their plans and movements, handing the Allies huge amounts of information, not all of which was used effectively. For example, Rommel's actions at Kasserine Pass were clearly foreshadowed in decrypted Enigma traffic, but the information was not properly appreciated by the Americans. After the war, Allied TICOM project teams found and detained a considerable number of German cryptographic personnel. Among the things learned was that German cryptographers, at least, understood very well that Enigma messages might be read; they knew Enigma was not unbreakable. They just found it impossible to imagine anyone going to the immense effort required. When Abwehr personnel who had worked on Fish cryptography and Russian traffic were interned at Rosenheim around May 1945, they were not at all surprised that Enigma had been broken, only that someone had mustered all the resources in time to actually do it. Admiral Dönitz had been advised that a cryptanalytic attack was the least likely of all security problems. After World War II Modern computers can be used to solve Enigma, using a variety of techniques. There have been projects to decrypt some remaining messages using distributed computing. Stefan Krah led an effort in Germany to decrypt three messages intercepted in 1942 by ; the messages were published by Ralph Erskine in a 1995 letter to Cryptologia. Two of these messages were cracked in 2006, and the final one was decrypted in 2013. As of January 2018, the Enigma@home project is working on Enigma M4 message P1030680, which was sent from U-534 on 1 May 1945. On 8 May 2020, to mark the 75th anniversary of VE Day, GCHQ released the last Enigma message to be decrypted by codebreakers at Bletchley Park. The message was sent at 07:35 on 7 May 1945 by a German radio operator in Cuxhaven and read: "British troops entered Cuxhaven at 14:00 on 6 May 1945 - all radio broadcast will cease with immediate effect - I wish you all again the best of luck." It was immediately followed by another message: "Closing down forever - all the best - goodbye." See also Cryptanalysis of the Lorenz cipher I.J.
