The plan: For one week, British guns would bombard German held trenches with heavy artillery. The British bombardment would destroy the German trenches and blast the German barbed wire to pieces. German troops would be shell shocked and surrender. At 7.30am the barrage would stop and British soldiers would walk in to no man's land. Some would carry heavy packs full of equipment to rebuild the German trenches as they captured them. When a suitable gap opened up, Cavalry would be used to gain ground.
