I added the following pic in Italian codebreakers of WWII.
Also in Japanese
codebreakers of WWII I added ‘From
1943 onwards the Japanese could solve the Soviet diplomatic code used by the
embassies in Seoul, Dairen, and Hakodate for communications with Moscow and
Vladivostok’ under the ‘Japanese
Army agency’ paragraph and deleted the similar part from the naval agency. The
reports I have are from the Japanese army so it would seem that they were
responsible for this success.
