“One of them was about a British Soldier who had a clear shot at Hitler, but since Hitler was just a messenger, the soldier didn’t shoot.”
Hitler was a nobody back then, and didn’t even have his trademark mustache, so why would anyone remember seeing him? Doesn’t add up.
Hitler told a story about a Tommy letting him go when he was wounded, alone and headed for German lines. Between the wars he saw a painting of a famous British soldier, and claimed that was the fellow who let him go. It doesn’t appear the British soldier and Hitler’s unit ever faced each other, even if one supposes Hitler’s story was true .
From the article, it had nothing to do with the British Soldier knowing who Hitler was. He was just a German soldier to him.
It is foggy, but the article I linked has a lot of info.
