The first bombe was named "Victory". It was installed in "Hut 1" at Bletchley Park on 18 March 1940. It was based on Turing's original design and so lacked a diagonal board. On 26 April 1940, captured a German trawler ("Schiff 26", the "Polares") flying a Dutch flag; included in the capture were some Enigma keys for 23 to 26 April. Bletchley retrospectively attacked some messages sent during this period using the captured material and an ingenious Bombe menu where the Enigma fast rotors were all in the same position. In May and June 1940, Bletchley succeeded in breaking six days of naval traffic, 22–27 April 1940. Those messages were the first breaks of "Kriegsmarine" messages of the war, "though this success expanded Naval Section's knowledge of the Kriegsmarines's signals organization, it neither affected naval operations nor made further naval Enigma solutions possible." The second bombe, named ""Agnus dei"", later shortened to "Agnes", or "Aggie", was equipped with Welchman's diagonal board, and was installed on 8 August 1940; "Victory" was later returned to Letchworth to have a diagonal board fitted. The bombes were later moved from "Hut 1" to "Hut 11". The bombe was referred to by Group Captain Winterbotham as a "Bronze Goddess" because of its colour. The devices were more prosaically described by operators as being "like great big metal bookcases".
