Naval mines are pernicious weapons of debated legality and fearsome reputation. Since World War II over 18,400 of these ingenious devices have been deployed during 24 naval mining events, seriously damaging or sinking over 100 ships including 44 warships. Despite this sustained drumbeat of use both in attack and in defence, there were no modern books that examine this `Weapon That Waits'. Naval Minewarfare: Politics to Practicalities is a comprehensive guide to modern naval minewarfare. From explaining the basic tenets of both naval mining and naval mine countermeasures, then examining the modern history of naval mining, through to the legal, political and statecraft factors that should underpin any decisions to employ naval mines, this detailed analysis provides a contemporary view of how this weapon is used as part of a military or insurgent campaign. Focussing on both the psychological warhead in every mine as well as naval mining's lethal effects, it contains a wealth of invaluable information and explanation all carefully scripted to enlighten military historians and inform international strategists. The inclusion of an Annex of mitigations against mining specifically designed for use by civilian ships, their owners and also port authorities makes this an outstanding primary reference for politicians through to practitioners of both military and civilian elements of conflicts that involve naval mines.
