Espionage was the secret war that was happening during WWI. Countries had to establish intelligence agencies that would affect their countries war efforts in a positive way. Not only that but protecting important communication cables was a full time job. It was just as important for countries in WWI to gain intelligence information as it was to protect it.
On the front both sides relied on a network of cables and wireless links for
communication and intelligence gathering. The soldiers and spies on the
front maintained a web of trench and field telephone lines. This was a way to
obtain intelligence information and communicate with ones country back on the
home front. The Allied and central powers would attempt to damage each others networks, protect their own, try to obtain information from the opponent’s networks, and try to transmit false information through it in attempt to trick their opponents.
During WWI there was a noticeable expansion of the international telegraph network this was caused by the laying of submarine cables. Submarine cables comprised of many individual wires and where either under close supervision or government control. The single wires in the submarine cables had the capability to transmit multiple messages. The destruction or damage of an international telegraph station would cause a big disruption and take a long time to replace especially if it had to be transported overseas. This was why it was crucial to destroy an enemy’s telegraph station and protect your own at the same time.
Another way of intelligence gathering was through observation
balloons. Observation balloons were used in WWI for intelligence gathering and
artillery spotting. From 1914 to 1918 both the allies and Germany deployed
balloons a few miles behind the front lines. The observers had the advantage of
seeing enemy lines and communicating with the soldiers on the ground, often the
observers in the balloons would have to parachute to the ground when under
attack.
Espionage was a big part of World War I from the telegraph, to
phone tapping and even using human spies. Espionage was the key to countries
winning major battles that helped them in the war.
