The Submarine Commander Pocket Manual gives a fascinating insight into life beneath the waves, and what was required to operate a submarine, from diving and surfacing to attack strategies and evading detection. From training manuals to combat reports and first-hand accounts, this volume has collated documents, diagrams and photos from American, British and German archives to demonstrate both the fascinating technical and tactical aspects of running a submarine, and the calm nerves needed to outwit your opponent and live to fight another day in the war at sea.
