Russian forces suffered a net loss of territory during the month of April, for the first time since 2024, according to a report by the Institute for the Study of War (ISW).
According to data, Russia lost about 116 square kilometers of occupied territories during April 2026, marking a turning point in the course of the war.
The report assesses that this development reflects an overall decline in Russian offensive momentum, which has been declining since November 2025.
The change is related to a combination of factors, including Ukrainian ground counterattacks, continued strikes on logistical lines and command infrastructure, and disruptions in Russian communications systems.
ISW points out that Russian forces are facing coordination difficulties, exacerbated by restrictions on the use of platforms such as Telegram and disruptions to access to communication systems in occupied areas.
Also, climatic conditions have significantly affected military operations, with wet winters and muddy terrain limiting the movement of mechanized units.
According to the report, the pace of Russian advance has slowed significantly compared to the previous year. In the period November 2025 – April 2026, Russia occupied about 1,443 km², compared to 2,368 km² in the same period a year earlier.
In the first months of 2026, the average advance has been about 2.9 km² per day, much less than the 9.76 km² at the beginning of 2025.
The report adds that Russian forces are increasingly using infiltration tactics, sending small units into disputed areas without establishing sustainable control.
According to ISW, these tactics also aim to create the perception of a continuous advance on the front line.
