The German Naval Radio Monitoring Service of World War II is still clouded in deep mystery. The few attempts to document the subject have disappeared, been difficult to acquire, or lacked clarity. With this book, noted German naval historian Jak P. Mallmann-Showell fills the void by presenting highpoints of the service"s interception, decoding, and intelligence activities. Drawing on documentation and memoirs from archives in Germany and England, the author covers the growth of "B-Dienst" and the integral part daily intelligence played in the thrust and parry of naval battles. The entertaining narrative format pieces together intercepted scraps of information on ship movements to provide a unique behind-the-scenes perspective that will be appreciated for its fresh insights on this long-neglected aspect of World War II. 172 pages. 160 illustrations. Hardcover. 8 x 10 inches.
