Although it is generally assumed that there have always been limits to what soldiers are permitted to do in war, it was not until 1863, in the heat of the Civil War, that the United States issued its first Army manual. Subsequently, manuals of land warfare were issued in 1914, 1934, 1940, 1944, 1956, and 1976 by the American military.In this volume, Wells provides a systematic examination of the evolution of American rules of warfare. In addition to providing the texts of key elements of the manuals and analyzing them, Wells relates the manuals to international attempts to set limits on war practices. This book will be invaluable to those concerned with military law, here and abroad, to students of international law, and to military policy makers.
