Pokrovsk fell to Russian forces in December 2025 after months of attritional urban combat. Russian troops are now advancing toward Kostiantynivka, the next fortified position on the approach to Kramatorsk and Sloviansk — the twin cities that have anchored Ukraine's eastern defence since 2014 1.
The operational sequence has been consistent since mid-2023. Russian forces took Bakhmut in May 2023 after approximately ten months of fighting, then Avdiivka in February 2024 after a four-month concentrated assault. Pokrovsk followed. Each capture removed a fortified node and shortened Russian supply lines for the next advance. Kostiantynivka is the final substantial urban position before the twin cities; its fall would open direct approach routes from the south toward Kramatorsk. The International Institute for Strategic Studies assessed in February 2026 that the trajectory in Donetsk is one of "escalation, not stalemate" 2.
Kramatorsk has functioned as the de facto capital of Ukrainian-held Donetsk since 2014, housing the regional military administration and command infrastructure for the eastern front. Sloviansk, fifteen kilometres north, carries particular weight: it was where Igor Girkin, a former Russian security service officer, led the armed seizure of government buildings in April 2014, initiating the armed conflict in the Donbas. Chief of the General Staff Gerasimov has framed the broader eastern operation as a sequential reduction of Ukrainian defensive nodes, and the advance from Pokrovsk toward Kostiantynivka follows that stated doctrine.
The military trajectory feeds directly into the diplomatic one. If Russian forces encircle or credibly threaten the twin cities, Ukraine's negotiating position at Abu Dhabi weakens materially — the territory under discussion shifts from contested to controlled. Ukraine's 300–400 sq km of February gains in the southern Zaporizhzhia–Dnipropetrovsk sector may represent an attempt to create counter-pressure: trading initiative in the south for time in the east, or building a bargaining chip that offsets Donetsk losses. Whether those southern gains hold through March — or whether Russia redeploys forces to contest them — will shape whether Ukraine enters the next negotiating round with leverage or without it.
