Historians believe the bird was dispatched from Nazi-occupied France on June 6 1944, during the D-Day invasions.
Because of Churchill's radio blackout, homing pigeons were taken on the D-Day invasion and released by Allied Forces to inform military generals back on English shores how the operation was going.
The military pigeons were dropped behind enemy lines from bombers, whereupon resistance fighters picked them up, before releasing them homeward bound with top secret messages.
The brave birds played a very active role in World War II (the RAF trained 250,000 birds, forming the National Pigeon Service) and, between 1943 and 1949, 32 were awarded the Dickin Medal, Britain's highest possible decoration for valor given to animals.
The British spy pigeon either got lost, disorientated in bad weather, or was simply exhausted after flying for hundreds of miles. Experts speculate the bird might have attempted to rest on an open chimney, but was overcome by fumes from a fire below and he died.
It is possible the pigeon was destined for the top secret Bletchley Park, which was just 80 miles from Mr. Martin's home. Now a museum, Bletchley Park is where codebreakers worked around the clock to crack the Nazi's "unbreakable" Enigma code.
