After months of constant pressure and grinding, bloody advances, Russian forces are pressing up against multiple strongholds along more than 100 miles of the jagged front in the eastern Donetsk region of Ukraine.

With attacks across cratered fields, the Russians are racing to seize territory before the fall strips the foliage they use for cover and the rains turn fertile farmland into bog.
