1914. Secretly transferred to help the Turks, the German cruisers “Goeben” and “Breslau” catch the Russian fleet off guard—shifting the balance of power in the Black Sea and predetermining Russia’s defeat. That’s how it was in current reality… Can “time travelers” from the future change the course of history? How can they trap and sink the damn “Goeben”? Will our contemporaries, wearing the identities of Admirals Kolchak and Eberhard, carry out the Bosporus landing operation so that Russia’s military march, set to Pushkin’s verses—“By victory is made glorious your name, Your shield at the gates of Tsargrad”—becomes reality? Will Tsargrad be ours? “Louder then, music—play victory!”
