This work is part of the diary that the now 94-year-old Abraham Felber kept during his service in World War II. It begins with January 7, 1941, and ends with December 31, 1945. Felber was a keen observer, and for much of the war it was his job to keep records for his unit. As the 1st Sergeant of Headquarters Battery, 11th Marines, Felber dealt with both officers and enlisted men, which exposed him to the perspectives and insights of both. Felber was also granted the privilege of taking photographs during the Guadalcanal and Cape Gloucester campaigns, some of which are published here for the first time. Felber’s accounts of his unit’s role in the combat at Guadalcanal and Cape Gloucester, his time at Guantanamo Bay, and other experiences are presented here as he recorded them.
