Many studies have covered aspects of military intelligence available to Britain and her allies during the Second World War. This distinguished book provides a succinct and authoritative survey of the vital role Ultra played in achieving final victory., When war began Britain was as ill-prepared in intelligence as armaments. Civilian scientists had discovered the principle of radar in the mid-1930s, but everything had to be learned from scratch in the heat of emergency. First signs of improvement came in mid-1941, when Ultra targeted naval vessels and bomber aircraft onto so many of Rommel's supply ships that the Africa Corps almost withered on the vine. From then on intelligence played an increasingly indispensable part in final victory. Ultra won the Battle of the Atlantic, driving U-boats back to coastal waters by June 1943. Ultra confirmed the whereabouts of the German tanks as Montgomery planned the breakthrough to Alamein. Only 'Bomber' Harris refused to give intelligence the credit it deserved; on the basis of new evidence this fascinating book strongly reinforces criticism this costly mistake.

This textbook is a product of William Bennett's work in developing and teaching a course on the physics of music at Yale University to a diverse audience of musicians and science students in the same class. The book is a culmination of over a decade of teaching the course and weaves together historical descriptions of the physical phenomena with the author's clear interpretations of the most important aspects of the science of music and musical instruments. Many of the historical examples are not found in any other textbook available on the market. As the co-inventor of the Helium-Neon laser, Prof. Bennett's knowledge of physics was world-class. As a professor at one of the most prestigious liberal-arts universities in the world, his appreciation for culture and humanities shines through. The book covers the basics of oscillations, waves and the analysis techniques necessary for understanding how musical instruments work. All types of stringed instruments, pipe organs, and the human voice are covered in this volume. A second volume covers the remaining families of musical instruments as well as selected other topics. Readers without a background in acoustics will enjoy learning the physics of the Science of Musical Sound from a preeminent scientist of the 20th century. Those well versed in acoustics will discover wonderful illustrations and photographs depicting familiar concepts in new and enlightening ways.

Military intelligence, grossly neglected during the interwar period, had by mid-1942 proved itself indispensable through information gathered from intercepted radio messages in the supposedly unbreakable German Enigma cipher. Ralph Bennett, who worked for four years at Bletchley Park as a senior producer of the intelligence (Ultra') derived from the Enigma decrypts, illustrates in this collection of reprinted essays some of the steps by which he and others developed the new type of information and in the process a candid glimpse of the workings of British intelligence both past and present.

This remains a much needed book. It offers a succinct and authoritative survey of military intelligence available to Britain and her allies during the Second World War.

When war began, Britain was as ill-prepared in intelligence as in armaments. Scientists had discovered the principle of radar in the mid-1930s but everything else had to be learned from scratch in the heat of emergency. Early signs of improvement came in mid-1941, when Ultra targeted naval vessels and bomber aircraft so successfully onto Rommel's supply ships that the Afrika Corps came close to inanition. From then on intelligence played an increasingly indispensable part in the ultimate victory. Ultra won the Battle of the Atlantic, driving the U-boats back to coastal waters by June 1943. Ultra confirmed the whereabouts of the German tanks as Montgomery planned the breakthrough at Alamein. Only 'Bomber' Harris refused to give intelligence the credit it deserved which, as this book makes clear, proved to be a costly mistake.

'This book has been needed for some years, both by general readers and by scholars. The author is ideally equipped to write it, and it could hardly be better done. . . His summary of the value and limitations of intelligence work in western Allied strategy will be of lasting value.' M.R. D. Foot

'Ralph Bennett's mastery of narrative and clarity of analysis are such that we can safely signal a new benchmark in intelligence books.' David Linton

'Bennett has done more than anyone else to throw light on the impact of Ultra on command decisions. . . Essential reading for any historian of intelligence.' David Stafford

'Ralph Bennett has a unique place in the history of wartime intelligence. . . Once an insider, thereafter a historian. . . his research approaches the ideal more closely than any previous study has done.' John Ferris, "Intelligence and National Security "
