The Ancre is a river of Picardy, France. Rising at Miraumont, a hamlet near the town of Albert, it flows into the Somme at Corbie. It crosses no départements other than the Somme.
The Battle of the Ancre (13–18 November), was the final large British attack of the Battle of the Somme in 1916. After the Battle of Flers–Courcelette on 22 September, the Anglo-French armies tried to press their advantage with several smaller attacks in quick succession, rather than pause to regroup and give the German armies time to recover. Subsequent writers gave discrete dates for the Anglo-French battles but there were considerable overlaps and continuities of operations, until the weather and supply difficulties in mid-November ended the battle until the new year. It was fought by the Fifth Army (the Reserve Army had been renamed on 30 October) under the command of Lieutenant-General Hubert Gough, against the German 1st Army (General Fritz von Below).
The intent of the British attack was to fulfil complementary objectives. Political discontent in London would be muted by a big victory, as would doubts of British commitment by its allies; British loyalty to the Chantilly strategy of 1915 would be seen to be upheld and the capture of Beaumont Hamel and Serre would go some way to redeem the failure of 1 July and obtain ground on which the British would have a tactical advantage. The attack was the largest in the British sector since September and had a seven-day preliminary bombardment, which was twice as heavy as that of 1 July. Beaumont Hamel, St. Pierre Divion and Beaucourt were captured, which threatened the German hold on Serre further north. Edmund Blunden called the battle "a feat of arms vieing (sic) with any recorded. The enemy was surprised and beaten". Four German divisions had to be relieved due to the number of casualties they suffered and over 7,000 German troops were taken prisoner.
