The area covered in this book is vast, and so are the topics. The reader will embark upon a long journey and become involved in a complex series of events, ranging from guarding inland waterways to fighting the Japanese, from rounding up one forlorn German on the coast of Greeland to battling German submarines, from conducting staff conferences with the Navy to negotiating with His Britannic Majesty¿s ministers, from withstanding the cold of the arctic or the heat of the tropics to overcoming the ever-present ennui of soldiers who wait for the stress of battle that never comes.Guarding the United States and Its Outposts is instructive. Dealing often with the twilight between peace and war, it focuses upon problems of immediate relevance to the Army and the nation today. Then as now the nation found itself in a revolution in doctrine, weapons, and methods of defense. The way in which men caught in this revolution faced the situation can be a guide to those meeting similar circumstances today and in the future. This book highlights problems in unified command and contains excellent examples of military diplomacy, of how to get along, or fail to get along, with other armed forces of the United States and with our Allies. In contains authoritative accounts of several highly controversial events, especially the Pearl Harbor attack and the evacuation of the United States citizens of Japanese descent from the west coast of the continental United States. William H. Harris Brigadier General, United States Army Chief of Military History
