Battle of Flers–Courcelette

Battle context

The Battle of Flers–Courcelette formed the third phase of the Battle of the Somme, launched by the British Fourth Army, the Reserve Army, and the French Sixth Army against the German 1st Army. The Anglo-French attack opened on 15 September and concluded on 22 September without achieving the strategic objective of a decisive breakthrough. Nevertheless, the operation produced a considerable tactical result: the villages of Courcelette, Martinpuich, and Flers were captured, and heavy casualties were inflicted on the German front divisions. British losses stood at over 29,000 while German casualties were recorded at approximately 130,000. The battle thus advanced the attritional logic of the Somme campaign without resolving it, adding territorial gains to the cumulative pressure on German defensive strength while leaving the broader strategic deadlock intact.
