Russian forces have made a stealthy incursion into Kostyantynivka, a strategic city in eastern Ukraine, sparking concerns that the wider Donbas region could soon fall under their control. This development marks a significant escalation of the conflict, as Kostyantynivka serves as a crucial gateway to Ukraine's last remaining strongholds in the east – Kramatorsk and Sloviansk.
The city is now described by Ukrainian soldiers on the ground as effectively a 'grey zone', where neither side holds definitive control. Reports from the BBC suggest that Russian forces, estimated to be approximately 130-strong, are slowly accumulating more personnel within the city, fuelling fears of an imminent breakthrough. If Kostyantynivka falls, it would clear the way for Russian forces to advance towards the Ukrainian strongholds, which have been a primary objective for Moscow since the full-scale invasion began.
Despite Moscow's claims of rapid advances and encirclement of Ukrainian units, Kyiv has denied these assertions. Brigadier General Oleksandr Bakulin, commander of Ukraine's 19th Corp responsible for defending the area, insists that 'the situation remains under control' and 'the enemy has no success'. However, anonymous Ukrainian officers have suggested that while the situation is not as critical as Russia portrays, it appears more serious than publicly acknowledged by Ukrainian officials.
The urban environment of Kostyantynivka presents a challenging battleground, with numerous buildings and summer foliage providing ample cover for soldiers. Both sides are heavily reliant on drone operations, with Ukrainian forces using them to detect and attack movements in what they describe as a 'kill zone'. Conversely, Russian drone pilots have prioritised destroying Ukrainian drone launch sites to provide their infantry with crucial breathing room during assaults on Ukrainian positions.
The tactics employed by Russian forces in Kostyantynivka mirror strategies used in the capture of other eastern Ukrainian cities. These involve advancing along the flanks to encircle the city and sever vital supply routes, aiming to cut off the defending forces. The UK's Foreign, Commonwealth & Development Office (FCDO) continues to advise against all travel to Ukraine due to the ongoing conflict and advises British nationals already there to leave if it is safe to do so.
