This site is a mock-up of the World War I intercept site in Souilly, France. The exhibit is based on two pictures of the original shack. Intercepting the enemy's radio communication was imperative for success during WWI. At the outbreak of war in August 1914, the German Army successfully used vital radio intercepts, enabling them to defeat the Russian 2nd Army in the Battle of Tannenberg. Soon all the major participants in World War I would go on to use more encompassing communications intelligence (COMINT) with varying degrees of success. Although signals intelligence was in its infancy, and radio was the new communications technology, the U.S. Army's Radio Intelligence Section used their newfound capabilities to "spy" on enemy conversation. Signals could be intercepted without being in close proximity to the transmitter or transmission lines and could provide vital information about enemy tactics and strategy.
