The whole position up to and including the Green line had been captured with over two thousand prisoners and a vast amount of material in a few hours. Moreover, had the positions of the Divisions on the flanks been less obscure, an advance to the Yellow line could have been undertaken with every prospect of success.
The satisfactory results of these operations may be put down to the following causes:—
First, to the resolution and gallantry of the officers and men. In spite of heavy losses and of the appalling state of the ground, they pressed on to their objectives with the greatest determination. In many cases the barrage was irretrievably lost. The resistance of a courageous and cunning enemy, protected by the strongest field defences that experience could devise, had then to be overcome by the superior fighting qualities of the infantry soldier alone. The manner in which he overcame this resistance was in accordance with the highest traditions of the Highland regiments.
The artillery played no small part in this battle. The heavy gunners had demolished the enemy’s trenches in an exemplary manner. In the village of Beaumont Hamel there was barely a square yard that was not torn up by shell-fire. The deep dug-outs alone escaped destruction, and even in their case many entrances were blown in. A German battalion headquarters sustained three direct hits, all of which went through the roof. In one case two layers of reinforced concrete and one layer of tree-trunks had been penetrated. In the enemy front line machine-gun emplacements, made of concrete over a metre thick, were in many cases wrecked.
Both the destruction of the wire and the accuracy of the barrage further strengthened the great confidence of the infantry in the Divisional artillery. It was the first occasion on which most of the troops had followed an artillery barrage. Those who were able to keep up with it could not speak too highly of its accuracy.
The decision to have no preliminary bombardment immediately before the attack proved to have been a wise one. Such a bombardment would only have served to warn the enemy of our intention to attack. As it was, the infantry began their advance the moment the artillery opened. They were thus able to assault the front line within a few seconds of the barrage having lifted. The enemy was in consequence to a large extent taken by surprise, and large numbers of them were captured before they had had time to leave their dug-outs.
The enemy had, however, this advantage. It could not be told whether a shaft was the entrance to a dug-out or to a tunnel connecting two lines of trenches. As a result, it was difficult to ensure that any particular trench would remain cleared of Boches. The large traversed dug-outs were also difficult to clear up. A Mills bomb did not seem to have much effect on their occupants. A phosphorus bomb, however, bolted eighty-six Germans in all stages of undress out of a single dug-out.
The machine-gun barrage appeared to have been very effective. The 7th Gordon Highlanders reported a considerable number of German dead between the Green and Yellow lines who are believed to have been caught in this barrage. The machine-gunners who went forward with the attacking waves also executed their tasks admirably.
Vickers guns were in position in the German front line within half an hour of zero. One gun-team had some close-range fighting with revolvers and bombs, and captured seventeen prisoners, not, however, before the section officer had been wounded and a sergeant killed.
Vickers guns were assigned definite roles in the consolidation and were placed in depth throughout the captured area. Several guns took up advanced positions well east of the Green line.
