On 16 August 1916, V Corps HQ was transferred from Second Army to Reserve Army (later renamed Fifth Army) to take over the sector on the River Ancre, where fighting had bogged down during the Somme Offensive. When V Corps took over, the line was held by the Guards, 6th and 20th (Light) Divisions. These were replaced by the fresh 2nd, 39th and 48th (South Midland) Division for the renewed attacks on the Ancre Heights, which continued from September to November 1916 with regular rotation of divisions as they became exhausted. V Corps finally took some of the 1 July objectives, such as Beaumont Hamel (by the 51st (Highland) Division), but ended with a failure at Redan Ridge during the action known as the Battle of the Ancre.
