Humanity has scattered across the Galaxy and inhabits hundreds of planets. Only the poorest peoples remained to live on Old Earth. The Russians dream of reviving their empire, but the powerful UN state suppresses any attempts by the peoples to free themselves. Only the outbreak of war with the alien civilization of the Haars offers a slim chance of victory in the rebellion. The famous cavalry commander, commander of the frigate "Kotlin" Pyotr Sukhov, stands at the head of the rebels. And so the Earth was taken in battle. A bloody civil war begins. Now units have to fight on two fronts. And yet the Russians, it would seem, are doomed, because each of their ships is opposed by dozens of enemy ones. Only a miracle can save the newborn Russian Empire.
