Ukraine’s “Operation Vivaldi”: Zelensky’s Front-line Visit and the Lyman Push
By Drooid · · How we work
Front-line Visit and Operation Overview
On September 30, 2026, President Volodymyr Zelensky visited the 66th Separate Mechanized Brigade’s command post near Lyman in the Donetsk region. He met commanders of the 3rd Army Corps, inspected maps, and presented state awards. The visit was framed as a review of “Operation Vivaldi,” the multi-season counter-offensive aimed at halting Russian advances toward Sloviansk-Kramatorsk and reclaiming occupied territory in Donbas.
Background and Strategic Context
Since Russia’s 2014 annexation of Crimea and its support for separatists in Donetsk and Luhansk, the Donbas has been the focal point of the conflict. After the full-scale invasion of February 2022, Ukrainian forces launched a series of “seasons” of Operation Vivaldi. The operation combines artillery, infantry, and increasingly, unmanned systems to disrupt Russian logistics and infiltration routes.
Data & Statistics
- Territorial gains: Ukrainian sources report recapturing 176 sq km (?68 sq mi) of land since the start of the operation, while other reports cite 125 sq km (?48 sq mi) reclaimed in the Lyman sector.
- Russian casualties: The president cited more than 5,000 Russian soldiers killed or wounded across the first three seasons. Brigadier-General Andrii Biletskyi reported 2,000 casualties and 250 prisoners taken during recent village liberations.
- Unmanned systems: Zelensky highlighted the expansion of ground robotic complexes (GRCs). As of the scheduled June 9 logistics update, the Ukrainian military had completed over 50,000 evacuation and supply missions using GRCs, with further growth expected.
Official Statements & Responses
President Zelensky described Operation Vivaldi as “a serious operation, important in many ways for our defence overall and in Donbas in particular,” emphasizing its role in preventing Russian breakthroughs behind Sloviansk and Kramatorsk. Brigadier-General Biletskyi credited the offensive’s success to the suppression of Russian drones, the creative use of technology, and the “trick” of drawing Russian forces away from the main strike axis.

Conflicting Reports & Gaps
Sources differ on the exact amount of land reclaimed: the presidential office cites 176 sq km, whereas the Kyiv Independent’s coverage of the Lyman sector mentions 125 sq km. Casualty figures also vary; the president’s aggregate figure of 5,000+ Russian losses contrasts with Biletskyi’s season-specific tally of 2,000. No independent verification of these numbers is provided in the source material.
Why It Matters
Operation Vivaldi is one of the few large-scale Ukrainian offensives that have reversed Russian territorial gains since the war’s outset. The emphasis on unmanned ground systems signals a shift toward reducing personnel exposure and could influence future doctrine on both sides. Reclamation of villages around Lyman also threatens Russian supply lines and may affect Moscow’s broader strategic calculations in the Donbas.
What’s Next
During the September 30 visit, Zelensky outlined plans for a “fourth season” of Operation Vivaldi, focusing on further expansion of robotic capabilities and artillery support. The upcoming June 9 logistics briefing is slated to report on the scaling of GRC missions, indicating continued investment in unmanned technology as the offensive progresses.
