WWII espionage

World War II espionage involved secret gathering of intelligence by both Axis and Allied powers to gain strategic advantages. Spies used covert methods, coded messages, and disguises to collect information on military plans, troop movements, and technology. Organizations like the Allies' OSS (Office of Strategic Services) and Axis intelligence agencies operated worldwide. Espionage efforts included double agents, clandestine radio transmissions, and clandestine infiltrations into enemy territories. The intelligence gathered influenced key decisions, such as D-Day and overlapping efforts to disrupt enemy operations. These covert activities played a critical role in shaping the war’s outcomes, highlighting the importance of information warfare during the conflict.
