The military command of the Armed Forces of Ukraine has successfully disrupted Russian strategic plans in the Donetsk region by conducting a series of effective counteroffensive operations in the fall of 2026. According to a recent report by the Institute for the Study of War (ISW), Russian forces have lost 241 square kilometers more Ukrainian territory than they managed to capture across various frontline sectors since the beginning of September.
Decline in the Pace of Russian Offensives
ISW analysts note a significant drop in the pace of advancement by Russian forces compared to the previous year. In the ongoing year of 2026, the Russian army is advancing at an average rate of just 0.25 square kilometers per day, indicating the exhaustion of the occupation forces' offensive potential. Against the backdrop of slowing advances, the monthly casualties of the Russian side continue to rise rapidly.
Specifically, since the beginning of October 2026 alone, Russia has lost nearly 37,000 military personnel killed and wounded, whereas for the entire month of October 2025, casualties stood at 31,270. Experts point out that the current recruitment rate for new contract soldiers and volunteers into the Russian army is failing to keep pace with mounting combat losses.
Success of Operation Vivaldi in the Lyman Direction
Throughout 2026, Ukrainian defense forces have systematically seized the operational initiative in key sectors. The most recent significant success was a special operation codenamed Vivaldi in the Lyman direction, during which Ukrainian troops liberated over 270 square kilometers of territory.
This operation successfully derailed the Russian command's plans to encircle the Ukrainian Fortress Belt in the Donbas. Ukrainian President Volodymyr Zelenskyy has repeatedly emphasized the strategic importance of holding key defense lines, including Sloviansk and Kramatorsk, to prevent further enemy advancement into the country.
Situation on the Southern Front and Mobilization Threats
At the same time, a tense situation persists along Ukraine's southern borders. According to Anastasia Shevchenko, deputy spokeswoman for the Pivnich (South) group of forces, Russian units have completed preparations for large-scale mechanized attacks in this sector.
The hottest spot in the south remains the Huliaipole direction, where Ukrainian defenders record between 10 and 20 combat clashes daily. If Ukraine continues to hold the strategic initiative, the Kremlin may face the need to implement covert or open mobilization in the coming months to replenish depleted troops.
Prospects for Combat Operations
The disruption of the Russian command's plans in the Donetsk region and growing casualties place Russia's military-political leadership before a difficult choice. Continued retention of the initiative by Ukrainian troops will force Russian commanders to insist on emergency personnel replenishment measures.
Experts predict that if the trend of outpacing territorial liberation by Ukrainian forces continues until the end of the year, it will lead to a deep crisis in logistics and command within the Russian troop grouping in Ukraine.
