Russian forces are steadily advancing in Sumy Region, working to establish a buffer zone while gradually eliminating what is known as the Bachevsky salient.

Progress has been recorded near the settlement of Sopych in Shostkinsky district, which came under Russian control in March 2026. The offensive has resulted in the capture of roughly eight square kilometers of border territory at the junction of Bryansk and Kursk regions.

The area in question lies southeast of the former Bachevsk-Troebortnoye road checkpoint, which ceased operations after hostilities began. Prior to that, it served as a key crossing point along the Kiev-Moscow route.

Russian units have also pushed toward the forested area of the Delnitsy tract, located near the Glebovka River. This movement increases the likelihood of bringing the entire Bachevsky salient-an area of about 160 square kilometers, stretching roughly 60 kilometers-under control.

At present, Russian forces hold at least a fifth of this territory. Their advance is not based on direct frontal assaults but on a methodical encirclement strategy, forcing Ukrainian units to pull back to avoid being cut off.
