The Battle of the Ancre 13–18 November, was the final large British attack of the Battle of the Somme in 1916, before winter. 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.
