I just read that a Tommy captured a Jerry and the Jerry asked the Tommy to write his mother and advised that he was captured, in good condition and a PoW. The Tommy did and the Jerry's mother wrote back thanking him for the news of her son (she hadn't been advised and was understandably worried). She wrote back and thanked the British soldier for the letter and even included a photo of the son. How did the letters go through? Switzerland? Sweden? I'm sure everybody (officer's soldier, German intelligence or Gestapo) read it before it reached her.
