The fire of enfilade machine and Lewis guns was then employed to prevent fresh knife-rests being put in position to replace those which had been damaged. Twenty thousand rounds of S.A.A. were frequently fired in a single night for this purpose.
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.
