but they had got there first.[29]
