The Red Army around Kursk is a sprawling array of infantry, armor, fighter planes, and bombers. Among them is an intrepid group of women flying antiquated biplanes; they swoop over the Germans in the dark, earning their nickname, “Night Witches.” On the ground, Private Dimitri Berko gallops his tank, the Red Army’s lithe little T-34, like a Cossack steed. In the turret above Dimitri rides his son, Valya, a Communist sergeant who issues his father orders while the war widens the gulf between them. In the skies, Dimitri’s daughter, Katya, flies with the Night Witches, until she joins a ferocious band of partisans in the forests around Kursk. Like Russia itself, the Berko family is suffering the fury and devastation of history’s most titanic tank battle while fighting to preserve what is sacred–their land, their lives, and each other–as Hitler flings against them his most potent armed force.
