Russian forces have likely abandoned efforts to complete a single large encirclement of Ukrainian forces in eastern Ukraine and are instead attempting to secure smaller encirclements—enabling them to make incremental measured gains. Russian forces are likely attempting to achieve several simultaneous encirclements of small pockets of Ukrainian forces in Donetsk and Luhansk oblasts: the broader Severodonetsk area (including Rubizhne and Lysychansk), Bakhmut-Lysychansk, around Zolote (just northeast of Popasna), and around Ukrainian fortifications in Avdiivka. Russian forces have begun steadily advancing efforts in these different encirclements daily but have not achieved any major “breakthroughs” or made major progress towards their stated objectives of securing the Donetsk Oblast borders or seizing all of Donbas. Luhansk Oblast Administration Head Serhiy Haidai reported that Ukrainian forces only controlled approximately 10 percent of Luhansk Oblast as of May 15 (compared to 30 percent prior to the full-scale Russian invasion on February 24, 2022). Russian forces have secured more terrain in the past week than efforts earlier in May. However, they have done so by reducing the scope of their objectives—largely abandoning operations around Izyum and concentrating on key frontline towns: Russian performance remains poor.
Russian nationalist figures are increasingly criticizing the failures of Russia’s “special military operation” in Ukraine and are calling for further mobilization that the Kremlin likely remains unwilling and unable to pursue in the short term. The All-Russian Officers Assembly, an independent pro-Russian veterans’ association that seeks to reform Russian military strategy, called for Russian President Vladimir Putin and the Kremlin to declare war on Ukraine and introduce partial mobilization in Russia on May 19. The Assembly said that Russia’s “special military operation” failed to achieve its goals in three months, especially after the failed Siverskyi Donets River crossings. ISW previously assessed that the destruction of nearly an entire Russian battalion tactical group (BTG) during a failed river crossing on May 11 shocked Russian military observers and prompted them to question Russian competence. The Assembly’s appeal called on Putin to recognize that Russian forces are no longer only “denazifying” Ukraine but are fighting a war for Russia’s historic territories and existence in the world order. The officers demanded that the Kremlin mobilize all regions bordering NATO countries (including Ukraine), form territorial defense squads, extend standard military service terms from one year to two, and form new supreme wartime administrations over Russia, the Donetsk and Luhansk People’s Republics (DNR and LNR), and newly occupied Ukrainian settlements. The officers also demanded the death penalty for deserters.
Russian forces made only minimal gains in eastern Ukraine on May 22. New reporting confirmed that Russian troops previously recaptured Rubizhne in northern Kharkiv Oblast, on May 19. Russian forces are likely committing additional reinforcements to hold their positions on the west bank of the Siverskyi Donets River in northern Kharkiv—rather than withdrawing across the river to use it as a defensive position—to prevent any further Ukrainian advances to the north or the east that could threaten Russian lines of communication to the Izyum axis. Ukrainian sources additionally confirmed previous Russian-claimed advances around Popasna, and Russian forces likely seek to open a new line of advance north from Popasna to complete the encirclement of Severodonetsk while simultaneously driving west toward Bakhmut, though Russian forces are unlikely to be able to fully resource both lines of advance simultaneously.
Russian forces intensified efforts to encircle and capture Severodonetsk on May 21 and will likely continue to do so in the coming days as efforts on other axes of advance, including Izyum, remain largely stalled. Russian troops in Luhansk Oblast will likely move to capitalize on recent gains made in the Rubizhne-Severodonetsk-Luhansk-Popasna arc to encircle and besiege Severodonetsk—the final Ukrainian strongpoint in Luhansk Oblast. Russian milbloggers are hypothesizing on the success of Russian tactics in the area and have dubbed it the Battle of Severodonetsk—emphasizing that this is the preliminary line of effort in the Donbas theatre.
Russian forces are focusing on digging in and reinforcing defensive positions in Kharkiv and along the Southern Axis in preparation for Ukrainian counteroffensives, while the majority of active offensive operations remain confined to Izyum-Donetsk City arc and especially the Popasna-Severodonetsk area. The Ukrainian General Staff reported that Russian forces are creating secondary defensive lines on the Southern Axis, indicating that the Russian grouping in this area may be preparing for a major Ukrainian counter-offensive and a protracted conflict.
Ukrainian military officials reported that some Russian troops withdrawn from the Kharkiv City axis have redeployed to western Donetsk Oblast on May 19. The Ukrainian General Staff said that 260 servicemen withdrawn from the Kharkiv City axis arrived to replace the significant combat losses that the 107th Motorized Rifle Battalion has taken approximately 20 km southwest of Donetsk City. The Ukrainian Military Directorate (GUR) intercepted a Russian serviceman’s call suggesting that some of the 400 servicemen from the Kharkiv City axis who had arrived elsewhere in Donbas were shocked by the intensity of the fighting there compared with what they had experienced in Kharkiv Oblast.
Russian occupation authorities announced plans to destroy the Azovstal Steel Plant and turn Mariupol into a resort city, depriving Russia of some of the most important economic benefits it hoped to reap by taking the city in the first place. Head of the Donetsk People’s Republic (DNR) Denis Pushilin stated that DNR authorities are planning to level Azovstal after completing its capture. Azovstal was a major element of Mariupol’s economy before the war because of its unique function as a full-cycle metallurgical complex, the 10,000 jobs associated with production at the plant, the billions of dollars of foreign exchange earnings and taxes it generated, and its production output of 7,000 tons of steel, 6 million tons of iron, and 4.5 million tons of rolled metal, according to the Mariupol City Council. Pushilin stated that the DNR intends to rebuild Mariupol to be a “resort city,” while admitting that 60% of the structures in Mariupol have been destroyed to the point where they cannot be rebuilt. The announced plan to turn Mariupol into a center of tourism and leisure following the complete destruction of a major center of economic activity in Mariupol, is indicative of the damage that Russian troops have inflicted on themselves through the destruction of Mariupol. Russia does not need another resort town on the Black Sea. It does need the kind of hard currency that a plant like Azovstal had generated. This announcement epitomizes the kind of Pyrrhic victories Russian forces have won in Ukraine, to the extent that they have won victories at all.
Mariupol defenders trapped in the Azovstal Steel Plant likely surrendered after Ukrainian officials negotiated evacuation measures with the Kremlin. Russian forces began evacuating wounded Ukrainian forces to Russian-occupied settlements in Donetsk Oblast on May 16 after the Russian Defense Ministry proposed the agreement earlier in the day. Ukrainian officials said that they will seek to return the Mariupol defenders to Ukraine in a prisoner exchange and continue to undertake appropriate measures to rescue all Ukrainian servicemen from Azovstal.
Russian forces conducted limited and largely unsuccessful ground offensives along the front line in Ukraine on May 16. The Russian grouping around Kharkiv City is notably trying to hold the border and prevent Ukrainian troops from advancing further north. This activity is different from previous Russian withdrawals from around Kyiv, Chernihiv, and Sumy earlier in the war when the Russians pulled completely back to Russian territory. Russian troops may seek to retain positions in Ukraine and continue artillery strikes on Ukrainian positions in order to prevent Ukrainian forces from getting into tube or rocket-artillery range of the outskirts of Belgorod, a major city in Russia and a key hub of the Russian military effort. The Russians might alternatively hope to conduct a counter-counter-offensive to push back south toward Kharkiv, although such an effort is highly unlikely to succeed.
Russian forces have likely abandoned the objective of completing a large-scale encirclement of Ukrainian units from Donetsk City to Izyum in favor of completing the seizure of Luhansk Oblast. Luhansk Oblast Administration Head Serhiy Haidai said that the Russian military command likely understands that it will not be able to seize Donetsk Oblast but believes that it has the capacity to reach the administrative borders of Luhansk Oblast. His observations are generally consistent with our analysis. The Russian military command will likely prioritize the Battle of Severodonetsk going forward, with some efforts dedicated to disrupting Ukrainian ground lines of communication (GLOCs) in eastern Donetsk Oblast. Russian forces are continuing a coordinated effort to seize Severodonetsk from the north and the south, which would result in a shallower encirclement of Ukrainian troops than originally expected. The failed Russian attempts to cross the Siverskyi Donets River near Kreminna may shift Russian encirclement operations further east, closer to Severodonetsk via Rubizhne, rather than conducting a wider encirclement along multiple axes. Russian forces have also likely been scaling down advances to Slovyansk from Izyum, possibly due to the slow pace of the offensive operation there.
