With the results of the day's fighting on other parts of the front we are hardly concerned here. From Fricourt to the Somme the day was successful and the bulk of the objectives were captured and held. But from Fricourt northward the tale throughout was one of complete check. Everywhere our troops met with initial success which everywhere was later changed into disaster with appalling losses.
There is no doubt that in the northern half of attack the British offensive was fully anticipated by the Germans. It would indeed have been difficult to carry out such immense preparations over a period of several weeks prior to the battle without permitting indications of the impending attempt to become visible to hostile aerial scouts. But it had been hoped that the weight and long continuance of the preliminary bombardment, even though it disclosed its own purpose, would prove so intense as to nullify all the German efforts to resist.
We must here make some reference to the battle of the 46th Division on the northern face of the Gommecourt salient. Against this ill-fated Division the German fire was terrific. On the right the South Staffords were completely shattered by the enemy's machine-guns before they could cross No Man's Land; on the left the Sherwood Foresters succeeded in gaining the German front line, and isolated parties appear even to have struggled forward as far as the second trench, but were rapidly ejected. Soon after zero the whole of the 46th Division's assaulting troops were back in their own line after suffering appalling losses: their attack was a complete failure. At the time, therefore, that the 56th Division was making headway into the German positions, instead of the enemy feeling, as had been hoped, the pincers closing on him from both sides of his salient, he was relieved from all menace on his right flank facing the 46th Division, and free to throw the whole weight of his artillery and infantry against the 56th Division.
But the causes of the 56th Division's failure must be looked for deeper than this.
Primarily it may be said to have been due to the shortage of bombs. The great distance which carrying parties had to traverse over No Man's Land with fresh supplies and the intensity of the German barrage through which they had to pass were both such that the facilities for getting bombs forward were inadequate. It should be remembered that the 168th and 169th Brigades captured three lines of German trenches and held them against all attacks in spite of the gruelling enemy fire for many hours. It was only when bomb supplies failed that they were ejected.
There are three other factors in this battle to which we may refer as having contributed to the failure.
First, the enormously strong deep dugouts in the German lines, which were large enough to give shelter to the whole trench garrison except the few necessary sentries, had proved too strong for all except the heaviest guns; and those of the heaviest calibre had not been directed against them. The German garrisons were therefore able to remain in safety until the last moment when our barrage lifted off their front lines and they were able to man their parapets. The strength of the German defences was increased by the density and depth of their wire entanglements, which had been most skilfully sited with the support of machine-guns firing in enfilade.
Secondly, the insufficient attention paid on our side to counter-battery work. The batteries told off for counter-battery fire were too few and of too light calibre. Throughout the day the cry arose from all Headquarters to silence the German guns, but the few batteries available, though served magnificently by splendid gunners, could not cope with so gigantic a task.
The third and most important cause lay in the cunning skill with which the German barrage was used. We have referred above to the manning of the German parapets by their garrisons after our barrage had passed over; but not in every case did this happen. In many instances a greater refinement of skill was exhibited. As the British barrage lifted off the first objective and the leading waves of the assault poured over it, down came the enemy barrage like a dense curtain, cutting them off for ever from their supports and their supplies. The barrage having thus trapped them, the front trench filled with Germans swarming up from their subterranean shelters, and these poured a hail of machine-gun fire into the backs of our waves which were pushing forward to the next line.
