The Attack on the Gommecourt Salient was a British operation against the northern flank of the German 2nd Army that took place on 1 July 1916, on the Western Front in France, during the First World War. The attack was conducted by the British Third Army (Lieutenant-General Edmund Allenby) as a diversion, to protect the northern flank of the main attack by the British Fourth Army on the first day of the Battle of the Somme, from Serre southwards to the boundary with the French Sixth Army at Maricourt.
