Bletchley Park: Britain's wartime intelligence factory
It certainly wasn't the case that Turing alone cracked Enigma, any more than there was a single Enigma to be cracked.
And in any case, breaking an Enigma 'user group' was only the first stage. It enabled messages to be read, but what did the messages mean? The men and women of Bletchley Park could only find out by painstakingly synthesising and analysing thousands of decoded messages. This in turn meant that they had to develop a complex data management operation, mainly based on cross-referenced card indexes that were sometimes filed in shoeboxes. It also demanded that they created an intelligence assessment function, so that they could produce something useable to the Allies' military commanders.
Also good to see a good man get the credit he is due:
Winston Churchill and the Secret World
Understanding intelligence
Britian's secret weapon in the war against Hitler
Intelligence Stovepipes: They're a feature, not a bug
You can't expect much history in "historical dramas" when SJWs are in charge
It was the task of handling huge volumes of Enigma decrypts so that solid military intelligence could be produced that made Gordon Welchman a key figure at Bletchley Park. A Cambridge mathematician, like his more famous colleague Alan Turing, Welchman devised the system that was to process thousands of messages each day - from interception through to decryption, translation and analysis.
