World War 2 Battle of Dunkirk code But if not?

It is an allusion to the Book of Daniel (Daniel 3:18), where Shadrach, Meshach, and Abednego tell the Babylonian King, Nebuchadnezzer, that they would rather die than worship a false god. The men at Dunkirk sent the message stating that should not they be saved, that they would still not worship the false god (Fascism in this instance) but would die in triumph knowing that their belief would eventually take the day.
