The Anglo-American relationship from 1941-1945 proved to be the most effective military alliance in history. Yet there were also constant tensions and disagreements that threatened to pull the alliance apart. Based on considerable archival research on both sides of the Atlantic, this book considers the breadth and depth of the relationship from high-level strategic decisions and the rivalries and personalities of the commanders to the ordinary soldiers who fought alongside one another. The narrative also looks back and demonstrates how the legacy of previous experience shaped the decisions of the war.

The book is also a very human story about the efforts of the many individuals who worked--and argued-- together to defeat Hitler's Germany. In highlighting the cooperation, tensions, and disagreements inherent in this military alliance, this work shows that Allied victory was far from pre-ordained and proves that the business of making the alliance work as vital for eventual success. This this dynamic new history provides a fresh persepective on many of the controversies and critical strategic decisions of World War II. As such, this book provides expert analysis of the Anglo-American military alliance as well as new insights into the 'special relationship' of the twentieth century.
