At the end of October it was realised that these knife-rests were being employed by the enemy in most formidable numbers, and were becoming a serious proposition.
A number of Bangalore torpedoes were therefore made and carried up to the trenches. Raiding parties then carried these torpedoes into No Man’s Land with them, and blew gaps in the rows of knife-rests. On 1st November a particularly good raid of this nature was carried out. Lieutenants Booth and Carnie of the 6th Gordon Highlanders with a party of men placed four torpedoes under the enemy knife-rests. These were exploded, and after a short interval the officers led the party through the gap caused by the explosions. They then exploded four more torpedoes under the next double rows of knife-rests. The party returned without a casualty, and reported that still a third row of knife-rests existed beyond the last one they had damaged.
Raiding parties had also been employed to enter the enemy’s trenches to gain identifications—that is, to return with evidence as to what units were holding the line in front of the Division.[6]
On 26th October both the 6th Black Watch and the 7th Gordon Highlanders of the 153rd Brigade entered the enemy’s front line, the latter capturing a prisoner of the 62nd Regiment. On the same night the 7th Argyll and Sutherland Highlanders of the 154th Brigade made a similar attempt, but could not find a passage through the enemy’s wire. In the raid of the 7th Gordon Highlanders, Lance-Sergeant Morrison killed four Germans and disarmed a fifth, who was taken prisoner. At this point Sergeant Morrison had expended all his ammunition and bombs, and was faced by two more Germans with fixed bayonets. Appreciating the situation, Private Louis Thomson rushed past Sergeant Morrison and killed the first German with his entrenching tool. He then picked up the fallen German’s rifle and with it killed the second. For this exploit both Sergeant Morrison and Private Thomson were awarded the Military Medal.
On 29th October a patrol of the 154th Brigade entered the enemy’s front line and proceeded to his second line, which they found protected by an impassable belt of knife-rests. This patrol encountered none of the enemy. The absence of the Boche on this occasion proved rather disconcerting. In consequence, the 4th Gordon Highlanders and the 9th Royal Scots carried out further raids. In each case they found the enemy holding the trenches in strength, and were unable to effect an entrance. This was partly due to the fact that the ground was so sodden that the troops found it a physical impossibility to keep up with the barrage.
A further raid attempted on 4th November by the 6th Gordon Highlanders also met with strong resistance, and made no progress. It was therefore almost impossible to form an impression of the strength in which the enemy was holding his line.
On 31st October a deserter entered our lines. He was a miserable creature, described officially as “undersized and of poor physique.” He stated on examination that the battalion was holding a front of only 700 yards, and that the rifle strength of the four companies was about 180 each. His statement, if it was accurate, meant that the enemy was holding the position in considerably greater force than was probable. In view of his apparent poverty of intellect, it was considered that his evidence was unreliable. It, however, transpired during the attack that his statements were not exaggerated, and that the enemy was indeed very thick on the ground.
The final preparations for the attack consisted in forming dumps of ammunition, water, rations, &c., sufficiently far forward to enable carrying parties to take forward supplies to the advanced troops after the capture of the enemy’s position.
This was a heavy task, as the following figures of supplies which were carried through the water-logged trenches and placed in the brigade dumps testify:—
