The idea that you go off shooting prisoners, or anyone else is not on, and quite honestly... far fetched. In "A Private in The Guards" by Stephen Graham about the Scots Guards in The Great War when doing Lewis Gun training at Caterham, his Instructors tell him, "If the Germans try to surrender FORGET TO TAKE YOUR FINGER OFF THE TRIGGER!" There are many many instances from WW1 & WW2 or British troops shooting prisoners either whilst in the act of surrenedering or shortly after. Australians in WW1 had a trick of putting grenades in Germans pockets and telling them to run for it then laughing as they blew up.(Don't ask me where I read that, it was afew years ago.) I know of a WW2 4th Wilts soldier being told at gunpoint by some British soldiers to leave a wounded German alone he just come across as they wanted to sort him out. From Private Young's War Geoff Young 4th Wilts, 43rd Wessex. When I arrived yet another German paratrooper appeared, coming down some stairs on the outside of a house. I was getting used to these chance encounters but I think this time the German was more shocked than I was. He had ben slightly wounded and had his weapon slung round his neck. I beckoned him to me. He came over and immediately surrendered. Unlike the previous prisoner he could speak quiet good English. Then, unbelievingly, as I was speaking two shots rang outand the poor chap fell to the ground, shot in the stomach. l looked up and spotted two English soldiers from another regiment standing there, "Bloody hell" I said "you've shot a prisoner." I knelt down and applied two field dressings to try and stem the bleeding. As I was doing so I felt a tommy gun muzzle being pressed against the back of my neck, hard against the painful spot where I had been shot a few months earlier. A voice said "Bloody well help him and you're a dead man." My mind was in a whirl, I couldn't believe this was happening, I was furious. But then luckily, Capt Hamilton the MO suddenly appeared and as I looked up I saw a Sergeant, also from the other regiment , and the two men running away. Capt Hamilton looked at the wound and told me that there was little chance of saving him. As I went back to the poor unfortunate fellow he held out his hand and said, "Tommy, danke schon- for you the Iron Cross." These touching words, from a soldier who, until fifteen minutes earlier had been my enemy, left me with a mixture of both pride and sadness. Although he was a dying man his words lifted the anger in me and I momentarily forgot about the Sergeant and what he and his men had done. After all one had to wonder what had made them react in that way. Perhaps they had witnessed something similar against a comrade of theirs. It was wrong, sure, but I decided not to pursue the matter. A Grenadier Guard Veteran of WW1 also told me they always shot captured German snipers. I suppose these are instances DURING combat which are slightly different to shooting prisoners behind the Lines.
