The 55th Division launched its first attack on Guillemont at dawn on 8 August, supported by the divisional artillery firing a new-style Creeping barrage. However, the centre of the attack was held up and the barrage had to be brought back. In the end the attack failed with heavy casualties, as did its renewal next morning, when the infantry advanced without a preliminary bombardment but protected by the creeping barrage. The division made a further failed attack on Guillemont on 12 August. The artillery was briefly rested on 15 August, but was back in action for the early September fighting on the Somme: the battles of Guillemont (4–6 September) and Ginchy (9 September). The latter was an afternoon attack after the field artillery had carried out a deliberate bombardment in the morning, followed by firing the now-familiar creeping barrage. The attack was only partially successful, but the division saw better results in its attack on Gueudecourt during the Battle of Morval (25 September). This time the infantry kept close to their barrage and took their first and second objectives with ease. They repeated the success two days later in taking some stubborn German strongpoints and the retreating enemy were caught in the open by the divisional artillery, which also broke up a German counter-attack. Casualties in the artillery brigade during August had been predominantly due to accidents such as premature explosions of faulty ammunition, and in September had been concentrated in the waggon lines, which were bombed nightly. The guns were relieved on 28 September and moved to the Ypres Salient.
