Don't believe the headlines coming out of Moscow. When Russian General Valery Gerasimov stood before Vladimir Putin and proudly declared that Kostiantynivka had completely fallen, he was playing a dangerous game of political theater. The Kremlin wants you to think the frontlines are collapsing and that the keys to the Donbas have been handed over on a silver platter.
Kyiv shot back immediately, claiming they still fully control the city.
Honestly, both sides are twisting the reality on the ground. The truth is much messier, far more brutal, and reveals a battlefield where neither army has total control. Russia hasn't captured Kostiantynivka outright, but the Ukrainian military isn't exactly throwing a victory parade inside the city center either.
If you want to understand what's actually happening in eastern Ukraine right now, you have to look past the official press releases and focus on the brutal math of attrition.
The Truth About Russia's Supposed Victory
The Institute for the Study of War tracked Russian progress and confirmed that Moscow's forces have infiltrated roughly 37 percent of Kostiantynivka. They've pierced the northern outskirts and cut some major roads leading toward Kramatorsk. But lingering in over a third of a city isn't the same as holding it.
Ukrainian troops are still heavily dug into the city center and the southern districts. They're fighting from cellar to cellar, using heavy drone cover to break up Russian assault groups. The video footage trickling out from local units shows that many of those Russian soldiers raising flags over ruined buildings are small infiltration teams. Often, they're wiped out by Ukrainian drone operators just hours after the cameras stop rolling.
So why did the Kremlin lie so blatantly about total victory?
It's all about optics and domestic pressure. The year 2026 has been an incredibly dark time for the Russian war machine. In April and May alone, Russia suffered a net loss of about 400 square kilometers of territory across the wider front. It was their first monthly net loss of ground in nearly two years. Putin even had to scale back his prized annual military parade out of fear that Ukrainian long-range strikes would hit the capital. The Kremlin desperately needed a win to flash under the noses of its public and Western partners. Kostiantynivka was their chosen sacrificial lamb.
The Horrific Cost of Fifty Meters a Day
The Center for Strategic and International Studies recently crunched the numbers on Russia's current offensive speed. The results are staggering. Around Kostiantynivka, the Russian army is advancing at a pathetic average rate of just 50 meters per day. To put that into perspective, that's slower than the British and French advances during the infamous Battle of the Somme in World War I, which averaged about 80 meters a day.
This isn't modern blitzkrieg. It's a meat grinder.
The human toll backing up these numbers is hard to comprehend. Total Russian battlefield fatalities since 2022 have crossed the 400,000 mark, with total casualties climbing past 1.4 million. In June, Ukrainian forces killed or wounded nearly 40,000 Russian soldiers. When you map that against the tiny slivers of mud and concrete Russia managed to take that month, they lost roughly 1,298 soldiers for every single square kilometer they seized or infiltrated. Just a year prior, that ratio was 68 casualties per kilometer.
Ukraine's casualty-to-infliction ratio has widened to a shocking 8:1 advantage in the first half of this year. They're managing this by relying heavily on AI-enabled strike drones that hunt down Russian armor and infantry before they can even reach the frontline trenches.
How Ukraine is Keeping the Lights On
The biggest headache for the Ukrainian defenders inside Kostiantynivka isn't the Russian infantry; it's logistics. For months, Russian forces have hammered the main supply arteries leading into the city with heavy aerial glide bombs and artillery. The situation got so bad in the southern sectors that Ukrainian troops had to be resupplied almost exclusively by heavy-lift drones.
Lately, the fight has centered on a weighting-material plant near the local railway line. Russian forces have been trying to choke off this final, incredibly dangerous path. Ukrainian forces have countered by deploying remote-controlled unmanned ground vehicles to trundle supplies down the tracks under heavy enemy fire.
It's an apocalyptic way to wage war, but it's working well enough to keep the defensive lines from snapping. Russia tried to offer a brief six-hour ceasefire under the guise of trading fallen soldiers' bodies, but Kyiv saw right through it and refused. These temporary pauses are just tactical breathers designed to let exhausted Russian units stockpile ammunition and rotate fresh bodies into the meat grinder.
The Real Strategy Moving Forward
Let's be real about where this is heading. Kostiantynivka is a ruined husk. The city of 66,000 people is now a wasteland of blackened concrete and cratered roads. Military analysts and local Ukrainian commanders acknowledge that holding the city forever is likely impossible.
But total victory for Russia isn't the objective here anyway.
The Ukrainian military is playing for time. By forcing Russia to bleed out thousands of men and burn through hundreds of armored vehicles for every city block, Ukraine is preserving its forces for the defense of the broader "fortress belt"—the heavily fortified high-ground cities of Druzhkivka, Kramatorsk, and Sloviansk.
Even if Russian troops eventually clear the remaining defenders out of Kostiantynivka's western ruins, they'll inherit a graveyard. They'll be completely exhausted, stripped of their offensive momentum, and facing an uphill climb against massive Ukrainian fortifications on the heights just north of the city.
Keep your eyes on the supply lines running through the Kramatorsk railway corridor. If Ukraine can keep using its drone fleets to disrupt Russian fuel transport and artillery positions behind the lines, they will continue to stretch Russia's manpower to the absolute breaking point, regardless of what the Kremlin claims on Telegram.
