Communications: A variety of methods were used including semaphore (holding flags in set positions to form a message), signal lamps (only worked one way or the enemy would see the message) and carrier pigeons (as in this example being released from a tank). The principal form used was the field telephone with wires run down the sides of trenches and later set below ground to avoid them being cut by exploding shells. However, they took time to lay down and connect up so were no good for a moving attacking force.

Wireless telegraphy was used by ships and aircraft throughout the war but this form of communication was still in its early days and the British commanders were reluctant to use it as there was no guarantee that the radio frequency was secure. In fact, British intelligence and signals corps spent most of the war listening in to enemy transmissions. They crucially intercepted the 1917 message in which the Germans promised Mexico that it could have back all the territory it had lost to the United States if it would join them against the Americans. This ‘Zimmerman’telegram so enraged the United States that they finally declared war on Germany.
