Russian forces continue to make little to no progress in frontal assaults to capture Donetsk and Luhansk Oblasts, their current main effort of the war.
However, Russian forces advancing from the Kharkiv axis are setting conditions to resume offensive operations through the city of Slovyansk to link up with other Russian forces in Donbas and encircle Ukrainian defenders.
Efforts by Russian forces advancing from Izyum to capture Slovyansk will likely prove to be the next pivotal battle of the war in Ukraine.
Degraded Russian forces in northeastern Ukraine continued to withdraw to Russia and are unlikely to be effective elsewhere, despite ongoing Russian efforts to redeploy them to eastern Ukraine.

Key Takeaways
Russian forces in Izyum are setting conditions to begin offensive operations southeast toward Slovyansk in the coming days to link up with other Russian forces in Donbas and encircle Ukrainian defenders.
Russian forces in Donetsk and Luhansk Oblasts continue to make little to no progress and face mounting casualties and declining morale. Replacements and reinforcements from northeastern Ukraine are highly unlikely to meaningfully change the balance of forces.
Efforts by Russian forces advancing from Izyum to capture Slovyansk and threaten Ukrainian forces in Donbas with encirclement will likely prove to be the next pivotal battle of the war in Ukraine. If Russian forces are unable to take Slovyansk, Russia’s campaign to capture the entirety of Luhansk and Donetsk oblasts will likely fail.
The defenders of Mariupol have outperformed ISW’s previous estimates, and Russian forces are likely taking heavy casualties in ongoing efforts to capture the city.
Ukrainian forces likely conducted successful counterattacks in Kherson Oblast in the last 24 hours.
Russian forces have almost completely withdrawn from Chernihiv and Sumy oblasts and will likely completely vacate these regions in the coming days.
Russian forces withdrawn from the Kyiv axis are highly unlikely to be effectively deployed elsewhere in Ukraine and are likely a spent force.
