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.
