Here's Something

Found here, but I'd suggest you goto the beginning and read from 1939-43, as 44-45 are kinda' super depressing.

Uh, the line you will be looking for is in bold...

Thousands of carrier pigeons accompanied the troops to Normandy on D-day and brought back essential details to Allied Headquarters in a capsule tied to their legs. A special loft was erected at the secret code deciphering centre at Bletchley Park. Considered vermin by many, these pigeons, were first used as early as the year 1150 AD and played an important part in both world wars. News of Wellington's victory at Waterloo first came by pigeon post. Many of these birds were specially bred in Belgium prior to 1939. Often used as a distress signal from downed aircraft, a pigeon named 'Winkie' escaped from a bomber after coming down in the English Channel in 1943. It flew back 120 miles to its base at RAF Leuchers in Scotland in time for rescue boats to reach and save the crew of the stricken bomber. Winkie was awarded the Dickin Medal (the animal version of the Victoria Cross) the first pigeon to be awarded with the medallion. Many of these pigeons were dropped by specially designed parachutes to be picked up by members of the French resistance. They were soon on their way back to Britain with Important information. At this time the Germans were training Falcons to intercept the pigeons while in flight and many were killed this way. In all, thirty-two animal VCs were awarded to pigeons during WW11, also awarded were 18 dogs, 3 horses and one cat, a pet on HMS Amethyst. Instituted by Mrs Maria Dickin MBE in 1943, founder of the People's Dispensary for Sick Animals (PDSA) a British veterinary charity, the Dickin Medal was awarded to any animal, bird or dog, displaying conspicuous gallantry during war.

However awesome this factoid is, I do agree with the 3rd sentence 1st statement..."Considered vermin by many..." I am certainly one of the many.
