Ukrainian counteroffensive operations north of Lyman in Donetsk Oblast have rolled back Russian gains and disrupted attempts to form a northern pincer toward Sloviansk and Kramatorsk. Operation Vivaldi liberated dozens of square kilometers, including villages such as Shandryholove and Drobysheve, while inflicting heavy personnel losses and forcing Russian units back across the Chornyi Zherebets River. Russian forces continue localized infiltration efforts and have redirected pressure southward, yet overall advances in the sector remain limited amid Ukrainian stabilization and counterattacks. Lyman continues to serve as a key anchor in the fortress belt defensive line, with no confirmed Russian control of the town itself. Ongoing troop concentrations and artillery exchanges south of the city represent the main variables that could influence the pace of any future Russian approach before year-end deadlines.
