As a second world war loomed, some Jewish parents sent their young sons away to uncertain futures in America, perhaps never to see them again. After the United States entered the war, these boys—now young men—returned to fight for their adopted homeland. Named for the Maryland fort where they trained, the Ritchie Boys were used to interrogate prisoners and gather tactical intelligence, a field in which they had no equals. Drawing on interviews, Bruce Henderson vividly re-creates the stories of these men, tracing their journeys from childhood through their feats during the war and their attempts to find their missing loved ones.
