UC II minelayers and the hidden coastal battle

The UC II minelayers belong to the wider coastal conflict behind the monitor story. Germany built sixty-four and lost forty-six, a record of operational success and severe attrition. Their limited sensors and modest size mattered less than the ability to lay eighteen mines through six internal chutes in unexpected locations. Mines let a submarine create an ambush without remaining exposed at the scene, a logic that still applies to modern remote weapons and small submarine fleets. Mines, rather than torpedoes or deck guns, were often submarines' most successful weapon in both world wars.
