In 1943, less than a year before D-Day, nearly three hundred American, British, and French soldiers—shadow warriors—parachuted deep behind enemy lines in France as part of the covert Operation Jedburgh. Working with the beleaguered French Resistance, the "Jeds" launched a stunningly effective guerrilla campaign against the Germans in preparation for the Normandy invasion. Colin Beavan, whose grandfather helped direct Operation Jedburgh for the Office of Strategic Services, draws on scores of interviews with the surviving Jeds and their families to tell the thrilling story of the rowdy daredevils who carried out America's first specialforces missions—forever changing the way Americans wage war.
