On the 18 of August, the Argylls were preparing to take over the trenches, moving in on the 19 to relieve the 10 Scottish Rifles in preparation for the attack on Martinpuich. The battalion took over the front at 9am as the enemy shelled the line, causing the Argylls eight men killed and eighteen wounded before noon. The line was then consolidated, patrols were sent out to ‘peacefully penetrate’ toward the enemy trenches.
At 5pm on August 20, ‘D’ Company filed through the barricade at the end of Welsh Sap trench and into Sanderson Trench but met no enemy opposition. They took three Saxons prisoner, who informed the Highlander officers that the trench had been evacuated several days previously.
The Argylls then consolidated their new positions in Sanderson Trench, before a working party from ‘C’ Company was set off from Pioneer Sap to the Switch Line. The working party was to dig a trench up to the junction of the Switch Line and the Martinpuich to Bazentin Le Petit road to form a strong post.
Lieutenant Hutcheson was sent to check on the condition of the heavily damaged ground before any movement was made, but a sniper shot him. (See Murdo Mackay, Skerray).
The battalion then consolidated it’s new positions by building strong points on a road junction and along the front line, ‘C’ Company lost direction but did dig out Pioneer Alley. The Argylls remained in the front line until the 23 of August before being relieved by the 6/7 Battalion, Royal Scots Fusiliers.
