"Magic" Background of Pearl Harbor. Volume 5.

摘要

This volume contains 1941 Japanese military attache messages which were processed by American communications intelligence in 1945 and which supplement the 1941 messages in the first four volumes. These supplementary messages are arranged in two groups, like the arrangement in the first volume of the series. Two special studies are included regarding the "Winds" and "Stop" code messages. Additional Japanese messages of interest have been located recently and are included in Volume V. A summary was made, originally, of all of Parts A of all Volumes. This material is limited to the Hull-Nomura conversations. Finally, an index is included in Volume V which covers all the Volumes.
