Double-agents in WWII

One of the most laughable yet daring double agents in history is Eddie Chapman. Nick named Zigzag later on in his life, did not work his way up from the ground. Instead, he was captured by the Germans for safe cracking, but offered them the chance for him to spy on the British army before he left. Ignoring his offer, the Nazis thought it was the last of him. But it was not long after that he was caught doing the same thing he had done in since the last time. Again, Chapman offered the Nazis for him to spy on the British, and this time, they accepted. 

In the years that follow, the Germans taught Eddie Chapman everything there needs to know as a spying agent. However, what they didn't know was that Eddie was working with the British army as well, M15. Eddie gave false information to the Germans, but not too much information as it could potentially paint him a false agent. He continued with this charade and was even decorated the medal of bravery by the Germans.

After the war, Eddie Chapman did the most hilarious thing a soldier could do after saving hundreds to thousands of lives. Chapman smuggled gold and ran a health spa, among other activities as well. It is unfortunate, but he died in 1997.
