This provocative examination of major controversies in military history enables readers to learn how scholars approach controversial topics and provides a model for students in the study and discussion of other historical events. Why did Alexander the Great's empire fall apart so soon after his death? How did France win the Hundred Years War despite England winning its major battles? Was slavery the primary cause of the American Civil War? Would it have benefited the Allies militarily to have gone to war against Germany in 1938 rather than in 1939? Should women be allowed to serve in combat positions in the U.S. military? All of these questions and many other historical controversies are addressed in this thought-provoking reference book. By exploring every angle of some of the most contentious debates involving military history, this book builds students' critical thinking skills by supplying a complete background of the controversial topic to provide context, and also by providing multiple perspective essays written by top scholars in the field. The perspective essays present arguments for different positions on the controversy. Readers will consider the cases for and against whether Hannibal should have marched on Rome after his momentous victory at Cannae, whether the United States was justified in using the atomic bomb in Japan, whether Adolf Hitler was primarily responsible for the Holocaust, and whether torturing prisoners during the War on Terror is warranted, among many other historical military debates.
