Fighting Spirit is an annotated translation of the memoirs of Imperial Japanese Army Major Yoshitaka Horie, co-edited by a USMC veteran of the Battle of Iwo Jima and an American academic who is a specialist on U.S.-Japan relations. Maj. Horie's book was first published in 1965, on the 20th anniversary of the battle. It was his desire to have it published in English, but he passed away in 2003 before seeing his dream realized. In addition to the 19 chapters of Horie's original work, the book includes an Editors' Preface, which provides biographical information on Maj. Horie and the context of the book, and two appendices of materials prepared by Maj. Horie shortly after the end of the war.
