re: A seriously underrated aspect of D-Day and the Allied offensive in France

If you want to talk about a seriously underrated aspect of the D Day invasion, you need to familiarize yourself with Juan Pujol García, also known by his codename Garbo. He was a Spanish double agent, working for both the Nazis and the Allies. He wasn't actually a spy though and had zero training in intelligence or espionage. His entire network of subagents were mere inventions of his mind. He was so convincing though that the allies were able to use him and his "network" to convince the Germans that the D Day invasion was a decoy. The other underrated aspect of Garbo was that because the Allies had his original transmissions to the Germans each day, they had great insight into the set up of the German enigma code for the day. This allowed the allies to decode other German intelligence in real time.
