Ukraine’s secret counteroffensive is more successful than we thought

- Ukraine's quiet counteroffensive north of Lyman has produced dramatic results since April
- Now two Russian regiments are in danger of encirclement
- Escape is still likely for the Russians, but their retreat buys time for the Ukrainian defenders of Lyman and nearby Sloviansk
Ukraine secret eastern counteroffensive seems to have been even more successful than some observers reported. It's possible that, in the sector just north of the town of Lyman in eastern Ukraine's Donetsk Oblast, the Ukrainian 3rd Army Corps is just a few kilometers short of encircling two Russian regiments.
That doesn't mean the Russian units can't escape. After all, there isn't a contiguous line of Ukrainian forces—nor a contiguous line of Russian forces for that matter—anywhere along the 1,200-km disputed gray zone that threads across eastern and southern Ukraine.

But the closing pincer around elements of the Russian 2nd and 144th Motor Rifle Divisions could strain the Russians' logistics and compel the Russians to reconsolidate in order to preserve their combat power—by retreating east. That would take a lot of pressure off Lyman and, by extension, also take a lot of pressure off Sloviansk and Kramatorsk, the last two big free cities in Donetsk.
Lyman, which lies 15 km northeast of Sloviansk—the northernmost of the free cities—is the main obstacle between at least six Russian regiments and Sloviansk. The Russians have been inching toward Sloviansk and Kramatorsk from several directions for months now, racing against the coming winter to position forces for a possible siege of the twin cities next year. Winter in Ukraine punishes any attacker by depriving them of the leafy tree canopy that can conceal infiltrating troops during warmer months.
According to the most recent map from analyst and mapper Thorkill, one of the more reliable observers of unit-level action in Ukraine, the Ukrainian 3rd Assault Brigade is just a few kilometers away from linking up with the 60th Mechanized Brigade in or around the village of Kolodyazi.

Galloping advance
If true, that means the 3rd Assault Brigade and adjacent units from the 3rd Army Corps have carried out one of the more successful Ukrainian counteroffensives in memory. In April they first exploited gaps in Russian defenses north of the village of Nove. In May and June they advanced toward the village. In July they captured it.
After that, the attacking Ukrainians kept pushing south into the right flank of a 10-km-by-10-km salient that advancing Russian regiments created as they maneuvered around Lyman from the north, aiming to surround the town instead of directly assaulting it on their way toward Sloviansk.
Leaving their flank exposed, the Russians trying to encircle Lyman found themselves at risk of encirclement, instead. If the 3rd Assault Brigade or 60th Mechanized Brigade—together possessing thousands of troops, on paper—can march through Kolodyazi, they will have closed a ring of loose Ukrainian control around at least two Russian regiments, also with potentially thousands of troops.
Emphasis on loose control. Again, there aren't enough Ukrainian forces on the ground north of Lyman to prevent any "encircled" Russians from retreating back to the east. But that retreat would represent a major victory for the Ukrainian defenders north and east of Sloviansk. "The fall of this salient [north of Lyman] would significantly delay the fall of Lyman," analyst and mapper AMK Mapping predicted.

The Ukrainian counterattacks north of Lyman are now entering their fourth month, as they come closer and closer to cutting off the Russian salient. Two pincers have been formed, which are both dangerously close to cutting the Russians… pic.twitter.com/mu2kZ4S3Jv(@AMK_Mapping_) August 26, 2026
No one expects the Russians to halt their offensive toward Sloviansk and Kramatorsk. But in potentially taking two steps forward and one step back in their northerly march on the free cities, the Russians sacrifice time. Time the Ukrainians can use to stiffen their defenses in Sloviansk and Kramatorsk and evacuate more of the tens of thousands of civilians who remain in the cities despite the constant danger from Russian drones and bombs.
The possible extent of the Ukrainian gains north of Lyman—a 10-km march since April—is impressive given Russia's overall advantage in manpower and firepower in the east. Equally impressive is the operational security, or OPSEC, that cloaked the offensive until now. Sure, there were a few videos of action around Nove that hinted at a major Ukrainian action.
But the units involved exercised surprising discipline, and prevented too much information from leaking. "Someone in the 3rd Corps responsible for [OPSEC] is actually trying to do their job diligently and has quite effectively cut off information," Thorkill noted. The secrecy may have facilitated the Ukrainian advance by delaying any sense of panic among the Russian commanders who are responsible for reinforcing the Lyman salient, but who also tend to ignore bad news as long as possible because they know it could reflect poorly on them.
News of the counteroffensive is now available for all to see, even if official Ukrainian sources have yet to confirm it. That may mean time is running out for the 3rd Army Corps to close its pincer before the Russians retreat or reinforce. AMK Mapping has already seen some evidence of a "partial withdrawal from the most vulnerable positions in the salient.
