On this occasion the raiders met with, if anything, severer fighting than had the 6th Gordon Highlanders. The wire had on one flank either been repaired or the party had made a slight error in their direction, so that on this flank the barrage was lost, and the troops had to complete their advance to the trench without its protection.
The raid was, however, successful, most squads reaching their objective and overcoming all resistance encountered. Our casualties amounted to 8 officers and 102 other ranks, of whom, as before, many were only lightly wounded. The casualties appear heavy—and, indeed, were heavy—but it must be borne in mind that in any trench fighting in which bombs are freely used, a number of lightly wounded men is an inevitable result. The enemy, suspecting that another raid might be attempted, had reinforced his trench garrison, and was in considerable strength. In consequence, he suffered serious losses.
The raids were of great value to the battalions which carried them out, as both were destined on “the day” to pass over the same area as they had raided. The enemy’s wire and trenches had been reduced to an almost irreparable condition. The men had had a further experience of following the creeping barrage, which had been fired without a fault, and had given him the greatest confidence. The artillery, including the 64th Army Brigade R.F.A. attached to them, had twice fired a barrage over a portion of the front to be covered by them in the battle.
The raiders expressed themselves as delighted with the shrapnel barrage. The men again reported that they were able to wait in the remnants of the enemy’s wire entanglements while the barrage was still on his front line.
Moreover, the heavy work of clearing the old French trench, in which the troops for the main attack were to assemble, had also been completed at least on one battalion frontage.
The disadvantage that came from these raids was that the casualties had been fairly heavy, and affected chiefly one company in each battalion. Thus, when the day of attack came, these companies contained an undue proportion of inexperienced reinforcements.
On 31st March the 6th Black Watch raided a small salient in the left brigade front with two parties, together totalling 2 officers and 50 men. Preparatory to this raid, and also as a blind to the two raids described above, much wire had also been cut on this brigade front. In spite of this, one of the parties was unable to effect an entry into the enemy’s trenches. The second party was, however, successful, but the trench was found to be only lightly held. Two dug-outs were bombed, six men were killed, and the 2nd Bavarian Reserve Infantry Regiment was identified as still holding the line.
It had now become clear that if the Division was to be opposed in the big attack by these Bavarians, it would meet an enemy who would offer the maximum of resistance. It therefore was a matter of first importance to ensure that the men fully understood that success would depend on the speed with which they reached the enemy parapet after the barrage had left. It may be said that there would be a race for success. While the barrage was on the trench, the Bavarians would be on the dug-out step, and the Highlanders would be waiting from seventy to a hundred yards short of the trench. As the barrage lifted the race began. Would the Bavarian reach his fire-step and open fire on the Highlanders, or would the Highlanders reach the parapet and shoot the Bavarian down before he could man his trenches?
The men learnt to appreciate this fact, and all developed the fixed determination that they would stick close to the barrage whatever else might happen. The result was that when the day came in the first phase of the battle the issue was never in doubt.
The plan of the attack was as follows: A frontage of just over 3000 yards, gradually increasing up to 4000 yards, was allotted to the Highland Division. The depth to which it was hoped the attack would be carried was 5500 yards. The 152nd Infantry Brigade was to attack on the right, the 154th Brigade on the left; on the right of the Division the 34th Division carried on the attack, and to the left the Canadian Corps. The Highland Division was the left flank Division both of the XVIIth Corps and of the Third Army.
