Salinger's Work in World War II Army Intelligence
J.D. Salinger was part of the U.S. Army's Counter Intelligence Corps (CIC) on the ground in Europe during World War II. Salinger formed a strong bond with three other men in the CIC and they dubbed themselves the Four Musketeers. One of them took the only known photo of Salinger writing "The Catcher in the Rye" during his army service.
