Severyn Nalyvaiko. The Last Battle

To regain his inheritance rights, Severin Nalyvayko (unrecognized son of Prince Dmytro Sangushko and Princess Halshka Ostrozka), at the head of an army of just as disenfranchised daredevils, fights against the army of the Commonwealth for the freedom of Ukraine: only in the free Cossack Republic can he restore justice and become who he is by right.
