 to midway between Beaucourt and Miraumont, and on the 10th February the Thirty-second Division took in hand the business of shifting the enemy out of what remained to him in the Beaumont Valley. Their advance brought Serre village into direct danger from our artillery, and any further move on our part up the valley of the Ancre would make Serre untenable.

On the 17th February that move was made by three Divisions (Second, Eighteenth, and Sixty-third) before dawn, through heavy mist on the edge of a thaw, and in the face of a well-contrived barrage that caught the battalions forming up. But the positions and observation-points, already gained, helped our guns to help the infantry, broke up the enemy's counter-attacks with satisfactory losses, and, in the next few days, gave us good command over the enemy's artillery dispositions in the valley of the Upper Ancre and a fair look into his defences at Pys and Miraumont. Then the game stood thus: If Miraumont, which lay at our mercy, were taken, Serre would go; if Serre went, Puisieux-au-Mont and Gomiecourt, the pillar of the old German western defences, would be opened too; and it was no part of the German idea to cling to untenable positions, whose loss would have to be explained at home where people were asking why victory delayed so long. Not only was the whole of Arras-Le Transloy salient shaking by now; there was the prospect of indefinite wastage to no good end all along the rest of the Somme front, and though the weather, till then, had blunted the following weight of each following blow, many considerations pointed to a temporary withdrawal of a few miles in order to advance the more irresistibly at a more fitting time. Slowly, methodically then, with careful screens of veiled machine-guns behind them, and a series of scientifically chosen artillery positions, equally capable of supporting a counter-attack, or checking and destroying any too inconvenient body of pursuers, the enemy moved back into ground not yet churned and channelled by shell or traffic, over
