The area from Maurepas to Guillemont and Ginchy, was taken over by the 27th Division which was still contained four regiments. North of the Somme, the French attacked the positions of Reserve Infantry Regiment 17, on high ground around Hem during 7 August. In a combined Franco-British attack on 12 August, the British infantry reached Guillemont but two battalions diverged. German troops made their way north-east through the gap, to re-establish the front line, as other units advanced from the village, where the dug-outs had several exits. III Battalion, Infantry regiment 124 engaged the British in the village, as III Battalion, Infantry Regiment 123 was pushed back into Guillemont, by an attack from the north. When II Battalion, Infantry Regiment 124 and II Battalion, Grenadier Regiment 123 arrived, the counter-attack was resumed and gradually overran the British in and around the village. The southern part of Maurepas and the cemetery were lost, after of battle, when German artillery-support failed due to lack of observation. The area between Cléry and Maurepas had been held and counter-attacks were made by the 5th Bavarian Reserve Division, which was rushed forward after 13 August, to reinforce the defence. A British document was captured near Guillemont, containing German phrases intended to mislead the defence. On 16 August, Infantry Regiment 127 was relieved by battalions of regiments 123 and 124, which had only been withdrawn four days earlier. By 18 August, when the division had lost the British attacked again.
