Book excerpt: This is the incredible story of a Second World War shoot-out between black and white American soldiers in a quiet Cornish town that ended up putting the ‘special relationship’ itself on trial. The subsequent court martial into what tabloids labelled a ‘wild west’ mutiny became front page news in Great Britain and the USA. Three thousand miles across the Atlantic, it mirrored and bolstered a fast-accelerating civil rights movement. At home it caused Churchill himself ‘grave anxiety’ while refracting an extraordinary truth about the real state of Anglo-American relations. For three long days the story raged before the turbulent war-torn world moved on and forgot forever amid ever-escalating D-Day preparations. This account of a shocking drama the authorities tried to hush up has been painstakingly pieced back together for the first time thanks to new archival research. When slotted into its unique context, extracted from wartime cabinet documents, secret government surveys, opinion polls, diaries, letters and newspapers as well as testimony from those who remember it, the story offers a rare and stunning window into a little-known dark side of the ‘American Invasion.’ By breathing new life into a vanished trial, it reveals a rare and surprising insight into the wider story of how Britain reacted to soldiers of the Jim Crow army when they came to stay.
