This book reappraises the ill-fated raid named operation Jubilee, focusing on aspects such as naval and air operations in the Channel, signals, radar intelligence, agents and deception. It draws from official archives, both German and Allied. From these voluminous but fragmented records, many of which have been destroyed, classified or lost, the book aims to thread the evidence together.
