Beyond the enemy trenches the slopes, from which the German gunners might have observed the advancing tanks, were already enveloped in thick white smoke. The smoke-shells burst with a sheet of vivid red flame, pouring out blinding, suffocating clouds. It was as if flaring bonfires were burning behind a bank of white fog. Over all, innumerable aeroplanes were flying steadily to and fro.

The enemy made little reply. A solitary field-gun was endeavouring pathetically to put down a barrage. A shell would burst every few minutes on the same bay of the same trench. There were no other enemy shells that we could see. A machine-gun or two were still trained on our trenches, and an occasional vicious burst would bring the venturesome spectator scrambling down into the trench.

Odd bunches of men were making their way across what had been No Man's Land. A few, ridiculously few, wounded were coming back. Germans in twos and threes, elderly men for the most part, were wandering confusedly towards us without escort, putting up their hands in tragic and amazed resignation, whenever they saw a Highlander.

The news was magnificent. Our confidence had been justified. Everywhere we had overrun the first system and were pressing on.

A column of tanks, equipped with a strange apparatus, passed across our front to clear a lane through the wire for the cavalry.

On our left another column of tanks had already disappeared into the valley on their way to Flesquieres. It was Ward's company, but Ward was not with them. A chance bullet had killed him instantly at the head of his tanks. When we heard of his death later, the joy of victory died away....

At 8 A.M. Cooper, Jumbo, a couple of runners, and myself started after our tanks. We questioned a group of Germans, who confessed that, while they had expected a raid in a day or two, they had known nothing of the tanks. We jumped down into the famous Hindenburg Line. At first we were unhappy: a machine-gun from the right was enfilading the trench and the enemy gunners were still active. We pushed along to the left, and after a slight delay came to a deep sunken road, which cut through the trench system at right angles.

We walked up the road, which in a few yards widened out. On either side were dug-outs, stores, and cook-houses. Cauldrons of coffee and soup were still on the fire. This regimental headquarters the enemy had defended desperately. The trench-boards were slippery with blood, and fifteen to twenty corpses, all Germans and all bayoneted, lay strewn about the road like drunken men.

A Highland sergeant who, with a handful of men, was now in charge of the place, came out to greet us, puffing at a long cigar. All his men were smoking cigars, and it was indeed difficult that morning to find a Highlander without a cigar. He invited us into a large chamber cut out of the rock, from which a wide staircase descended into an enormous dug-out. The chamber was panelled deliciously with coloured woods and decorated with choice prints. Our host produced a bottle of good claret, and we drank to the health of the Fifty-first Division.

A few German prisoners, with a large, stiff sergeant-major at the head of them, were halted outside while their escort snatched a hurried breakfast. The sergeant-major was trying earnestly to make himself understood. He seemed to have something important to say. His escort became impatient and irritated, but, before proceeding to more summary punishment, the corporal in charge brought him to me.
