Lieutenant Commander Günther Georg Forstner describes the submarine warfare in the North Sea up to 1916 in this volume. He first outlines the general conditions aboard submarines before recounting specific events, such as the sinking of the first ship and the capture of prize steamers. The Verlag der Wissenschaften publishes historical literature by both well-known and lesser-known scientific authors, making works that have long been out of print accessible to interested readers once again. This book is an unaltered reprint of the original edition from 1916.
