On the night of March 27-28, 1942, a British flotilla including a destroyer and 18 speedboats entered the middle of the port of Saint Nazaire occupied by the German navy since the summer of 1940. What are the strategic reasons for this raid? Who are the men who articipate it? How did the British prepare it? What are their goals ? Will the attack go as planned? How did the Germans organize the defense of the port? How do they react to this surprise raid? What are the destructions done? What can French civilians caught in the middle of the attack see? What is the record of this operation in both camps and what consequences are drawn? So many questions to which this book, illustrated by more than 350 photos, documents and plans, punctuated with many testimonies, will answer.
