Used widely within the German Kriegsmarine and during WWII, these Codebooks were used aboard submersible boats to communicate with surface vessels and their shore bases. Common phrases can be substituted by a series of number or letter codes which were then transmitted via Morse Code. The present codebook was used aboard an S-212 Schnellboot, a fast attack craft with torpedo-firing capabilities referred to by Western Allies as an E-boat. The accompanying Marineliste is attached to the rest of the book with string, and would have been replaced with updated codes each year from 1940 onwards. The Allies were eventually able to locate E-boats by triangulating their signals, aided by numerous captured codebooks of this kind that would have been studied and used at Bletchley Park.
