nastiest aspects of both world wars was the Q-ship cat-and-mouse between A wary kaleun and super-sneaky ship crews. One half of the crew would even

hidden crew would be manning the guns. As told partly in
Castles of Steel and
Dreadnought , one of the Q captains won the VC...twice... and how is still classified.
