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.

The Kremlin is rushing resources to the Kharkiv City-Izyum line in an attempt to halt Ukrainian advances after Ukrainian forces achieved remarkable operational surprise.

The Russian Ministry of Defense (MoD) and Kremlin wires published footage of Russian military convoys reportedly en route to reinforce Kupyansk, Izyum, and the general Kharkiv direction but did not acknowledge Ukrainian successes in the area. While Russian milbloggers largely welcomed the reports of reinforcements, some criticized the Kremlin for first relocating units away from the Kharkiv City-Izyum line, only to deploy them again to the same location. Russian forces have been redeploying out of southern Kharkiv Oblast to reinforce Donetsk Oblast and the Southern Axis to address the threat of a Ukrainian counteroffensive in Kherson Oblast and to resume offensive operations west of Donetsk City for several weeks. The successful Ukrainian counteroffensive is upending the Kremlin’s effort to make Izyum an economy of force area. Some milbloggers also noted that September 10 will be a decisive day if Russians are unable to generate reserves and capable command in time.

N Korea, Russia Sign Mutual Defence Deal as Kim Pledges Support on Ukraine

The two countries have been allies since North Korea's founding after World War II, and have drawn even closer after Russia's invasion of Ukraine in 2022 isolated Putin on the global stage.

The Kremlin is refusing to publicly address Ukrainian successes in Kharkiv Oblast, but the counteroffensive likely prompted Russian President Vladimir Putin to convene a meeting with top Russian security and political officials on September 9.

The Kremlin did not discuss the topic of the security council meeting, and the Kremlin’s Spokesperson Dmitry Peskov stated that the Kremlin will not comment on the “situation around Balakliya and other events in the special operation zone.” Peskov directed all inquiries regarding the issue to the Russian MoD.

Ukraine’s counteroffensive operation in Kherson Oblast to degrade Russian forces on the Southern Axis is continuing simultaneously with Ukrainian operations on the Kharkiv City-Izyum line. Ukrainian forces are continuing to target Russian pontoon and ferry crossings daily, which indicates a long-term commitment to consistently destroying re-emerging Russian GLOCs. Ukrainian forces are maintaining a strict operational silence in southern Ukraine, which may appear as if Ukrainian forces are not advancing. Ukrainian forces are also likely operating in several directions in Kherson Oblast.
