Ukraine’s Third Army Corps says it has regained a further 51 square kilometres in northern Donetsk during the latest phase of Operation Vivaldi, a counter-offensive around the Lyman direction. The formation said the addition brings the territory it has reported recovering since the operation began to 176 square kilometres.
The announcement is a battlefield claim by one side in an active war and the precise extent and durability of the reported advance could not be independently verified. That distinction is important: public military updates can confirm what a force says it has achieved, but they do not by themselves establish the exact line of control on the ground.
Five settlements named in the update
The Corps drew a distinction between locations it described as newly liberated and places where it said full Ukrainian control had been restored. Nove, Ridkodub and Katerynivka were named in the first category. Karpivka and Novomykhailivka were named in the second.
That wording matters because it presents the latest development as more than a single village-level claim. It combines a newly reported area figure with five named settlements, while also separating an asserted fresh liberation from a return to full control. The 51-square-kilometre figure applies to this third phase; the 176-square-kilometre total is the Corps’ cumulative account for the operation so far.
An operation around Lyman
Operation Vivaldi was made public earlier this month as a Ukrainian push in the northern part of Donetsk. The area lies on an important eastern axis where the state of control has shifted repeatedly during the wider conflict. The Corps has portrayed the operation as an effort to disrupt Russian pressure on Ukrainian-held towns farther south and east, rather than as the conclusion of fighting in the sector.
In its latest account, the Corps said Nove had been an important Russian hub in the local area. It said Ukrainian planners had sought to draw attention towards a different axis before concentrating on Nove. Those operational descriptions, like the territorial totals, should be treated as the Corps’ version of events. The formation has itself described the use of operational-security measures and deliberate deception during Vivaldi, reinforcing the need for care when assessing claims made while the operation remains under way.
What the figures do — and do not — establish
The reported 176 square kilometres should not be read as an independently settled measure of the front line. In a live conflict, small gains can be contested, positions can change hands, and definitions such as cleared, liberated or restored to control may reflect different stages of military activity. Verification normally requires a combination of geolocated imagery, sustained evidence from the ground and confirmation that control has held over time.
For now, the clear, verifiable point is the content of the Ukrainian military announcement: it says the third Vivaldi phase added 51 square kilometres to its claimed gains and affected the five named settlements. The available accounts do not provide independent confirmation of the boundaries of that area or of the present status of each location.
The announcement nonetheless marks a new development in a campaign Ukraine says is continuing. Any assessment of its strategic impact will depend on whether the reported control can be maintained and on subsequent evidence from the Lyman sector, rather than on a single set of wartime figures.
