The Somme Offensive continued, with some success for X Corps on 14 July (the Battle of Bazentin Ridge), 17 July (the Capture of Ovillers) and 23 July (the Capture of Pozières. The front was then reorganised, with Reserve Army (later Fifth Army) taking over the sector from Fourth Army and X Corps HQ handing over to II Corps. There as no respite for the gunners: II Corps continued the Battle of Pozières Ridge until early September and was then engaged in the battles of Flers-Courcelette (15–22 September) and Thiepval Ridge (26–28 September), with the heavy guns increasingly concentrated to help the infantry advance. On 3 October 70th Siege Bty transferred to 16th HAG, still with Fifth Army, which continued to attack on the Ancre Heights until mid-November, and minor operations there through the winter.
