Another purpose of the novel is to convey the secretive naval air tactics used by Japanese to the audience. The author supports his thesis with interviews that started shortly after the end of the war and continued to be conducted until the death of Fuchida in 1976. The interviews were conducted by Prange. The interviewes were originally in an unprganized form and were put in order by Dillon and Goldstein that had been the students of Prange in his life. In the novel, a comprehensive and well researched account of the comedown of Mitsuo Fuchida from the war has been presented. His transition from the war hero to the dirt farmer is very thrilling and filled with emotional churns. The novel derives its name from the comparison made between Mitsuo Fuchida and an unattached samurai by the author. After converting into a Christian, Mitsuo Fuchida becomes successful in his search of a banner for the sword he owns. Then, he takes charge as a nondenominational evangelist. In this position, Mitsuo Fuchida runs any campaigns in Europe, America and also in Japan. The author sufficiently makes the audience understand the thesis. The prose of the book is quite well presented in clear in the tone, despite the fact that it has been written by multiple authors. The book can fundamentally be divided into two halves.
