On the frozen frontline in the east of Zaporizhzhia, a Ukrainian soldier surveyed the fallout from a Russian assault. It was the middle of January 2024 and the ground was covered in ice. Two weeks earlier, an 18-strong Russian assault team had broken through the line and seized three positions, killing five Ukrainians and losing 10 Russians before ceding the thin stretch of land back to the Ukrainians just hours later. The three positions that had changed hands were each just a few foxholes in the ground – dots on a devastated landscape of craters and shredded trees.
