雙語暢銷書《艾倫圖靈傳》第5章:解謎接力賽(137)

Germany declared war on the United States on 11 December 1941, four days after the attack on Pearl Harbor.

1941年12月11日，珍珠港事件四天後，德國向美國宣戰。

'So we had won after All!... England would live, Britain would live; the Commonwealth of Nations and the Empire would live...', reflected Churchill.

丘吉爾的反應是："我們終將成功！……英格蘭必勝，不列顛必勝，英聯邦和英帝國必勝……"

But the first effects were disastrous for Britain.

但是，第一個影響對英國來說是災難性的。

The Pacific drew off the American naval vessels which had protected the convoys.

美國海軍抽調一部分力量到太平洋，無力再應對英國的護航問題了，

And it proved to be an even tougher job selling intelligence to the US Navy than it had been in the British Admiralty.

而且，與美國的情報交流非常有障礙。

Naval Enigma information had indicated the operation of fifteen U-boats off the American coast at the declaration of war, but the warning had been spurned, and no precautions taken.

在宣戰發生時，海軍謎機的破譯表明，有15艘U型潛艇正在美國海岸行動，但美軍對此不屑一顧。

Enormous shipping losses marked an unhappy start to the Grand Alliance.

大量的船隻損失，使同盟的笑容開始消失。

Then on 1 February 1942, a far greater blow was dealt.

接着在1942年2月1日，又發生了更大的災難。

The U-boats switched over on to a new Enigma system.

U型潛艇轉而用了新的謎機系統。

The Bombes failed to deliver their prophecies.

炸彈機無法成功破解它們。

There was no more ULTRA.

沒有比這更糟糕的事了。

The black-out of February 1942 meant that the U-boat Enigma analysis had to begin all over again, with the past two years serving as warming-up practice.

1942年2月的中斷意味着，潛艇謎機的分析工作必須重頭再來了，過去兩年都只能算熱身。
