 The 28th's first major action came during the Battle of Pozières in late July and early August when they took part in two attacks.During the first attack, the 28th suffered heavily when they were committed to a night-time attack on the heights that got held up in heavy wire entanglements that the preparatory bombardment had failed to destroy; the battalion's losses were the heaviest in the 7th Brigade, amounting to 10 officers and 360 other ranks.A follow up attack was undertaken on 4 August, which proved more successful, eventually securing the objective.
