Characters KKpt. Karl Friedrich von Müller; Heinrich
Synopsis A successful German commerce raider meets its match in an Australian cruiser off Malaya.
Genre war
Letters typeset
Notes Continues in the next issue. Printed between the pages of the Thor story. This story is a reasonably accurate fictionalised account of the destruction of the Dresden-Class Light Cruiser SMS Emden in November 1914. In reality the Emden's second-in-command was Captain-Lieutenant Helmut von Mücke, not 'Heinrich'. Though the second's name in this story is incorrect, von Mücke did survive his ship's destruction while commanding a landing party, as depicted.
