雙語暢銷書《艾倫圖靈傳》第6章:連接兩個世界(3)
The decrypts flooded in, at an average rate of 3000 a day, like a newspaper filled with nothing but concise, up-to-date news about the Atlantic operations.
Just as the flow began, in early December, the 'irreplaceable' Winn collapsed from 'total mental and physical exhaustion' and 'what was not of immediate operational importance had to be put on one side for later study and usually, before this could be undertaken ... the next crisis was upon us and the study had to be abandoned,' and so forth.
12月初，這種持續供應剛一開始，德國的絕密情報，反而英美軍方造成了信息過剩。不需要立即處理的信息，只能先暫時扔在一邊。But somehow the joint system managed to keep going, and in the new year became able once more to divert convoys away from known U-boats.
雙方的合作很成功，在新的一年裏，護航隊總是能夠避開U艇。
The result was that on the other side, they could not understand why their success in sinking Allied shipping had suddenly been reduced to the level of September 1941.
德國感到很困惑，他們無法明白，爲什麼他們擊沉記錄突然降到了1941年9月的水平。Indeed they were sure that U-boat positions were somehow known to the enemy.
實際上，他們非常肯定，敵人一定通過某種方法，得知了U艇的位置。But the head of the German naval intelligence service at Naval High Command adhered to the opinion that it would be impossible for the enemy to have deciphered the signals.
但是，德國海軍指揮部情報部門的領導堅持認爲，敵人不可能破譯通信。They continued to assume that there was a spy network operating in their bases in occupied France, although nothing could have been further from the truth.
他們始終認爲，肯定是法國的某個基地遇到了間諜行動。這跟實際情況相差太遠了。There were in fact many other factors involved besides cryptanalysis—the provision of escorts and aircraft patrols, the development of radar and of counter-radar measures, and the fearsome weather of this fourth winter of the war.
這一系列巨大的成功，除了密碼分析的功勞，還有很多其它方面的因素——護航飛機的支援，雷達和反雷達技術的進步，以及第四個冬天的惡劣天氣。But the crucial change was that Allied authorities once more knew where the U-boats were.
但是，最具決定性的因素，就是盟軍又能捕捉U艇的方位了。
