Battle of the Ancre Heights: 1 october - 11 November 1916
The Battle of the Ancre Heights is the name given to the continuation of British attacks after the Battle of Thiepval Ridge from 26–28 September
during the Battle of the Somme. The battle was conducted by the Reserve Army (renamed Fifth Army on 29 October) from Courcelette
near the Albert–Bapaume road, west to Thiepval on Bazentin Ridge.[a] British possession of the heights would deprive the German
1st Army of observation towards Albert to the south-west and give the British observation north over the Ancre valley to the German positions
around Beaumont Hamel, Serre and Beaucourt. The Reserve Army conducted large attacks on 1, 8, 21, 25 October and from 10–11 November
