Across the foreground of the picture ran the great highroad from Bapaume to Cambrai. It was wide, perfectly straight, and fringed with orderly trees. Beyond it and to my left was a low hill, which the enemy still held. Our line ran diagonally up the slope of it, and away to the west we were on the ridge. Immediately in front of me on the hillside was the great dark mass of Bourlon Wood, square and impenetrable, covering the highest point of the hill and stretching over the skyline to the farther slope, which we could not see. The wood dominated the whole countryside, and beyond it there was nothing but low open country, extending to the marshes of the Scarpe. We could not live north of Havrincourt while the enemy held the wood, and if we captured the wood there was nothing to prevent us from sweeping northwards to the Scarpe or westwards into Cambrai. At the moment our line ran along the southern outskirts of the wood and to the south of Fontaine, which the enemy held in force.

At 10.30 A.M. the barrage fell and we could see it climb, like a living thing, through the wood and up the hillside, a rough line of smoke and flame. On the hillside to the left of the wood we could mark the course of the battle,​—​the tanks with tiny flashes darting from their flanks​—​clumps of infantry following in little rushes​—​an officer running in front of his men, until suddenly he crumpled up and fell, as though some unseen hammer had struck him on the head​—​the men wavering in the face of machine-gun fire and then spreading out to surround the gun​—​the wounded staggering painfully down the hill, and the stretcher-bearers moving backwards and forwards in the wake of the attack​—​the aeroplanes skimming low along the hillside, and side-slipping to rake the enemy trenches with their guns.

We watched one tank hesitate before it crossed the skyline and our hearts went out to the driver in sympathy. He made his decision, and the tank, brown against the sky, was instantly encircled by little puffs of white smoke, shells from the guns on the reverse slope. The man was brave, for he followed the course of a trench along the crest of the hill. My companion uttered a low exclamation of horror. Flames were coming from the rear of the tank, but its guns continued to fire and the tank continued to move. Suddenly the driver must have realised what was happening. The tank swung towards home. It was too late. Flames burst from the roof and the tank stopped, but the sponson doors never opened and the crew never came out.... When I left my post half an hour later the tank was still burning....

At noon I determined to push forward into the wood and discover what had happened to my tanks. We skirted the village, walked along a sunken road lined by dug-outs, and started to cross the low ground between us and the road. I at once began to wonder whether it was not perhaps a little early yet to go forward. The path to the highroad was the object of direct or indirect machine-gun fire, and an officer, who was sitting in a trench, told me cheerfully that Cooper and Smith, his second-in-command, had already been hit by chance bullets. We pushed on, however, to the inn on the highroad, and as the road was being shelled, we took to the ditch until a shell, bursting in the ditch itself, persuaded us to use the road. We did not get very far, and soon we returned to the top of the bank at the side of the sunken road. By this time "G" Battalion were beginning to arrive and their tanks were moving across to Anneux Chapel.

After lunch I went forward again and reached a clearing on the south side of the wood, where the tanks had been ordered to rally. The enemy must have realised our intention, for the clearing was being shelled most systematically. The only tank in the clearing belonged to another battalion. The crew, realising their danger and a little lost, evacuated their tank and joined me in a small quarry where I had temporarily taken cover.

I left the quarry during a lull and walked up a sunken road into the wood, but I soon realised, first, that I should never find my tanks by tramping after them, and second, that I should be infinitely happier in my quarry. So I returned and spent the next hour in watching the rallying-place and in moving at intervals from one side of the quarry to the other. The news was moderately good. The 40th Division, assisted by my few tanks, had driven the astonished Germans to the further fringes of the wood, and were now mopping up a few pockets of the enemy who were still holding out in the vain hope that they would be rescued by counter-attacks. But on the right​—​so I was told by two immaculate young cavalry subalterns who were reconnoitring forward​—​Fontaine was defying our sternest efforts.

About three I saw a couple of tanks cross the road at the inn, three-quarters of a mile away. So, as one shell had already burst on the lip of the quarry, I hastened to the cross-roads at Anneux Chapel on my way back to Graincourt. At the cross-roads I met an infantry battalion coming up to complete the clearance of the north-west corner of the wood. The Colonel asked me whether my tanks would assist him. I told him that they were already in action. It was indeed a pity that "G" Battalion, which did not arrive until after the main portion of the wood was in our hands, had not been held in reserve for such an emergency.[20]

I reached battalion headquarters about 4 P.M. Both Bourlon village and Fontaine-Notre-Dame were holding out. It was reported, too, that "E" Battalion had suffered very heavily.

I walked along to my dug-out, where I discovered that the majority of my tanks had already returned in safety. They had realised the danger of rallying at the clearing and had come back direct to their starting-point, followed all the way by the German gunners.

Two of the tanks, commanded by Lloyd and Hemming, had successfully crossed the ridge and entered Bourlon village, but the infantry were prevented by the intense machine-gun fire from occupying the place. Two more of my tanks had experienced such concentrated machine-gun fire themselves that every man in them was wounded by flying splinters, including Wyatt, who had commanded his section from a tank.
