And who broke the 'unbreakable' German Enigma code ?

This guy?

"Five weeks before the outbreak of World War II, on 25 July 1939, in
Warsaw, the Polish Cipher Bureau revealed its Enigma-decryption
techniques and equipment to representatives of French and British
military intelligence, which had been unable to make any headway
against Enigma. This Polish intelligence-and-technology transfer would
give the Allies an unprecedented advantage (Ultra) in their ultimately
victorious prosecution of World War II."

Clearly not immediately relevant since it was much later that the German
Enigma code was broken.

How much did he contribute to this ....

Colossus had nothing whatsoever to do with Enigma decryption. It was
developed to assist decryption of the Lorenz cipher machine, a 5-bit
teletype machine incorporating the modulo-2 addition of a pseudo-random
stream. Used for high-level communications. To quote Tony Sale;
"Fortunately, it was more pseudo than random".

The machines used for finding the Enigma wheel settings were purely
electromechanical. They were called Bombes. One of those has been
replicated, too.

Eeyore is so rah-rah British he has to make up accomplishments.
Serious inferiority complex. Poor fact checking.

Very much like you.

Be a jerk. Or post some electronics. Take your pick.
