The period from February 1 to April 13, 1942 was what was published. According to Morton, as to the preservation of the diary, “When he was captured it was tied between his legs, beneath his groins; later it was kept in different places and when he could get advance information on a “shake-down” inspection it would be in the pocket of a recently washed shirt on the clothes line, in full view of the searchers!”
