Collection (ca. 1936-1997) relates to the life and career of Arthur Greenville McIntyre; an Lieutenant Commander of the United States Navy who was a U.S. Naval Academy graduate (Class of 1941) and who served in the Pacific theater of World War II. McIntyre served on the submarine U.S.S. Grenadier until it was lost in April 1943 by Japanese bombing. As a result of the attack, he became a prisoner of war of the Japanese and was not released until September of 1945. The bulk of the collection is on McIntyre's naval career but there is also material containing his biographical information and information on his time as a prisoner of war. Of particular interest are documents that have information on the Japanese who ran the POW camps and who were tried in the war crimes trials that were held in Japan. The documents lists their names and the sentences they received as a result of those trials. The majority of the documents in the collection are in English but some are in Japanese and Spanish with no translation.
