Strategic And Operational Deception In The Second World War

First Published in 1987. New information obtained from the declassification of Ultra intercepts and other Second World War documents as well as from recent scholarly research has credited Allied deception operations with an even more important contribution to winning the war than was previously supposed. Yet deception is only one factor in the achievement of victory; it cannot guarantee success. It must be fully understood and exploited by the highest levels of command. Most histories of deception operations during the Second World War have focused on those that were successful. Instances in which deception operations failed to achieve their objectives are discussed by John Campbell, who describes an early attempt to convince the Germans that the Allies intended to invade at Pas de Calais in the summer of 1943, and by Katherine Herbig, who gives the first detailed description of US deception operations in the Pacific. Klaus-Jurgen Moiier questions the actual effectiveness of deception operations against the Germans. He argues that many successes attributed to the Allies' use of deception were in fact achieved by independent considerations on the German side. Professor Moiier builds a particularly strong case in challenging the success of Operation Fortitude North, in which the Allies tried to divert German troops to Norway before invading Normandy. Although very little is known of Soviet deception operations on the Eastern Front, it must be remembered that they were conducted on a much larger scale than those of either the British in Europe or the Americans in the Pacific. Colonel David Glantz's account of Soviet deception and covert activities offers a version of the historiography of the war between the USSR and Germany which may explain some of the monumental German failures. Tom Cubbage not only contributes a synthesis of the primary and secondary sources available on the deception operations preceding Overlord, but also reviews the so-called Hesketh Report - Fortitude: A History of Strategic Decep­tion in North Western Europe April 1943 to May 1945, Colonel Roger Hesketh's official report on Allied deception operations against the Germans in north-west Europe which was declassified in 1976, yet remains unpublished. It indicates that Professor Muller's suspicions that the Allies over-estimated the impact of Forti­tude are unfounded. Edited and with a comprehensive introduction by Michael Handel, these important and original studies put the entire deception effort during the Second World War into a more balanced and accurate perspective.

Volume 5 of the Official History of Intelligence in the Second World War, Strategic Deception, brings the series to an end. Strategic deception depends for its success on the availability of good security and good intelligence. The first three volumes of the series described the intelligence channels that gave the Allies their incomparable insight into enemy capabilities and intentions.

In World War II, the Allies employed unprecedented methods and practiced the most successful military deception ever seen, meticulously feeding misinformation to Axis intelligence to lead Axis commanders into erroneous action. Thaddeus Holt's elegantly written and comprehensive book is the first to tell the full story behind these operations. Exactly how the Allies engaged in strategic deception has remained secret for decades. Now, with the help of newly declassified material, Holt reveals this secret to the world in a riveting work of historical scholarship. Once the Americans joined the war in 1941, they had much to learn from their British counterparts, who had been honing their deception skills for years. As the war progressed, the British took charge of misinformation efforts in the European theater, while the Americans focused on the Pacific. The Deceivers takes readers from the early British achievements in the Middle East and Europe at the beginning of the war to the massive Allied success of D-Day, American victory in the Pacific theater, and the war's culmination on the brink of an invasion of Japan. Colonel John Bevan, who managed British deception operations from London, described the three essentials to strategic deception as good plans, double agents, and codebreaking, and The Deceivers covers each of these aspects in minute detail. Holt brings to life the little-known men, British and American, who ran Allied deception, such as Bevan, Dudley Clarke, Peter Fleming, Douglas Fairbanks, Jr., and Newman Smith. He tracks the development of deception techniques and tells the hitherto unknown story of double agent management and other deception through the American FBI and Joint Security Control. Full of fascinating sources and astounding revelations, The Deceivers is an indispensable volume and an unparalleled contribution to World War II literature.

Second World War history offers the military strategist a cornucopia of lessons learned on how to apply the art of military deception. This paper analyzed six Allied deception operations to identify the fundamental reasons why Allied deception efforts were the most successful in history. The six deception operations reviewed were Barclay, Cockade, and Bodyguard as well as the Soviet deception operations at Stalingrad, Kursk, and White Russia. A critical analysis of these six operations identified seven major factors that made Allied deception efforts extremely effective. These seven factors were that the Allies controlled all key channels of information, had great intelligence "feedback" on their deception operations, had high-level and centralized control over deception planning, practiced sound deception techniques, subordinated deception to strategic and operational objectives, maintained adequate secrecy, and provided sufficient time for deception execution. These factors are relevant for today's operations and should be imbedded within US doctrine.

The first book to draw on the official British papers containing deception secrets taht were classified until 1978. Tells the fascinating story of brilliant and sometimes ingenious ploys, and also reveals the many pathetic and sometimes laughable failures of deception strategy.

These factors are relevant for today's operations and should be imbedded within U.S. doctrine. This study then examined Joint Publication 3-58, Joint Doctrine for Military Deception, and determined it could better incorporate the lessons learned from World War II. Current joint doctrine could be improved by underscoring the contribution that deception provides to surprise, the importance of integrating deception within all three levels of war, and the importance of exploiting an adversary's preexisting beliefs when creating a deception story. Applying these World War II lessons will bolster U.S. deception capabilities.
