What’s Happening

The Kremlin has reportedly set a new internal deadline of December 31, 2026 for Russian forces to capture the entirety of Donbas, a target that includes the strategic city of Lyman, according to Ukrainian President Volodymyr Zelenskyy. Speaking on June 29, Zelenskyy noted that Moscow has shifted this deadline roughly 15 times since the full-scale invasion began, with the latest postponement pushing the goal back by another year. The Institute for the Study of War (ISW) assessed that Russian President Vladimir Putin claimed elements of his forces have cleared a majority of Lyman and advanced to within 8–9 kilometers of Slovyansk, yet satellite and ground-level evidence indicates Russian troops maintain a presence in only 4.3 percent of Lyman’s urban area as of late June [ISW, Jun 30].

The question of whether Russia can capture Lyman by the end of 2026 hinges on recent tactical reversals. By August 31, Russian milbloggers were increasingly acknowledging Ukrainian counterattacks around Lyman, with Kyiv’s forces reportedly striking from Ridkodub and Stavky north of the city and attempting to cut off a Russian salient northwest of Lyman. A Ukrainian brigade spokesperson reported on August 29 that Russian forces are accumulating personnel and equipment for intensified offensive operations in the Lyman direction, but noted a growing reliance on foreign recruits to fill ranks depleted by months of attritional warfare. The ISW observed that these Ukrainian counteroffensives have liberated several strongholds near Katerynivka, complicating Moscow’s ability to consolidate gains ahead of winter [ISW, Sep 01].

The structural factor that will determine whether a Russia capture Lyman scenario materializes by December 31, 2026 is the pace of force generation on both sides. Deputy Head of the Ukrainian Presidential Office Pavlo Palisa stated on August 29 that Russia’s political leadership has ordered its military to intensify offensive actions in the Lyman direction, yet the Kremlin’s repeated deadline postponements—now stretching into a third year—signal persistent operational shortfalls. Analysts caution that while Russian forces have made incremental gains northeast of Slovyansk, their ability to seize Lyman outright depends on sustaining offensive momentum through the autumn mud season and winter, a period that has historically favored defenders. Ukrainian counterattacks around the city’s northern and southern flanks suggest that the battle for Lyman remains fluid, with neither side holding a decisive advantage as of early September [Ukrainska Pravda, Aug 31].
