Top Secret Ultra by Peter Calvocoressi - 1980: An Insider's Account of How British Intelligence Monitored and Broke the Nazi Top-Secret Codes

One of the classic descriptions of efforts at Bletchley to crack the German ciphers. Calvocoressi was one of the officers in charge of the ULTRA program. He writes beautifully. A number of later accounts rely in part on his, so those familiar with the story of ULTRA will recognize the details. There is not a lot by way of crypto, early comp-sci, or technical detail, which really is the unique achievement of the ULTRA decrypts. But it is an engaging story of the magnificent efforts of dedicated men and women and of the immense challenges they overcame.
