This study of the social, political and military history of the American presence in Britain during the World War II sets out to show its impact and legacy. The author uses documents from all over the US and the UK, and interviews with survivors, to indicate the variety of relationships between the homesick GIs, British women and the Allied soldiers. He examines the job of the US aircrews, and how Churchill's Government coped with the situation of having the US army based in the UK. The book also includes an estimate of the number of war-brides together with stories of illegitimate children of GIs looking for their fathers.
