On 25 July the 55th Division was relieved and travelled south to join in the Somme offensive. It moved into the line opposite Guillemont on 30 July and prepared to attack on 8 August (the Battle of Guillemont). 164th (North Lancashire) Brigade made the initial attack, and 1/5th Loyals moved out early on to support it. B and C Companies were sent on to occupy trenches running north between the Trones–Guillemont road and Railway Support Trench, C Company then continuing to join 1/8th Bn King's Liverpool Regiment (the Liverpool Irish) in the front line. Soon afterwards A and D Companies were ordered up to join 2/5th Bn Lancashire Fusiliers. However, the attack had failed with heavy casualties and the division was ordered to repeat it the following day. This time 1/5th Loyals and the 1/10th King's Liverpool (Liverpool Scottish) were to lead. There was no preliminary bombardment, only a short covering barrage beginning at 04:20. The Liverpool Scottish followed this barrage closely and got as far as the enemy wire, which was uncut. But because of the late arrival of the orders and the crowded trenches on the way up, the 1/5th Loyals could not get into position until after 05:00, long after the barrage had ended. Nevertheless, the battalion 'made a most gallant assault' at 05:25; unable to reach the enemy trenches they were forced back to their starting point. Every officer with the right hand companies became a casualty. Battalion losses totalled 33 killed, 85 wounded and 20 missing.
