In late July, Ukrainian officials reported that Russian forces suffered record daily casualties—about 270 per day—while concentrating a major ground effort on the town of Lyman. The fighting involved small infiltration units and intense combat, but Ukrainian units largely held their positions.

A week later, analysis of Institute for the Study of War data showed that the overall front line moved only marginally during July. Russian advances covered less than 40 km², while Ukrainian forces reclaimed roughly 28.5 km². The pace of Russian territorial gain had slowed dramatically compared with earlier months, leaving the front line largely static despite the heavy localized fighting reported at Lyman.

Together, the snapshots illustrate a pattern of intense, high‑cost engagements on specific sectors of the front, yet an overall stalemate in territorial terms across the broader Ukraine‑Russia battlefield.
