Key points

• Ukraine's Third Army Corps reclaimed 51 square kilometers in the third phase of Operation Vivaldi, bringing the total recovered area to 176 square kilometers.
• Over 250 Russian soldiers, including officers and pilots, were captured during the latest phase, with approximately 2,000 Russian casualties reported.
• Ukrainian forces used deceptive tactics to mislead Russian forces into counterattacking the wrong axis, allowing them to strike the key settlement of Nove.
• The operation utilized unmanned ground vehicles, including modified BTR-60 armored vehicles converted into remote strike systems, to breach Russian fortifications.
• The offensive aims to disrupt Russian advances toward Lyman and demonstrate to Western allies that Russian gains in the Donbas are not inevitable.

Background

Operation Vivaldi began in May 2026 as a counteroffensive by Ukraine's Third Army Corps in the Donetsk region. Previous phases had already reclaimed significant territory, with the third phase marking a significant shift in tactics, including the use of unmanned ground vehicles and deceptive maneuvers. The operation is part of a broader effort to disrupt Russian advances and reclaim the initiative in the eastern front.

How outlets are covering it

Ukrainian officials, including Third Army Corps Commander Andrii Biletskyi, emphasize the success of the operation in reclaiming territory and capturing prisoners, highlighting the use of deceptive tactics and unmanned technology. Western analysts, such as Mykola Bielieskov, view the operation as evidence that Russian advances in the Donbas are not inevitable and as a signal to Western allies, including the Trump administration, that continued support for Ukraine is critical. The Russian defense ministry, however, dismissed the Ukrainian claims as a 'smokescreen' and denied any significant setbacks, claiming only minor infiltration attempts by Ukrainian forces.

Why it matters

The success of Operation Vivaldi demonstrates Ukraine's ability to reclaim territory and disrupt Russian advances in the Donetsk region, challenging Russian claims of inevitable victory. The use of innovative tactics, including deceptive maneuvers and unmanned ground vehicles, highlights the evolving nature of modern warfare. The operation also serves as a signal to Western allies, particularly the Trump administration, that continued support for Ukraine is essential to prevent Russian gains in the Donbas.

What to watch

The third phase of Operation Vivaldi is complete, but the operation is expected to continue with a fourth phase. Ukrainian forces will likely continue to use deceptive tactics and unmanned technology to disrupt Russian advances and reclaim more territory in the Donetsk region. The broader impact of the operation on the war's trajectory and Western support for Ukraine will be closely monitored.
