**Deck**: Russian forces have made incremental advances across three axes in Ukraine’s Sumy region near Hlukhiv, Khotin and Krasnopillya over recent weeks, pushing into forests, treelines and villages north of the regional capital. The slow, grinding progress opens a new line of pressure on Ukraine’s overstretched defenses and raises hard questions about Kyiv’s capacity to hold a long northern front.

As much of the world watches the front lines in eastern and southern Ukraine, Russian troops are quietly testing a different seam: the northern approaches to Sumy. Over the past several weeks, Russian forces have intensified assaults along three directions — Hlukhiv, Khotin and Krasnopillya — making incremental gains in forests, treelines and parts of villages that could, over time, complicate Ukraine’s wider defensive posture.

On the Hlukhiv axis, Russian units have advanced in three separate areas, according to battlefield reporting on 27 June. To the south, they pushed north of large forests that straddle the international border, capturing a series of treeline positions southeast of Ulanove. Further north, infiltration operations are underway in an attempt to link scattered footholds. These kinds of micro‑advances, while modest on a map, provide staging areas for future pushes and make it harder for Ukrainian forces to maintain stable lines.

West of there, along the Khotin direction, Russian troops are reported to have gained a foothold in the northeastern part of Korchakivka. They have also improved positions in the adjacent forest to the east and are trying to work their way toward the northern outskirts of the village of Khotin itself. Control of these forest belts matters out of proportion to their apparent size: they offer concealment from drones, covered routes for infantry, and launchpads for raids toward deeper Ukrainian territory.

Further south, in the Krasnopillya sector, Russian forces have continued assault operations in several areas, capturing forests east of Ryasne and then securing the eastern and southeastern parts of the village. Fighting reportedly continues for western Ryasne, indicating a dynamic and contested front. Additional Russian attacks are targeting villages and positions along this axis, with the apparent goal of widening the corridor under their control.

For residents of rural Sumy oblast, many of whom have already endured shelling and periodic incursions since the start of the full‑scale invasion, the renewed ground pressure brings fresh uncertainty. Villages near the tree lines now in play risk becoming staging grounds or buffer zones, with the attendant threat of artillery fire, fortification building, and potential evacuations. Roads that once served mainly farmers and local traders take on new importance as resupply routes — and, if cut, as choke points.

Strategically, the Russian push in Sumy forces Kyiv to make difficult resource decisions. Ukraine must decide how many troops, artillery pieces and air‑defense assets to deploy along a long northern border where advances are currently tactical in scale, while still holding critical fronts around Kharkiv, Donetsk and the south. Every battalion sent to reinforce Sumy is a battalion not available for counter‑attacks elsewhere. For Russia, even small territorial gains can achieve outsized effect if they stretch Ukrainian defenses thin, absorb attention, and threaten to open new directions for a future offensive.

The pattern emerging across the three Sumy axes suggests that Moscow is less focused, for now, on rapid breakthroughs than on establishing a series of interlocking positions in forests and villages that can be expanded when conditions are favorable. That kind of salami‑slice approach is harder to headline than a major city falling, but over months it can redraw local realities and set the stage for deeper operations.

The key signals to watch next are whether Russian forces begin to deploy heavier armor and logistics infrastructure into the newly captured zones, whether Ukraine moves to fortify a secondary defensive line deeper in Sumy oblast, and if any of the contested villages tip decisively into one side’s control. A noticeable increase in evacuations or shelling reports from communities behind the current contact line would indicate that this northern pressure is transitioning from probing to something more ambitious.
