The tactical situation in Verbove remains unclear amid continued Ukrainian offensive operations in western Zaporizhia Oblast on September 25. The Ukrainian General Staff reported that Ukrainian forces continued offensive operations in the Melitopol (western Zaporizhia Oblast) direction and offensive assaults in the Bakhmut direction, inflicting losses on Russian manpower and equipment and depleting Russian forces along the entire front line. Russian sources claimed that Ukrainian forces reached northern Verbove (18km southeast of Orikhiv) but that Russian forces pushed them back to their original positions. Russian sources have yet to directly address a claim from a source reportedly affiliated with the Russian Airborne (VDV) Forces that Ukrainian forces control half of Verbove as of September 24.
Ukrainian forces have adapted. Ukraine’s military decision-making is sound. Now is not the time for Western doubt but for the West to embrace Ukraine’s way of war and commit to sustaining Ukraine’s initiative on the battlefield.
Elements of three Russian divisions are actively defending against Ukrainian assaults around the Ukrainian salient in the Orikhiv area in western Zaporizhia Oblast. Elements of the Russian 42nd Motorized Rifle Division (58th Combined Arms Army, Southern Military District) are deployed and are defending at the southernmost point of the Ukrainian penetration and are engaging Ukrainian forces in Novoprokopivka (13km south of Orikhiv). Elements of the Russian 76th Air Assault Division deployed to the Ukrainian salient’s western flank near Kopani (11km southwest of Orikhiv) towards Robotyne (10m south of Orikhiv) and are counterattacking there. Elements of the 7th Air Assault Division are deployed on the Ukrainian salient‘s eastern flank near the Verbove-Novopokrovka line and are counterattacking there. Sources affiliated with the Russian Airborne (VDV) Forces report that the 56th Air Assault Regiment (7th Air Assault Division) is deployed about 5km north of Verbove near Novofedorivka.
ISW is now prepared to assess that Ukrainian forces have broken through Russian field fortifications west of Verbove in western Zaporizhia Oblast. These fortifications are not the final defensive line in Russia’s defense in depth in western Zaporizhia Oblast, but rather a specific series of the best-prepared field fortifications arrayed as part of a near-contiguous belt of an anti-vehicle ditch, dragon's teeth, and fighting positions about 1.7 - 3.5 km west of Verbove.
Ukrainian Tavriisk Group of Forces Commander Brigadier General Oleksandr Tarnavskyi stated in an interview with CNN published on September 23 that Ukrainian forces achieved a “breakthrough” on the left flank near Verbove and that Ukrainian forces continue advancing. Combat footage posted on September 22 shows a destroyed Ukrainian Mine-Resistant Ambush Protected (MRAP) and BMP-2 operating slightly beyond Russia’s fighting positions trench line near Verbove, indicating continued Ukrainian progress in deploying more heavy equipment beyond Russia’s triune belt of the anti-vehicle ditch, dragon’s teeth, and fighting positions. Commercially available satellite imagery indicates that Ukrainian forces have brought heavy equipment closer to Verbove over the past 96 hours in a manner consistent with Tarnavskyi’s statement. The Wall Street Journal reported on September 21 that Ukrainian forces achieved a “limited breakthrough” west of Verbove citing an unnamed Ukrainian Air Assault Forces officer.
Ukrainian forces carried out drone and cruise missile strikes on occupied Crimea and significantly damaged the Russian Black Sea Fleet (BSF) Command headquarters in Sevastopol on September 22. The Ukrainian Armed Forces Center for Strategic Communications (StratCom) stated that Ukrainian forces launched a successful strike on the Russian BSF Command headquarters in Sevastopol, Crimea on September 22. Russian sources claimed that Ukrainian forces used Storm Shadow cruise missiles to conduct the strike, and social media footage of the headquarters indicates significant damage to the building. The Russian Ministry of Defense (MoD) claimed that Russian air defenses shot down five Ukrainian missiles and acknowledged that the Ukrainian strike damaged a building of BSF Command headquarters. Russian sources claimed that Ukrainian forces launched a drone strike preceding the missile strike, and the Russian MoD claimed that Russian air defenses shot down two Ukrainian drones on the western coast of Crimea on the morning of September 22.
Ukrainian armored vehicles are operating beyond the final line of the Russian defensive layer that Ukrainian forces in western Zaporizhia Oblast are currently penetrating, although ISW is not yet prepared to assess that Ukrainian forces have broken fully through this Russian defensive layer. Geolocated footage posted on September 21 indicates that Ukrainian armored vehicles advanced south of the Russian anti-tank ditches and dragon’s teeth obstacles that are part of a tri-layered defense and engaged in limited combat immediately west of Verbove (18km southeast of Orikhiv). It is unclear if Ukrainian forces retain these positions, however. This is the first observed instance of Ukrainian forces operating armored vehicles beyond the Russian tri-layer defense. The presence of Ukrainian armored vehicles beyond the final line of the current Russian defensive layer indicates that the Ukrainians have secured their breach of the first two lines of this layer sufficiently to operate vehicles through the breach. Ukrainian forces have likely suppressed Russian artillery and other anti-tank systems in the area enough to bring their vehicles forward. The Ukrainian ability to bring armored vehicles to and through the most formidable Russian defenses intended to stop them and to operate these vehicles near prepared Russian defensive positions are important signs of progress in the Ukrainian counteroffensive. Additional geolocated footage published on September 20 and 21 indicates that Ukrainian forces also advanced west and southwest of Verbove.
Ukrainian forces continued offensive actions near Bakhmut and in western Zaporizhia Oblast on September 20. The Ukrainian General Staff stated that Ukrainian forces continued offensive operations and inflicted significant losses on Russian manpower and equipment in the Melitopol (western Zaporizhia Oblast) direction. The Ukrainian General Staff also reported that Ukrainian forces continued offensive actions in the Bakhmut direction and are consolidating in newly secured lines. The UK Ministry of Defense (MoD) assessed that Ukrainian forces secured positions in Klishchiivka (7km southwest of Bakhmut) and Andriivka (10km southwest of Bakhmut) and that Russian redeployments of airborne (VDV) forces from Bakhmut to the Zaporizhia direction have weakened Russian defenses around Bakhmut. ISW had previously observed elements of the 83rd Separate Air Assault Brigade operating in Zaporizhia, although it is unclear how large a proportion of that unit was redeployed from Bakhmut. Ukrainian Eastern Group of Forces Spokesperson Captain Ilya Yevlash stated that Ukrainian forces are preparing defensive positions before Russian forces renew their assaults in the Kupyansk-Lyman direction.
The Russian government quickly signaled on September 19 that Russian peacekeeping forces would not intervene in Azerbaijan’s military operation into Nagorno-Karabakh, despite Russia’s previous security ties to Armenia. The Azerbaijani Ministry of Defense (MoD) announced that Azerbaijani forces began a military operation into Nagorno-Karabakh on September 19. Kremlin Spokesperson Dmitry Peskov claimed that the Russian military is in contact with Armenian and Azerbaijani officials “at the highest level.” Russian Foreign Ministry Spokesperson Maria Zakharova issued a general statement calling on “all sides” to stop the bloodshed, claimed that the Russian peacekeeping contingent in Nagorno-Karabakh continues to fulfil its assigned tasks, and cited the trilateral Russian-Armenian-Azerbaijani agreements signed in 2020 and 2022 as a path toward peace. Russian State Duma Defense Committee Chairman Andrei Kartapolov stated that the Russian peacekeeping contingent does not have the right to use weapons unless directly threatened. A Kremlin-affiliated milblogger claimed that the Russian peacekeeping contingent lacks any protocols on the use of force or rules of engagement in Nagorno-Karabakh, and instead operates on the basis of the November 2020 Nagorno-Karabakh peace agreement.
Ukraine’s liberation of Klishchiivka and Andriivka south of Bakhmut may have degraded the Russian defense in the area south of Bakhmut and could have rendered combat ineffective in as many as three Russian brigades according to Ukrainian military officials. Ukrainian Ground Forces Commander Colonel General Oleksandr Syrskyi stated on September 18 that Klishchiivka (7km southwest of Bakhmut) and Andriivka (10km southwest of Bakhmut) were important elements of the Russian Bakhmut-Horlivka defensive line that Ukrainian forces “breached.” Ukrainian Eastern Group of Forces Spokesperson Captain Ilya Yevlash stated on September 17 that Ukraine’s liberation of Klishchiivka will allow Ukrainian forces to control Russian ground lines of communication (GLOCs) supplying the Russian force grouping in the Bakhmut area — likely referring to Ukrainian forces’ ability to establish fire control over the T0513 Bakhmut-Horlivka highway. ISW is currently unable independently to evaluate the strength and extent of the Russian defensive fortifications in the Bakhmut area, although Russian forces have likely fortified their defense lines near Bakhmut less heavily than they did in southern Ukraine. Russian forces south of Bakhmut are also likely battle-weary from the recent efforts to hold Klishchiivka and Andriivka, and the Ukrainian capture of two settlements defending a key Russian GLOC supporting Bakhmut indicates that these forces will likely struggle to replenish their combat strength and defend against any further Ukrainian offensive activity south of Bakhmut. There are no immediate indications that the liberation of Klishchiivka and Andriivka will portend a higher rate of Ukrainian advance south of Bakhmut, however, and the Russian defense of positions west of the T0513 will likely continue to present challenges for Ukrainian forces in the area.
Ukrainian forces liberated Klishchiivka, south of Bakhmut, on September 17 and continued successful offensive operations elsewhere in the Bakhmut direction. Geolocated footage posted on September 17 shows Ukrainian forces holding up flags in Klishchiivka (7km southwest of Bakhmut). Ukrainian Eastern Group of Forces Spokesperson Captain Ilya Yevlash later confirmed that Ukraine has liberated Klishchiivka, and Ukrainian President Volodymyr Zelensky congratulated the Ukrainian 80th Air Assault Brigade, 5th Assault Brigade, 95th Air Assault Brigade, and National Police “Lyut” Assault Brigade for their role in liberating the settlement. Further geolocated footage posted on September 16 shows that Ukrainian forces have captured positions east of Orikhovo-Vasylivka (10km northwest of Bakhmut). The liberation of Klishchiivka, as well as continued Ukrainian tactical gains northwest of Bakhmut, are tactical gains of strategic significance because they are allowing Ukrainian forces to fix a considerable portion of Russian airborne (VDV) elements in the Bakhmut area, as ISW’s Daniel Mealie discusses in the September 17, 2023 special edition.
