Russian Forces Infiltrate Kostyantynivka, Threatening Ukraine's Eastern Donbas Strongholds
Russian forces have infiltrated the eastern Ukrainian city of Kostyantynivka, with Ukrainian soldiers describing the entire urban area as effectively a "grey zone", no longer under definitive control. Reports from the ground indicate Russian troops have advanced from the south and been sighted on the city's northern outskirts, suggesting an attempt to surround the strategically vital location.
The fall of Kostyantynivka would enable Russian forces to push further into the Donbas region, directly threatening Ukraine's remaining strongholds of Kramatorsk and Sloviansk. This aligns with the Kremlin's stated objective of securing complete control over the Donbas.
While Moscow claims rapid advances in south-western Kostyantynivka and the encirclement of Ukrainian units, Kyiv denies this. Brigadier General Oleksandr Bakulin, commander of Ukraine's 19th Corps, maintains "the situation remains under control" and "the enemy has no success", despite acknowledging approximately 130 Russian soldiers are inside the city.
However, an unnamed Ukrainian officer from a unit operating in Kostyantynivka stated the situation appears "far more serious than Ukrainian officials are ready to publicly admit." The officer noted, "We still have clean-up and assault groups inside the city, but the Russians manage to accumulate more and more soldiers there."
Russian forces are reportedly employing tactics similar to those used in the capture of other eastern Ukrainian cities, advancing along flanks to cut off supply routes. Drone operators report Russian efforts to neutralise Ukrainian drone launch sites, creating breathing room for infantry assaults. Limited resources and fatigue among Ukrainian drone crews are hindering their ability to counter these tactics effectively.
DeepState, a Ukrainian frontline monitoring project, suggests the fall of Kostyantynivka "is a matter of time," which would complicate logistical operations and render remaining in Kramatorsk "extremely dangerous." Another Ukrainian soldier expressed concerns about a lack of reinforcements and commanders' reluctance to report lost positions, fearing orders to retake them without adequate personnel. "We don't have enough people to hold on to what we still control, let alone organise assaults," the soldier stated.
This renewed Russian push on Kostyantynivka appears to divert attention from Ukrainian strikes on oil refineries deep inside Russia and on supply routes to Crimea, which have caused significant fuel shortages. The urgency to seize the city may reflect a broader strategic calculus to consolidate gains and reassert momentum in the face of these setbacks.
