The first day on the Somme, 1 July 1916, was the beginning of the Battle of Albert the name given by the British to the first two weeks of the 141 days of the Battle of the Somme () in the First World War. Nine corps of the French Sixth Army and the British Fourth and Third armies attacked the German 2nd Army (General Fritz von Below) from Foucaucourt south of the Somme, northwards across the Somme and the Ancre to Serre and at Gommecourt, beyond, in the Third Army area. The objective of the attack was to capture the German first and second defensive positions from Serre south to the Albert–Bapaume road and the first position from the road south to Foucaucourt. The German defence south of the road mostly collapsed and the French had "complete success" on both banks of the Somme, as did the British from Maricourt on the army boundary with the French northwards. XIII Corps took Montauban and reached all its objectives, XV Corps captured Mametz and isolated Fricourt. The III Corps attack on both sides of the Albert–Bapaume road was a disaster, making only a short advance south of La Boisselle, where the 34th Division suffered the most casualties of any Allied division on 1 July. Further north, X Corps captured part of the Redoubt (an earthwork fortification), failed opposite Thiepval and had a great but temporary success on the left flank, where the German front line was overrun and and Stuff redoubts captured by the 36th (Ulster) Division. German counter-attacks during the afternoon recaptured most of the lost ground north of the Albert–Bapaume road and more British attacks against Thiepval were costly failures. On the north bank of the Ancre, the attack of VIII Corps was a disaster, with large numbers of British troops being shot down in no man's land. The VII Corps diversion at Gommecourt was also costly, with only a partial and temporary advance south of the village. The German defeats, from Foucaucourt to the Albert–Bapaume road, left the German defence on the south bank incapable of resisting another attack; a substantial German retreat began from the Flaucourt plateau to the west bank of the Somme close to Péronne. North of the Somme in the British area, Fricourt was abandoned by the Germans overnight. Several truces were observed to recover wounded from no man's land on the British front; the
