The revelations of mass graves of civilians and torture chambers in newly liberated Izyum confirm ISW’s previous assessments that the Bucha atrocities were not isolated war crimes but rather a microcosm of Russian atrocities throughout Russian-occupied areas. The Ukrainian General Staff published images on September 16 showing a mass burial site in Izyum, Kharkiv Oblast and noting that Ukrainian President Volodymyr Zelensky said that the site contained more than 400 bodies showing signs of torture and brutality.

Ukrainian forces are continuing counteroffensive operations in eastern Ukraine, increasingly pressuring Russian positions and logistics lines in eastern Kharkiv, northern Luhansk, and eastern Donetsk Oblasts. Russian sources reported that Ukrainian forces are continuing ground operations southwest of Izyum, near Lyman, and on the east bank of the Oskil River, reportedly compelling Russian forces to withdraw from some areas in eastern Ukraine and reinforce others. Russian forces in eastern Ukraine will likely struggle to hold their defensive lines if Ukrainian forces continue to push farther east.

Wagner Group financier Yevgeny Prigozhin is being established as the face of the Russian “special military operation” in Ukraine. Prigozhin gave a recruitment speech on September 14 announcing that Russian prisoners have been participating in the war since July 1 when they were instrumental in seizing the Vuhlehirska Thermal Power Plant. A Russian milblogger noted that Prigozhin is introducing a “Stalinist” method that allows the Kremlin to avoid ordering a general mobilization that could ignite social tensions in Russian society. Milbloggers have been consistently praising Prigozhin’s success in Ukraine and some even said that he should replace the Russian Defense Minister Sergey Shoigu, whom milbloggers and Kremlin pundits blame for the Russian defeat around Kharkiv Oblast. Russian military correspondent and milblogger Maksim Fomin (alias Vladlen Tatarsky) claimed to have spoken to Prigozhin about the situation on the Ukrainian-Russian border after the withdrawal of Russian forces in the area. The Prigozhin-Fomin meeting, if it occurred, could indicate that the Kremlin is attempting to address milbloggers’ months-long complaints that the Russian Defense Ministry did not hear their criticism highlighting the ineffectiveness of Russian higher command. Prigozhin is Putin’s close confidant, and his developing relationship with milbloggers may help retain milblogger support for the Kremlin’s war effort while scapegoating Shoigu and the Russian Defense Ministry for the defeat around Kharkiv Oblast. ISW previously assessed that the Kremlin has changed its information approach to address the demands of the Russian milbloggers and nationalists’, suggesting that Putin seeks to win back the critical milblogger community alienated by Russian failures.

The Kremlin acknowledged its defeat in Kharkiv Oblast, the first time Moscow has openly recognized a defeat since the start of the February 2022 invasion of Ukraine. Kremlin officials and state media propagandists are extensively discussing the reasons for the Russian defeat in Kharkiv Oblast, a marked change from their previous pattern of reporting on exaggerated or fabricated Russian successes with limited detail. The Kremlin never admitted that Russia was defeated around Kyiv or, later, at Snake Island, framing the retreat from Kyiv as a decision to prioritize the “liberation” of Donbas and the withdrawal from Snake Island as a “gesture of goodwill.” The Russian Ministry of Defense (MoD) originally offered a similar explanation for the Russian failure in Kharkiv, claiming that Russian forces were withdrawing troops from Kharkiv Oblast to regroup, but this false narrative faced quick and loud criticism online. The Kremlin’s acknowledgment of the defeat is part of an effort to mitigate and deflect criticism for such a devastating failure away from Russian President Vladimir Putin and onto the Russian Ministry of Defense (MoD) and the uniformed military command.

Ukraine’s southern counteroffensive is continuing to have significant impacts on Russian morale and military capabilities in southern Ukraine. Satellite imagery of known Russian positions in Kyselivka, 15km northwest of Kherson City, shows that all but four Russian vehicles have departed from previous forward positions, consistent with rumors that Donetsk People’s Republic (DNR) troops have abandoned Kyselivka and moved back towards the Dnipro River. Kyselivka is an operationally significant location for Russian forces around Kherson City because it is the last major settlement along both the E58 highway and a railway line between current Ukrainian positions and Chornobaivka, the outermost part of Kherson City. The apparent withdrawal of Russian troops from this position may compromise the Russians’ ability to defend the northwestern outskirts of Kherson City and suggests that Russian troops in this area perceive an imminent threat to their positions. Spokesperson for Ukraine’s Southern Operational Command, Natalya Humenyuk, stated on September 12 that Russian forces located along the right bank of the Dnipro River in Kherson Oblast are attempting to negotiate for surrender under the auspices of international law. Ukrainian operations in Kharkiv Oblast are unlikely to have had such a dramatic psychological effect on Russian troops this far south, and both the withdrawal of troops from forward positions in Kyselivka and reports of surrender negotiations are indicators that Ukrainian counteroffensives in the south are progressing in a significant way, even if visibility on this axis is limited by the shift in focus to Kharkiv.

Ukrainian forces have inflicted a major operational defeat on Russia, recapturing almost all Kharkiv Oblast in a rapid counter-offensive. The Ukrainian success resulted from skillful campaign design and execution that included efforts to maximize the impact of Western weapons systems such as HIMARS. Kyiv’s long discussion and then an announcement of a counter-offensive operation aimed at Kherson Oblast drew substantial Russian troops away from the sectors on which Ukrainian forces have conducted decisive attacks in the past several days. Ukraine’s armed forces employed HIMARS and other Western systems to attack Russian ground lines of communication (GLOCs) in Kharkiv and Kherson Oblasts, setting conditions for the success of this operation. Ukrainian leaders discussed the strikes in the south much more ostentatiously, however, successfully confusing the Russians about their intentions in Kharkiv Oblast. Western weapons systems were necessary but not sufficient to secure success for Ukraine. The Ukrainian employment of those systems in a well-designed and well-executed campaign has generated the remarkable success of the counter-offensive operations in Kharkiv Oblast. The Ukrainian recapture of Izyum ended the prospect that Russia could accomplish its stated objectives in Donetsk Oblast.

The Ukrainian counteroffensive in Kharkiv Oblast is routing Russian forces and collapsing Russia’s northern Donbas axis. Russian forces are not conducting a controlled withdrawal and are hurriedly fleeing southeastern Kharkiv Oblast to escape encirclement around Izyum. Russian forces have previously weakened the northern Donbas axis by redeploying units from this area to Southern Ukraine, complicating efforts to slow the Ukrainian advance or at minimum deploy a covering force for the retreat. Ukrainian gains are not confined to the Izyum area; Ukrainian forces reportedly captured Velikiy Burluk on September 10, which would place Ukrainian forces within 15 kilometers of the international border. Ukrainian forces have penetrated Russian lines to a depth of up to 70 kilometers in some places and captured over 3,000 square kilometers of territory in the past five days since September 6 – more territory than Russian forces have captured in all their operations since April.

Ukrainian forces have captured an estimated 2,500 square kilometers in Kharkiv Oblast in the Kharkiv area counteroffensive as of September 9. Ukrainian President Volodymyr Zelensky and Ukrainian Commander-in-Chief Valery Zaluzhnyi stated on September 8 that Ukrainian forces liberated over 1,000 square kilometers between September 1-8 – a day before Ukrainian forces reached the southern approach to Kupyansk and the Oskil River on September 9. Ukrainian forces are likely clearing pockets of disorganized Russian forces caught in the rapid Ukrainian advance to Kupyansk, Izyum, and the Oskil River, given the influx of observed pictures of Russian prisoners of war in the past 48 hours. Ukrainian forces may collapse Russian positions around Izyum if they sever Russian ground lines of communication (GLOCs) north and south of Izyum. Ukrainian forces continued to advance on Kupyansk and towards Izyum on September 9, and are undertaking measures to isolate the Russian Izyum grouping of forces. If Ukrainians are successful in severing the Russian GLOCs, then they will have an opportunity to create a cauldron around Izyum and collapse a major portion of the Russian positions in northeastern Ukraine.

Ukrainian successes on the Kharkiv City-Izyum line are creating fissures within the Russian information space and eroding confidence in Russian command to a degree not seen since a failed Russian river crossing in mid-May. Ukrainian military officials announced that Ukrainian forces advanced 50km deep into Russian defensive positions north of Izyum on September 8, but the Russian Ministry of Defense (MoD) notably did not issue any statement regarding Ukrainian advances in Kharkiv Oblast. Ukrainian successes and the Russian MoD’s silence prompted many Russian milbloggers to criticize and debate Russian failures to retain control over the city of Balakliya, approximately 44km northwest of Izyum. Some milbloggers claimed that Russian forces fully or partially withdrew from Balakliya in good order, while others complained that Ukrainian forces beat Russian forces out of the settlement. Others noted that Rosgvardia units operating in the area did not coordinate their defenses or have sufficient artillery capabilities to prevent Ukrainian counterattacks in the region. Milbloggers warned about an impending Ukrainian counteroffensive northwest of Izyum for days prior to Ukrainian advances, and some milbloggers noted that Russian command failed to prepare for “obvious and predictable” Ukrainian counteroffensives. Others noted that Ukrainian forces have “completely outplayed” the Russian military command in Balakliya, while others encouraged readers to wait to discuss Russian losses and withhold criticism until Russian forces stabilize the frontlines.
