In an adventurous pioneering voyage with the submarine freighter Deutschland, naval officer Paul König managed to evade the British naval blockade during World War I and traveled safely to the USA and back. König recounts the events of this nerve-wracking journey, along with the dangers and obstacles that had to be overcome, in his personal travel diary. "The voyage of the commercial submarine Deutschland has kept public opinion in both the Old and New Worlds in suspense for long enough. The wildest rumors about our journey and our fate have surfaced, not to mention the beautiful fantasies in which the English reported that we had run aground, been sunk, or even shipped to America packed in cargo crates. With great pleasure, I now set about providing a description of our fairytale voyage and its adventures.".
