Front of a ‘Red’ message, intercepted from the General Operational Key for the German air force (codenamed ‘Red’ at BP). Bletchley Park first began to regularly decipher ‘Red’ network messages from 22 May 1940 – their first break into German Enigma. Towards the bottom of the page is a Bombe machine menu, written in red pencil. This indicates how a Bombe machine could be set up to try to find the settings used on the Enigma machine that encrypted this message.
Reverse of the same message. When deciphered, this message turned out to be an ‘abstimspruch’ or test message – the word underlined in red. Although this may seem frustrating, the term ‘abstimspruch’ could be used as a ‘crib’ – a guessed piece of message text that gave the Codebreakers a starting point to break the message encryption. This in turn could unlock a whole day’s worth of messages on an Enigma network.
Detail from the front of a message. ‘Red’ messages, sent by the German air force using their General Operational Key, were so named because Codebreaker Gordon Welchman used a red pencil to annotate them. Messages sent using other Enigma keys were marked with different coloured pencils. Later, when Bletchley Park ran out of colours, they named keys after plants, insects and birds.
Detail from the reverse of the same message. The message highlights a limitation of wartime communications, stating that a message failed to reach the intended recipient as they were travelling to Norway. Modern day electronic communications have overcome such problems.
Each Enigma message was preceded by a ‘preamble’. This contained the sender’s call sign, the time of transmission, the number of characters in the message and the indicator – a group of characters that helped indicate the Enigma message setting. This message was sent from call sign XFZ DE C at 16.25, it is 203 characters in length and the indicator is KXB GBY. The indicator only applies to this transmission and cannot be used to work out the many other Enigma settings needed to read the message.
The reverse of the message reports the movements of several individuals including Oberleutnant Konzack, Oberleutnant Woldmann, a Fighter Pilot, a Radio Operator and a Flight Mechanic.
The fronts of the message transcripts also record the time and date each message was transmitted, and intercepted at a British Y Station. This message was transmitted to Bletchley Park by teleprinter at 15.43 on 2 November 1944.
A report on the night activity of a German air force unit under the command of Unteroffizier Jaekel. The markings used by the Codebreakers to make sense of the message are clearly visible. Vertical lines are used to separate words, a curving line under words indicates a name, and numbers are written out in Arabic numerals below the text.
This page shows the second part of a longer message, which would have been sent in sections. Part 1 is described as a ‘dud’, or failure, on the top in pencil. It also doesn’t appear to have a printed preamble.
Information contained in Enigma messages was analysed to produce Ultra intelligence. Here a Codebreaker has scrawled notes concerning General Wilke, a German paratroop general to whom this message relates, at the bottom of the page.
