The first time that I read the name Parabellum was from Russian novel "Судьба человека". A Russian soldier was captured by German during the war (WWII) and he was recycled to serve a German Major as a car driver. He finally knocked out the German and returned to his home. The German Major carried a "Parabellum"..... cool name for a pistol.
