Frank's POW Diaries
Frank wrote to Eileen every day during his time as a Prisoner of War. These letters were written in the form of a diary detailing his three-and-a-half years in captivity; he sent all 228 pages of them to Eileen as soon as he was released. The diary describes his time in Changi (February 1942 – May 1943), including the Selarang Barracks incident, his journey to Japan (May 1943 – June 1943) and his period of captivity in Hokkaido, the northern island of Japan (June 1943 – September 1945).
