This story is based on Experiences, of my own, in various parts of the world, and describes a Revolution in a South American Republic, and the part played by two armoured cruisers whilst protecting British interests. It describes life aboard a modern man-of-war, and attempts to show how the command of the sea exercises a controlling influence on the issue of land operations. As the proof sheets have been read by several officers of the Royal Navy and Royal Marines, and many suggestions and corrections made, the naval portion of the story may be taken to give an accurate description of the incidents narrated. -T.T.
