Used widely within the German Kriegsmarine and during WWII, these Codebooks were used aboard U-Boats and surface vessels as well as their shore bases. Common phrases can be substituted by number or letter codes and transmitted via Morse Code. That would give away the position of the vessel as the signal was triangulated and there were captured Codebooks being kept up to date at Bletchley Park. This Codebook contains handwritten references to the 'Rugard' - a steamship that was requisitioned by the Kriegsmarine and used to transport troops. The Rugard survived an attack by Russian torpedo boats, reputedly the last European Naval engagement of WWII.
