“We came across a lad from A company. He was ripped open from his shoulder to his waist by shrapnel and lying in a pool of blood. When we got to him, he said: ‘Shoot me’. He was beyond human help and, before we could draw a revolver, he was dead. And the final word he uttered was ‘Mother.’ I remember that lad in particular. It’s an image that has haunted me all my life, seared into my mind.”
