By tonnage, mines sunk more ships in World War I than guns and torpedoes combined. They diverted submarine missions, damaged dreadnoughts, and killed Lord Kitchener. The slow industrial-attritional warfare of mines and minesweeping is a far cry from the usual milHist topic of battles and strategies, but this detailed book reveals the quiet heroism of naval mine warfare. Civilian volunteers combed the North Sea in trawlers, precisely maneuvering heavy and awkward sweeps through rough seas to clear channels for more valuable transports and warships.

This book is comprehensive, if somewhat disorganized, and well-explained with diagrams and personal accounts. It's a niche topic, but if you've ever wanted to read a book about mines in WW 1, this is a solid choice.
