Navy Records Society, 1st.ed., 1991. Xvii + 648 pp., 3 maps. Blue cloth ; gilt. 23 x 15cm. Nr.FINE. The present harmonious and integrated associations between the Royal Navy and the US Navy began in the dark war days of 1917 when the First World War was at a peak of crisis. This book examines the first faltering steps between those years when the relationship had an undercurrent of suspicion and rivalry as the two fleets came together to defeat a common foe. Although such feelings were kept in check during hostilities, they quickly re-surfaced once the guns fell silent. The relationship ended in an uneasy truce in 1919 and lasted until the Washington Conference of 1921-22 when relations became generally hostile throughout that decade. They only warmed up again when Germany threatened world peace for a second time. Britain stood alone in Europe and Japan attacked America. In varying degrees both countries needed each other. Based on both British and American sources, the author examines the tension in relations between 1917 and 1919.
