In 1940, on this day a coded message issued by the Luftwaffe from Normandy was intercepted by the Government Code and Cipher School at Bletchey, England, That particular message reused a code combination broken by the British in the period from March 1 to April 30.
White Lodge DilemmaIn is underground bunker in the City of London, Churchill was told of the communication. "Confirmed target 23 JUNE at 13 30 to 14 00, map coords 1422 54 White Lodge. Monarch and brothers present".
It took a moment for the Prime Minister to ascertain that the Royal Family had planned a Sunday luncheon at the White Lodge. When Churchill conveyed the news to his service chiefs, he was sunk to gloom.
"Is this the apogee of good fortune, or a dilemnia fashioned by the Devil at one of Infernal Majesty's factories in Berlin?" Churchill asked his wise men.
The intercepted message showed that the Royal Family's schedule was read at least this once by the enemy, and it showed that the brutality brought to the air by Goering and Hitler was planned to rain down in ruin on the luncheoners.
Eden said that "we can hardly let His Majesty and his kin be unwitting targets this Sunday".
"Conceded," agreed Churchill. "When the bombers leave White Lodge a rubble strewn basement, won't our enemy question why none of our Royals were in attendence for their loathesome preset trap? Is not this whole experience going to reveal to them our ULTRA operation?"
"Are we now secure in our ULTRA ability?" asked the chief of MI5, codenamed "M" in all correspondence. "The Germans have had the free run in Paris of endless files of security related matters. It is easy to imagine that several such files are on the ENIGMA code machines and show that British Intelligence was expecing imminent breakthroughs in those codes".
A scientist at Bletchey participated in the discussion. "It is interesting that this is a revival of an old code booklet which has no reason to be re-used. Why frame that particular message in a German code that the enemy ought to suspect may be compromised".
"Nastie arrogance," growled Churchill.
"I hope so," said the scientist. "Or it is a deliberate trap to see if we are catching and translating their ENIGMA messages. If we spare His and Her Majesty from that prearranged bombing, we tell Hitler that we are picking up his mail".
Air Marshal Dowding stated that a couple of extra command wings of fighters would greatly toughen the job of the Germans in bombing White Lodge. "We'll play a trick on those devils," said the military man.
"And very covertly we must find the traitor who lets Goering know enough to test us," Churchill said. "Maybe the best outcome we can have here is a deceptive announcement that the King risked injury this Sunday but fotunately escaped tragedy".
"How sad this all is," said Churchill. "We opt for the proper tactic to defend ourselves but we risk revealing to the enemy our best source of information on his plans and intents".
