Espionage

Espionage means to spy. But, not just any spying. Spying on other countries' military forces, like that. There were many wars in the world. A few are: The Vietnam War, The American Revolutionary War, The Civil War, The Cold War and World Wars 1&2. There were many spies that espionaged the opponent's or enemy's side. They used secret codes also. If there was a person that you wanted to get a letter to, and your enemy's soldiers guard a section in front of the place you want to get it to, then they made use of secret codes. The Cold War wasn't exactly a war where you used weapons to defeat the enemy's team whoever it may be. It was a war where they passed cruel notes, and secret codes to each other. There was also a wall separating. It separated West Germany and East Germany. Ok, now bye!
