Later, when heavy calls were made upon the German troops to sustain the fighting on the Somme, they were compelled to relax their efforts in this sector, with the result that the British tunnellers established a marked superiority over them.
As soon as the aforementioned blizzard had cleared and commanders could find out the disposition of the men, it became evident that the ground in the forward area was far too thickly held. Orders were in consequence issued for the line to be thinned immediately. Small sectors of disused trenches were dug out to accommodate the surplus men temporarily while a more detailed scheme of defence could be formulated.
The advisability of this measure was soon proved, as from 24th March mines were continually being exploded under or in close proximity to the front line. A typical case occurred on 26th March, when at 2.30 A.M. the enemy fired two mines simultaneously, one on the left of the 152nd Brigade, the other on the right of the 153rd.
These explosions were followed by a heavy bombardment of our front and support trenches with shrapnel, all types of trench-mortar bombs, and rifle and machine-gun fire. A party of about eight Germans then advanced towards the crater in the 153rd Brigade area, but were driven back by two officers and a party of grenadiers. Our losses were severe: 4 officers (1 killed, 2 wounded, and 1 missing) and 74 other ranks (14 killed, 24 wounded, and 36 missing). In addition, there were 24 other ranks suffering from shock. Of these, one company of the 6th Argyll and Sutherland Highlanders lost 2nd Lieutenant M‘Neil and 4 men killed, 5 wounded, and 15 missing. The missing were those unfortunate men who were buried by the falling earth. Of these two craters, the one on the right proved to be seventy yards in length.
On 31st March another mine was fired by the Germans on the front of the 153rd Brigade, with the loss of 1 officer wounded, 6 other ranks killed and 3 wounded. The explosion of this mine was also followed by an intense bombardment by weapons of all natures. A party of Germans then entered a sap. Of these one approached a Jock who had survived the explosion, and pointing his rifle at him, said, “Hands up, Englishman!” The infuriated Jock threw a Mills bomb at the German, having failed to remove the safety-pin, and shouted, “Scotsman, you —— bastard.” The bomb struck the German full on the forehead and felled him. He was captured, and subsequently died in the casualty clearing station from a fractured skull.
The 6th Argyll and Sutherland Highlanders were particularly unfortunate as regards mines, and by the 10th April had already experienced six mines on their fronts.
On 28th April four mines were exploded in front of the 6th Seaforth Highlanders and 8th Argyll and Sutherland Highlanders. The resultant casualties to these two battalions were 6 officers wounded at duty, 12 other ranks killed, 75 wounded, and 30 missing, believed buried. The explosions of these mines were followed by a forty-five minutes’ intense bombardment. The Divisional artillery, however, opened a barrage on the enemy’s lines opposite the newly-formed craters with such rapidity that he was unable to employ his infantry. Throughout the whole period the manner in which the artillery supported the infantry in this form of warfare was admirable, and gave the latter great encouragement.
The explosion of mines became of such frequent occurrence that the troops became very expert in rapidly seizing and consolidating craters. Dumps were made at frequent intervals along the front containing all the materials required for consolidation. In a short time the troops could be relied on to establish themselves on the near lip, however unexpectedly a crater might be blown. This was largely due to the gallantry and initiative of the junior officers, on whose skill and leading success in these enterprises was dependent.
Demonstrations were given in consolidation, and a platoon for each front-line battalion was ear-marked for the consolidation of any mine crater which might be blown on the battalion’s front.
A natural concomitant to mining was sniping. The lip of a crater affords an excellent post from which to snipe, particularly when, as was the case in this sector, the ground sloped from the German position towards the British. The trenches on this sector were also particularly open.
