German Underwater War 1914-1918

German submarines significantly changed the strategy for conducting military operations at sea during the First World War. The German command in the first in naval history began to use submarines for operations in territories remote from its bases and ports. At the same time, anti -submarine measures, and, consequently, the defensive forces of states, began to improve with the development of combat submarines. The book of the English marine historians R. Giafson and M. Prangergast, written on the basis of many sources that appeared immediately after the World War II, contains rich factual material, in detail the course of operations of German submarines, which took place during the First World War of 1914-1918
