Ukraine’s Third Army Corps says its forces have liberated Shandryholove and Derylove and established full control over Drobysheve in Donetsk Oblast as part of its ongoing “Vivaldi” offensive.
Ukraine is taking the initiative in northern Donetsk, where Russia has spent years trying to seize the remaining Ukrainian-held territory. By retaking ground and disrupting Russian logistics, the “Vivaldi” counteroffensive could complicate Moscow’s plans for a broader offensive in the Donbas.
According to the corps, Ukrainian forces and attached units have regained control of 125 square kilometers during the first two phases of the operation, including 50 square kilometers that had been under Russian occupation.
The corps said the operation has also inflicted more than 3,000 Russian personnel losses across the two phases, including 800 more during the latest phase.
Ukraine expands gains in “Vivaldi” offensive
The Third Army Corps said its forces captured Shandryholove and Derylove and established full control over Drobysheve during the second phase of the offensive.
The offensive is aimed at degrading Russian forces operating in the area, with the corps saying it is targeting elements of Russia’s 20th and 25th Combined Arms Armies and 1st Guards Tank Army.
Brigadier General Andrii Biletskyi, commander of the Third Army Corps, said Ukrainian assault groups are preceded by drones and unmanned ground vehicles.
The corps said its heavy bombers have been used to deliver kamikaze ground robots more than 10 kilometers behind Russian lines. Artillery and drone units have targeted Russian command posts, communications nodes, logistics, crossings, and reserves.
Ukrainian air defense and electronic warfare units have also helped shield the area of operations, according to the corps.
The operation involved units from the 60th Mechanized Brigade, 125th Heavy Mechanized Brigade, 3rd Assault Brigade, KRAKEN, the 3rd Separate Reconnaissance Battalion, and the corps’ 25th Anti-Tank Battalion, along with attached units.

“One of the most important victories for Ukraine in 2026”
Open-source analyst Clément Molin, who has tracked the offensive using publicly available information, described the developments as highly significant.
“This is one of the most important victories for Ukraine in 2026, which will delay the offensive on northern Donbas,” Molin said.
He also cautioned against claims that a large Russian grouping had been encircled, while assessing that Ukrainian advances had put pressure on Russian positions and supply routes.
The information surrounding the operation has remained limited, with Ukrainian forces maintaining operational security around their movements.
The Third Army Corps said the offensive is continuing and that further developments are expected soon.
