無人地帯
The 92nd Brigade held the front line trenches during the British bombardment in the days leading up to the battle, suffering significant casualties from the German counter-bombardment. The night before the battle, working parties from the 92nd Brigade were out in No man's land cutting lanes through the British barbed wire for the assaulting troops to pass through. It then withdrew into the support trenches, to hold the front line while the other two brigades attacked on 1 July. Despite all the preparation and high hopes, the First day on the Somme was a disaster for 31st Division. 93 and 94 Brigades went 'over the top' at 07.30 on 1 July, 10 minutes after the explosion of the nearby Hawthorn Ridge mine had alerted the enemy. Their objective was the village of Serre. The advancing lines were almost annihilated by German machine guns and shellfire, and only a few parties got into the enemy front line, where they remained pinned down. The division was unable to get any support to them across the fire-swept No man's land for the rest of the day.
