U.S. Navy Commander I.J. Galantin, who retired as an Admiral, refers several times to Magic in his 1988 book about his Pacific theater war patrols as captain of the U.S. submarine . However, Galantin refers to Magic as "Ultra" which was actually the name given to the breaking of the German code. Upon receiving one message from Pacific Fleet command, directing him off normal station to intercept Japanese vessels due to a Magic message, Galantin writes. "I had written my night orders carefully. I made no reference to Ultra and stressed only the need to be very alert for targets in this fruitful area". Galantin had previously mentioned in his book that all submarine captains were aware of "Ultra" (Magic).
