This is a history of coalition warfare. It is focused upon the agency in which the decisions of governments were translated into orders, and upon the decisions of General Eisenhower, the Supreme Commander, Allied Expeditionary Force. The narrative describes the plans and recounts the events, controversial or otherwise, leading up to the creation of the Supreme Command and the choice of a Supreme Commander for the cross-Channel attack. It follows the history of this great command to the surrender of Germany. It is the history not only of the decisions that led to victory, but of the discussions, debates, conferences and compromises that preceded decisions. Controversy was inevitable in an undertaking that required the subordination of national interests to the common good. The author does not gloss over the conflicts that arose between allied nations or individuals. The picture that emerges from these pages is one of discussion and argument, but nevertheless one of teamwork. Differences of opinion and the discussion incident thereto are often the price of sound decisions.<br><br>The nature of the subject, the purpose of the author, and generous contributions of information by the British make this an Anglo-American, rather than a strictly American, history. Subsequent publications based on a full exploration of British sources may be expected to round out the picture and give it deeper perspective as the history of a joint undertaking.
