The centre section (Field's) were required to advance between the two brigades and plunge into the Hindenburg Line. This movement was made necessary by the decision to attack not on a continuous front but up two slight spurs or shoulders. The Hindenburg Line itself lay just beyond the crest of a slope, and these almost imperceptible shoulders ran out from the main slope at right angles to the line. It was thought that the depression between them would be swept by machine-gun fire, and it was decided in consequence to leave the attack up the depression to the tanks alone.

My left section (Swears') were to precede the infantry of the left Australian brigade. They were to obtain a footing in the Hindenburg Line and then work along it into Bullecourt. Whether, later, they would be able to assist the British infantry in their attack on the trenches to the west of Bullecourt was a matter for their discretion.

The atmosphere of the conference was cheerless. It is a little melancholy to revive and rebuild the plan of an attack which has been postponed very literally at the last moment. The conference was an anticlimax. For days and nights we had been completing our preparations. The supreme moment had come, and after hours of acute tension had passed without result. Then again, tired and without spirit, we drew up fresh plans. War is never romantic because emergencies, which might be adventures, come only when the soldier is stale and tired.

We hurried back to the camp at Behagnies and composed fresh orders, while Jumbo re-marked his maps and reshuffled his aeroplane photographs. At dusk Jumbo and I started out in the car for Noreuil, but at Vaulx-Vraucourt we decided to leave the car as the road was impossible. It was heavy with mud and slush and we were far from fresh. We passed Australians coming up and much transport​—​in places the road was almost blocked. After an hour or more we came to the valley above Noreuil, full of new gun-pits. Our tanks lay hidden against the bank at the side of the road, shrouded in their tarpaulins. My men were busily engaged in making them ready. One engine was turning over very quietly. It was bitterly cold, and the snow still lay on the downs.

We struggled on to a ruined house at the entrance to the village. One room or shed​—​it may have been a shrine​—​constructed strongly of bricks, still stood in the middle of the wreckage. This my officers had made their headquarters. I gave instructions for all the officers to be collected, and in the meantime walked through the street to one of the two brigade headquarters in the village.

This brigade was fortunate in its choice, for it lay safe and snug in the bowels of the earth. An old brewery or factory possessed whole storeys of cellars, and the brigade office was three storeys down.

Haigh and Swears were discussing operations with the brigadier. They were all under the illusion that the postponed attack would take place as originally planned, and bitter was the disappointment when I told them that the orders had been changed. I gave the general and his brigade-major a rough outline of the new scheme, and took Swears and Haigh back with me to the ruins.

All my officers were assembled in the darkness. I could not see their faces. They might have been ghosts: I heard only rustles and murmurs. I explained briefly what had happened. One or two of them naturally complained of changes made at such a late hour. They did not see how they could study their orders, their maps, and their photographs in the hour and a half that remained to them before it was time for the tanks to start. So, again, I set out carefully and in detail the exact task of each tank. When I had finished, we discussed one or two points, and then my officers went to their tanks, and I returned to brigade headquarters, so that I might be in touch with the colonel and the Division should anything untoward happen before zero.

The night passed with slow feet, while my tanks were crawling forward over the snow. The brigade-major re-wrote his orders. Officers and orderlies came in and out of the cellar. We had some tea, and the general lay down for some sleep. There was a rumour that one of the tanks had become ditched in climbing out of the road. I went out to investigate, and learned that Morris's tank had been slightly delayed. It was, unfortunately, a clear cold night.
