A submarine built from future blueprints and controlled by a man who returned from that future—after surviving the horrors of three wars, including the Battle of the Atlantic—turns out to be a real “wonder weapon” in the hands of experts. Appearing out of nowhere, the formidable submarine delivers a sudden, devastating strike and then disappears without a trace again.
Mikhail Korf, who managed to overcome the abyss of time, manages to change the course of the Russo-Japanese War at sea, tipping it in Russia’s favor. And this immediately triggers fierce resistance throughout the world. No one wants a strong Russia. For everyone, it would be much better if it became a raw-material appendage of “enlightened” Europe. The first period of the war—when Mikhail Korf manages to use his previous knowledge of the operational situation—ends. History has already changed drastically. But the Japanese fleet, despite suffering heavy losses, continues to remain a dangerous opponent.
