The Role of Espionage in World War II

Spying was at the center of World War II in many ways, influencing the tactics of a country and outcomes of a battle in different theatres of war, European, Asian, and other. Military espionage surprised operations and got the reinforcement of important information on the enemy’s plans, movements, and technologies that would most times turn the tide of the fighting in favor of the Allies or the Axis.

The Allies undertook highly involved espionage procedures through Britain’s MI6 and the United States OSS. One good example is the success of the codebreakers who worked for Bletchley Park in decoding messages encrypted through the German Enigma machine. This achievement, together with Alan Turing and his team, enabled the Allies to transcode and decipher German communication, thus enabling them in their fight.

Covert collection of intelligence also formed part of disinformation. An important Allied strategy called Operation Fortitude was designed in order to mislead the German army concerning the real location of the D-Day on the Normandy landings. On the Axis side, spies were present in Allied operations, but their efforts were always met with very strong counters.

Other areas which were occupied had equal use of espionage by the resistance movements. Some of these secret societies collected and passed on information to the Allies; the enemies’ plans were undermined. CI in the Second World War presented how intelligence played a central role in today’s warfare, reemphasizing the fact that intelligence was much more than a strategic weapon in warfare.
