Ukrainian forces have conducted a sustained counteroffensive north of Lyman since May 2026 under Operation Vivaldi, retaking 150–240 square kilometers and eliminating the Russian salient that threatened encirclement of the city. This has pushed Russian units back toward the Zherebets River, disrupted supply lines for the 20th and 25th Combined Arms Armies, and delayed Moscow’s incremental advances aimed at using Lyman as a stepping stone toward Sloviansk and Kramatorsk. Confirmed Ukrainian gains include Serednie and multiple settlements, with drone interdiction further constraining Russian logistics and maneuver. Russian forces continue localized offensive operations in the Lyman direction but recorded no verified advances in mid-September, while Ukrainian commanders have reinforced the sector with experienced units. These battlefield shifts, verified through ISW mapping and open-source reporting, form the primary driver of trader assessments on capture timelines, with resolution tied to control of the Lyman railroad station. Ongoing attritional fighting and potential for further Ukrainian exploitation remain key variables through late 2026.
