Pigeon enthusiasts are now calling for 40TW194 to be posthumously decorated with the Dickin Medal.
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.
Most likely, 40TW194 was destined for the top secret Bletchley Park, which was just 80 miles from Martin's home. Now a museum, Bletchley Park is where codebreakers worked around the clock to crack the Nazi's "unbreakable" Enigma code.
"The message Mr Martin found must be highly top secret. We have more than 30 messages from WWII carrier pigeons in our exhibition, but not one is in code," Colin Hill, the curator of Bletchley Park's "Pigeons at War" exhibition, said.
"We know it's an Allied Forces pigeon because of the red capsule it was carrying - but that's all we know," he added.
The message was sent to XO2 at 16:45 and contain 27 codes, each made up of five letters or numbers.
