Veterans have returned to the famous codebreaking station at Bletchley Park
to help launch a new fundraising effort.
It was where top secret German messages were intercepted, helping to shorten the Second World War.
Over 80 veterans were welcomed back to the site. Aged between 89 and 102, they all worked at Bletchley during the conflict, in the effort to crack the codes produced by the Germans' Enigma machine.
