Russian forces may be abandoning efforts at a wide encirclement of Ukrainian troops along the Izyum-Slovyansk-Debaltseve line in favor of shallower encirclements of Severodonetsk and Lysychansk. Russian forces likely control almost all of Rubizhne as of May 12 and have likely seized the town of Voevodivka, north of Severdonetsk.[1] They will likely launch a ground offensive on or around Severodonetsk in the coming days. The relative success of Russian operations in this area combined with their failure to advance from Izyum and the notable decline in the energy of that attempted advance suggest that they may be giving up on the Izyum axis. Reports that Russian forces in Popasna are advancing north, toward Severodonetsk-Lysychansk, rather than east toward the Slovyansk-Debaltseve highway, support this hypothesis.
It is unclear if Russian forces can encircle, let alone capture, Severodonetsk and Lysychansk even if they focus their efforts on that much-reduced objective. Russian offensives have bogged down every time they hit a built-up area throughout this war, and these areas are unlikely to be different. Continued and expanding reports of demoralization and refusals to fight among Russian units suggest that the effective combat power of Russian troops in the east continues to be low and may drop further. If the Russians abandon efforts to advance from Izyum, moreover, Ukrainian forces would be able to concentrate their efforts on defending Severodonetsk-Lysychansk or, in the worst case, breaking a Russian encirclement before those settlements fall.
The Ukrainian counteroffensive around Kharkiv is also forcing the Russian command to make hard choices, as it was likely intended to do. The UK Ministry of Defense reports that Russian forces pulled back from Kharkiv have been sent toward Rubizhne and Severodonetsk but at the cost of ceding ground in Kharkiv from which the Russians had been shelling the city.[2] The counteroffensive is also forcing Russian units still near the city to focus their bombardment on the attacking Ukrainian troops rather than continuing their attacks on the city itself. The Ukrainian counteroffensive near Kharkiv is starting to look very similar to the counteroffensive that ultimately drove Russian troops away from Kyiv and out of western Ukraine entirely, although it is too soon to tell if the Russians will make a similar decision here.
Russian forces likely seized Rubizhne and made marginal advances to Voevodivka, a suburb of Severodonetsk. Luhansk Oblast Administration Head Serhiy Haidai said that Ukrainian forces partially control Rubizhne, but Ukrainian servicemen claimed that Ukrainian forces only have access to the T1302 highway exit on the settlement's western outskirts.[8] The Luhansk People's Republic and Chechen units entered the Zorya Chemical Plant between Rubizhne and Voevodivka on May 11. Fighting was ongoing at the plant as of May 12.[9] Ukrainian forces destroyed a second Russian pontoon bridge in the vicinity of Bilohorivka, approximately 13 km from Rubizhne, on May 11 to slow the Russian encirclement of the settlement from the northwestern direction.[10] Severodonetsk Regional State Administration Head Oleksandr Stryuk confirmed that Russian forces seized Voevodivka on May 12, contradicting the Ukrainian General Staff's assertion that the Russian offensive was unsuccessful.[11] Russian forces will likely launch a ground offensive on Severodonetsk in the coming days once they fully secure Voevodivka.
Russian authorities additionally continued occupation activity in
Mariupol. Advisor to the Mayor of Mariupol Petro Andryushchenko stated that Russian forces have established filtration checkpoints throughout the entire city to further consolidate control.[17] Andryushchenko noted that occupation authorities may hold a referendum for Mariupol to join Russia as soon as May 15.
The Ukrainian Ministry of Defense stated that the Russian grouping on
Snake Island is trying to improve its position on the island in an effort to block Ukrainian maritime communications and capabilities in the northwestern Black Sea, particularly toward Odesa.[24] The Ukrainian General Staff noted that Russian forces have built up their air defense system in Western Crimea in a likely attempt to provide air cover for naval activities in the northwestern Black Sea.
