The British Army entrusted its secrets to birdbrains

Disruption on the line

Communication was a major challenge for the British Army during the First World War (1914-18). Human runners and messenger dogs were vulnerable to enemy fire, and telephone lines could be destroyed in shell blasts.

Radio communication was still in its infancy. Early wireless sets were bulky, immobile and unreliable, and their messages were easily intercepted. It was only in 1917 that reliable sets became widely available for use in the trenches.

Pigeon power

Pigeons were found to be the most reliable way of sending coded messages from the front. With a maximum speed of 60 miles per hour, the birds could quickly fly up and out of range of sniper fire.

However, this form of communication was not without its own drawbacks. Pigeons could not be used after dark and they were also susceptible to gas. Casualties were fairly high, with around 10 per cent of the birds employed during the Battle of Messines (1917) falling foul of the enemy.

A bird in the hand

In 1918, the Army issued an official pamphlet called 'Carrier Pigeons in War'. It contained guidelines for soldiers on how to care for the birds and how best to use them to send messages.

A fully fledged service

The Army continued to use messenger pigeons in the Second World War, even sending them across the Channel to carry messages back to Britain on D-Day in June 1944.

Right up until 1950, the British Armed Forces paid civilian pigeon fanciers to maintain 100 birds for their use.

Some military groups still use pigeons today. In 2016, it was reported that Islamic State fighters were using the birds to carry messages.
