Special operations - in this context, commando or guerilla activities - conducted by the U.S. Army in World War II have been the subject of a good many thrilling adventure stories but little sober, historical analysis. Only a handful of works have examined the critical issues underlying special operations, and the Army's historical series on World War II treats the subject only in passing. Yet special operations had a significant role that should not be ignored. Ranger units captured positions critical to the success of amphibious landings in the Mediterranean, France, and the Philippines. Partisans advised by American military personnel provided essential intelligence to American forces and harassed enemy troops in support of American operations in Italy, France, the Philippines, and Burma. As special operations forces grow in importance within the U.S. Army, we need to look at our experience with such activities in World War II. I recommend this study as an overview for Army leaders and other interested parties of an important, but often misunderstood subject. It fills a gap in the Army's history of World War II and honors individuals whose efforts, frequently unsung, nevertheless made a major contribution to the American and Allied victory in that war. Harold W. Nelson Brigadier General, United States Army Chief of Military History

The array of new technologies that came on the scene in the early 20th century resulted in widely varied new forms of military special operations once civilization embarked on its greatest war. Suddenly, fighting men could be delivered by parachute, submarine, glider, jeeps, and fast amphibious craft deep into enemy territory to perform special tasks; yet others would continue to perform missions the same as their ancestors in previous wars—on foot using stealth, endurance and patience. This work contains discussions of the employment of various special purpose, special mission organizations during World War II. These units operated in Allied and Axis countries and in various theaters of war including Europe, North Africa, the Pacific, Asia, and the continental United States. Representing every major combatant, the operations include various kinds of raids, intelligence gathering missions, support to partisan/guerrilla groups, prisoner rescues, direct-action missions, and at least two where the object was simply to steal something. Some missions would have been officially denied if the operations had been caught in the act. The book is divided into two sections: Behind Enemy Lines and Behind Friendly Lines, to demonstrate that special-purpose organizations can be employed wherever needed, even in areas controlled by military units of their own or allied countries. Many of the units described run the gamut of special mission types, from commando to parachute units, reconnaissance to sabotage units, and partisan training units as well as those with combined missions. Many of the operations described in this book continue to serve as templates for modern Special Operations missions, while still others—the first attempts of their kind—continue to serve as examples of what not to try under the circumstances. Michael F. Dilley served for 20 years in the U.S. Army’s Military Intelligence branch. After retiring from the Army, the author served for about ten years as an employee of the Department of Defense, then as a contractor for various U.S. Government agencies in several fields for 15 years. Author of several books and many articles, a number of these chapters are based on his previous writings for the legendary Behind the Lines magazine.

A brief history of secret British and American World War II organizations, their training, tools, successes, and their legacy. Winston Churchill famously instructed the head of the Special Operations Executive to “Set Europe ablaze!” Agents of both the British Special Operations Executive and the American Office of Strategic Services underwent rigorous training before making their way, undetected, into occupied Europe to do just that. Working alone or in small cells, often cooperating with local resistance groups, agents undertook missions behind enemy lines involving sabotage, subversion, organizing resistance groups and intelligence-gathering. SOE’s first notable success was the destruction of a power station in France, stopping work at a vital U-boat base. Later operations included the assassination of Himmler’s deputy Reinhard Heyrich and ending the Nazi atomic bomb program by destroying the heavy water plant at Vemork, Norway. OSS operatives established anti-Nazi resistance groups across Europe, and managed to smuggle operatives into Nazi Germany, including running one of the war’s most important spies, German diplomat Fritz Kolbe. All missions were incredibly dangerous and many agents were captured, tortured, and ultimately killed—the life expectancy of an SOE wireless operator in occupied France was just six weeks. In this short history, historian James Stejskal examines why these agencies were established, the training regime and ingenious tools developed to enable agents to undertake their missions, their operational successes, and their legacy.

Illustrated with 11 maps and 35 Illustrations From the plains of Europe to the jungles of the Pacific, the U.S. Army in World War II employed a variety of commando and guerrilla operations to harass the Axis armies, gather intelligence, and support the more conventional Allied military efforts. During the Allied invasion of northern France on D-day, elite American infantry scaled the sheer cliffs of the Normandy coast, while smaller combat teams and partisans struck deep behind German lines, attacking enemy troop concentrations and disrupting their communications. On the other side of the globe, U.S. soldiers led guerrillas against Japanese patrols in the jungles of the Philippines and pushed through uncharted paths in the rugged mountains of northern Burma to strike at the enemy rear. Special operations such as these provided some of the most stirring adventure stories of the war, with innumerable legends growing from the exploits of Darby’s and Rudder’s Rangers, Merrill’s Marauders, the Jedburghs, the guerrillas of the Philippines, and the Kachins of northern Burma. Despite the public and historical attention paid to the exploits of American special operations forces in World War II, their significance remains a matter of dispute. Both during and after the conflict, many officers argued that such endeavors contributed little in a war won primarily by conventional combat units. They perceived little, if any, place for such units in official Army doctrine. Yet others have contended that a broader, more intelligent use of special operations would have hastened the triumph of Allied arms during World War II. In their eyes, the experience gained by the U.S. Army in the field during the war was important and foreshadowed the shape of future military operations.

James D. Kiras shows how a number of different special operations, in conjunction with more conventional military actions, achieve and sustain strategic effect(s) over time. In particular, he argues that the root of effective special operations lies in understanding the relationship existing between moral and material attrition at the strategic level. He also presents a theoretical framework for understanding how special operations achieve strategic effects using a unique synthesis of strategic theory and case studies. This study shows how the key to understanding how special operations reside in the concept of strategic attrition and in the moral and material nature of strategy. It also highlights major figures such as Carl von Clausewitz, Hans Delbrück, and Mao Zedong, who understood these complexities and were experts in eroding an enemy’s will to fight. These and other examples provide a superb explanation of the complexities of modern strategy and the place of special operations in a war of attrition. This book will be of great interest to all students and scholars with an interest in special forces and of strategic and military studies in general.

In the nearly seven decades following World War II, the heroes of the Allied Forces have been rendered ageless through portrayals transforming their overseas triumphs into household tales. Books, films, and video games have reiterated the stories of such famed American units as Merrill’s Marauders and Darby’s Rangers. Some of World War II’s most important missions, however, were also the most secretive: they have only recently been declassified by the U.S. government. Now, for the first time, a single volume describes many of them in detail. In Shadow Warriors, military historian and retired U.S. Marine Dick Camp illuminates the untold history of American special operations units in World War II. The book’s action-packed narrative, rooted in a time before organizations like the CIA even existed, describes the adventures of those who paved the way for the special operations forces we know so well today—the U.S. Navy SEALs, U.S. Army Special Forces, and U.S. Marine Corps Special Operations Command (MARSOC). Split into two parts covering the war’s European and Pacific theaters, it features elaborate spy networks, covert parachutists, island assaults, amphibious raids, and the occasional catastrophic mission failure. Bolstered by an in-person interview with World War II veteran Sgt. Jack Risler (U.S. Marines Operation Union II) and a collection of rare black-and-white period photographs, Shadow Warriors is not only a gripping account of top-secret exploits: it is an homage to some of the brilliant, courageous, and previously unacknowledged heroes of World War II.
