For the first time the story of the Navy and Marine Corps in the 1941-42 Philippine campaign is told in a single volume. Drawing on a rich collection of both U.S. and recently discovered Japanese sources as well as official records and wartime diaries, Gordon chronicles the Americans' desperate defense of the besieged islands. Gordon offers updated information about the campaign during which the Navy and Marines, fighting in what was largely an Army operation, performed some of their most unusual missions of the entire Pacific War. He also explains why the Navy's relationship with Gen. Douglas MacArthur became strained during this campaign, and remained so for the rest of the war. As a result of Gordon's extensive primary source research, Fighting for MacArthur presents the most complete account of the dramatic efforts by elements of the Navy and Marine Corps to support the U.S. Army's ill-fated defense of the Philippines.
