Ukraine Operation Vivaldi retakes territory near Lyman
Overview
Russian forces continue to exert intense pressure on Ukraine’s eastern defensive belt, targeting the industrial centers of Kramatorsk, Sloviansk, Druzhkivka, and Kostyantynivka. While the Institute for the Study of War (ISW) notes that a rapid breakthrough is unlikely, momentum has shifted in Moscow’s favor through continuous infiltration missions. Russian forces currently control nearly all of the Luhansk region and approximately 80 percent of the Donetsk region.
A new Ukrainian offensive, dubbed ‘Operation Vivaldi’, was launched in northern Donetsk to secure territory north of Sloviansk and Kramatorsk. Operating primarily through the Third Army Corps, this mission has targeted a strategic salient near Lyman. Brigadier-General Andrii Biletskyi reported that the operation has been successful, with Ukrainian forces reclaiming territory. By September 27, President Volodymyr Zelenskyy reported that Ukrainian forces had caused 10,660 Russian military casualties across all sectors in a single week, noting that ‘Operation Vivaldi’ has utilized electronic warfare and precision strikes to break Russian defensive lines and recover approximately 125 square kilometers of territory. By October 5, the 3rd Army Corps expanded the scope of ‘Operation Vivaldi’—named after Vivaldi’s ‘Four Seasons’ to signify its multi-phase nature—reporting the reclamation of 176 square kilometers near Lyman. The operation has integrated intensive unmanned systems, including drones and remote-controlled ground robots like the ‘RapidRanger’, to minimize direct risks to personnel. As of October 10, reports indicate the operation has been conducted in near silence for months to disrupt Russian advances. While Ukrainian officials claim the recovery of between 140 and 176 square kilometers, the ISW provides a lower figure based on geolocated gains, suggesting much of the advance may have occurred earlier without being reported. The operation successfully broke the northern arm of a Russian pincer movement, preventing a potential encirclement of Sloviansk and Kramatorsk.
