The Battle of Aubers (Battle of Aubers Ridge) was a British offensive on the Western Front on 9 May 1915 during the First World War. The battle was part of the British contribution to the Second Battle of Artois, a Franco-British offensive intended to exploit the German diversion of troops to the Eastern Front. The French Tenth Army was to attack the German 6th Army north of Arras and capture Vimy Ridge, preparatory to an advance on Cambrai and Douai. The British First Army, on the left (northern) flank of the Tenth Army, was to attack on the same day and widen the gap in the German defences expected to be made by the Tenth Army and to fix German troops north of La Bassée Canal.
