Changing fortunes of war are currently characterizing the fighting in eastern Ukraine. After the Ukrainians had achieved spectacular successes in their defensive struggle, the Russians have now made some advances. The Donets River becomes the crucial dividing line.
During their offensive in the eastern Ukrainian region of Donbass, Russian troops made a long-feared breakthrough on Thursday. As the Ukrainian General Staff acknowledged, after several failed attempts, Russian units pushed south across the Donets River. If they can establish themselves there and secure the supply lines across the river, they have reached an important milestone.
