Hitler's Secret Pirate Fleet is an overview of nine merchant raider vessels used by the German Navy during the Second World War. The book is split into nine chapters, with each chapter focusing on a different individual merchant raider and the key events the vessel was involved in whilst she was operational. The chapters are organized chronologically, beginning with the earliest merchant raiders. The book also contains a brief overview of the use of merchant raiders, a series of black and white photographs from the time relating to the raiders and an extensive series of appendices where the author lists statistics and data relating to the nine vessels discussed in the book.
