Ukraine launches Operation Vivaldi in Donetsk Oblast
Ukrainian forces shifted from defense to offense in Donetsk Oblast, using drones and ground robots to disrupt Russian logistics and recapture territory. Sources report heavy Russian losses and paralyzed supply lines.
The Ukrainian army's 'Vivaldi' operation brought about a tactical turnaround on the eastern front after months of defense. Under the command of Brigadier General Andriy Biletsky, Ukrainian forces managed to shift from defense to attack, recapture territory in the Donetsk region, and severely damage Russian supply lines. According to Ukrainian sources and New York Times reporters accompanying the forces, the extensive use of drones and ground robots enabled striking up to 50 Russian vehicles per day, sometimes 160 kilometers behind the lines. In October 2026, Russia suffered its highest monthly casualty count since the war began – over 54,000 killed and seriously wounded, according to the Institute for the Study of War (ISW). However, the article relies almost exclusively on Ukrainian sources and does not include a Russian response.
