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. 164th Brigade on the left was to attack Guillemont village with two battalions assisted by two companies of 1/4th Loyals, then the remaining two companies of 1/4th Loyals were to follow up and occupy the German front line. On each of the two days before the attack, D Company attempted to seize an enemy-held ridge 150 yards in front of the division's start-line, but failed. The attack (the Battle of Guillemont) was not a success. The only progress was on the left where 1/8th Bn Liverpool Regiment (the Liverpool Irish) went through the village and D Company 1/4th Loyals moved up to consolidate the gains. However the enemy got between them and the Liverpool Irish, forcing D Company to retire. The support companies were not engaged, but still suffered heavy casualties from artillery fire. The battalion had to be brought up to strength with a draft of over 200 men from the Manchester Regiment and the East Lancashire Regiment.
