雙語暢銷書《艾倫圖靈傳》第5章:解謎接力賽(94)
The Munchen was found and taken on 7 May 1941 and it was with the settings thus obtained that they became able to read the June traffic 'practically currently'.
At last, they had a command of the day to day tactics.
終於，他們可以毫無滯後地掌握德國的當日戰術了。The July settings were captured from another of the weather-reporting trawlers, the Lauenburg, on 28 June.
6月28日，他們又繳獲了另外一艘氣象船勞恩堡號，從而得到了7月的設定。
Meanwhile on 9 May, an accidental, but brilliantly conducted operation had taken place.
與此同時，5月9日發生了一個意外，但最終卻出色地控制了，A convoy escort detected and disabled the U-110 which had attacked the convoy.
一艘護航船發現並擊毀了一艘想要攻擊它的U-110潛艇。In a split-second manoeuvre on the high seas, they boarded the U-boat and took intact its cipher material.
在極短的時間內，公海上進行緊急行動，他們登上潛艇，並且完整無缺地帶走了所有密碼資料。The lessons of 1940 had been learnt.
他們吸取了1940年的教訓。The material filled some outstanding gaps, for it included 'the code-book used by the U-boats when making short-signal sighting reports', and 'the special settings used in the Navy for "officer-only” signals'.
這些資料回答了一些尚未解決的問題，包括潛艇傳送偵察報告時使用的密碼手冊，以及海軍軍官專用的特殊設定。These Offizierte signals were doubly enciphered for extra security within the U-boat itself.
這些高級信號會在潛艇內進行雙重加密。From the Hut 8 point of view, these were signals which, even after the day's settings had been found and the decryption process applied, remained gibberish while the other messages became German.
對8號營房來說，即使解出這些信號的當日設定，並且執行解碼程序，得到的結果仍然是雜亂的。It required a second stage of attack to recover these, the innermost secrets of the U-boat operations.
這些需要雙重破解，才能得到最隱祕的潛艇行動機密，Now they had what they needed to do it.
而現在他們已經有條件來做這件事了。
