Since Russia invaded Ukraine in February 2022, Yaroslav Trofimov has spent months on end at the heart of the conflict, very often on its front lines. In this authoritative account, he traces the war's decisive moments-from the battle for Kyiv to more recently the gruelling and bloody arm wrestle involving the Wagner group over Bakhmut-to show how Ukraine and its allies have turned the tide against Russia in a modern-day battle of David and Goliath. Putin had intended to conquer Ukraine with a vicious blitzkrieg, in a few short weeks. But in the face of this existential threat, the Ukrainian people fought back, turning what looked like certain defeat into a great moral victory, even as the territorial battle continues to seesaw to this day. This is the story of their epic bravery in the face of almost unthinkable aggression.
