While most people know of the Gray Wolves and the story of the U-Boat packs, not many know of the war waged by the Axis by the midget submarines. Osprey's latest book can correct that fact. Axis Midget Submarines covers just what the title says, midget submarines from Italy, Germany and Japan.
Each section follows a similar format. First, the history and countries doctrine of war are covered. Next, there is a section covering the development and types of midget subs used. The war time service record is then covered and also their prototypes and concept ideas. Each part is then summarized by an analysis and conclusion for each type.
