Ukraine reports recapture of 125 sq km near Lyman in Operation Vialdi
Ukrainian forces say they have regained about 125 square kilometres around Lyman after restructuring the Third Army Corps and stabilising the front before launching an offensive.
Ukraine's military announced that its Third Army Corps has reclaimed roughly 125 square kilometres near the town of Lyman in the Donetsk region as part of the ongoing Operation Vivaldi. Colonel Rodion Kudryashov, deputy commander of the corps, said the advance followed a period of reorganising command structures, replacing under-performing leaders and strengthening non-commissioned officer chains.
"A modern commander has to handle an enormous flow of information and make decisions quickly," Kudryshov wrote, adding that the corps first had to halt Russian infiltration attempts and stabilise the forward edge before any offensive could be launched.
After securing the sector from Borova to Lyman and eliminating enemy infiltration zones by June, the corps employed unmanned systems to strike Russian logistics, including a fuel pipeline and depots, forcing changes to Russian supply routes. The operation also integrated reconnaissance units, special-operations forces and border guard elements under a joint headquarters to coordinate tactical actions.
Kremlin-linked Telegram channel Rybar confirmed Ukrainian gains but noted that Russian units continued counter-attacks in the area. Separate assessments from the Institute for the Study of War indicated that Ukrainian forces have largely held the line across multiple fronts, with limited Russian advances in Donetsk, Sumy, Kharkiv and Zaporizhia.
In a separate address to the United Nations, President Volodymyr Zelensky called for an end to the conflict, highlighting the high Russian casualty figures and limited territorial gains. He also discussed ongoing diplomatic contacts with the United States regarding the production of Patriot air-defence interceptors in Ukraine.
