“In June it took part in an elaborately planned action at Messines Ridge, in Belgian Flanders, which opened with the Allies detonating a million pounds of explosives next to the German trenches, instantly killing 10,000 enemy soldiers. The blast was heard in London and felt across southern England. In the fighting that ensued, Bill Alabaster led the parties carrying grenades, ammunition and water from the 45th Battalion headquarters to the troops at the front line, across open ground raked by artillery and machine-gun fire. Herring recommended him for the Military Medal. The 45th lost seven officers and 344 other ranks over four days of combat.”
