Delivering Enigma, the famous coding machine used by Germany during WW2
On 16th August 1939, a Polish constructed Enigma machine was delivered to General Stewart Menzies at Victoria Station in London. The Enigma machine was a gift to the British by The Cypher Bureau in Warsaw, following a successful meeting between The Cypher Bureau’s British and French counterparts on 26th July 1939. They also supplied the French with an Enigma machine. The Cypher Bureau had been successfully reading Enigma messages since 1932 following success by one of their number, Marian Rejewski in breaking the code. Marian Rejewski used mathematics in the form of a theory of permutations, inspired guesswork and material obtained by the French through Captain Gustav Bertrand to successfully break the code. Rejewski was then able to prepare plans for the construction on an Enigma machine, then with these plans AVA electronics factory in Warsaw produced their own machines for use by The Cypher Bureau. The Enigma machine destined for Britain travelled by diplomatic parcel to Paris and was then escorted by a Polish secret agent and Captain Bertrand to the coast. There it was smuggled across the channel in the baggage of an actor. Once on British shores the Enigma machine was recovered by its escorts and delivered to Victoria and the hands of General Stewart Menzies. He took the machine to Bletchley Park where the British codebreakers awaited its arrival with excitement.
