On 10 May 2024, the Russian Armed Forces began an offensive operation in Ukraine's Kharkiv Oblast, shelling and attempting to breach the defenses of the Ukrainian Armed Forces in the direction of Vovchansk and Kharkiv. The Guardian reported that the offensive led to Russia's biggest territorial gains in 18 months. By early June the Russian offensive stalled, with The Guardian reporting that the situation on the frontline had been "stabilized." Ukrainian forces then began small-scale counterattacks, which reportedly recaptured a settlement on 19 June.

The Russian armed forces have also launched raids into Sumy Oblast and other segments of Kharkiv Oblast, in an effort to draw Ukrainian resources away from the main offensive in Kharkiv. Similarly, Ukrainian forces have launched raids into Belgorod Oblast, while some western analysts attribute the 2024 Kursk offensive as a diversion from Kharkiv.

Background

On February 24, 2022, the opening day of the Russian invasion of Ukraine, 20,000 Russian soldiers commenced an offensive operation south from Belgorod Oblast to capture Kharkiv, Ukraine's second largest city. Throughout February, Russian forces captured Vovchansk, before continuing south to Shevchenkove, and Balakliia, Izium. It has been speculated that Russian operations near these cities were initially meant to cut off Kharkiv from the south and southeast, thus separating it from combat-ready Ukrainian units in the Donbas and ensuring its capture by the Russian forces advancing from the city's north, though Russian forces would later abandon their plans to capture Kharkiv. For three days Kharkiv was the site of street fighting until Russian forces withdrew on February 28 under threat of being encircled in the city. Ukrainian forces launched a major counteroffensive in Kharkiv Oblast in late 2022. As a result, Ukrainian control was restored over most of Kharkiv Oblast, with the exception of a small portion in the northeast between the border with Luhansk Oblast and the Oskil river.

Ethnically Russian pro-Ukrainian militias, the Russian Volunteer Corps and Freedom of Russia Legion performed cross-border raids into Kursk and Belgorod in 2023 and again later in 2024. Kremlin Press Secretary Dmitry Peskov and Russian Foreign Minister Sergey Lavrov repeatedly threatened to attack Kharkiv Oblast and establish a buffer zone to protect Russia's border in response. During the first months of 2024, reports appeared that the Russian army was rebuilding its forces in the north to launch a new offensive in the direction of Kharkiv later that year. On 8 May 2024, the governor of Kharkiv Oblast, Oleh Syniehubov, reported a large gathering of Russian forces north of the region. The secretary of the National Security and Defense Council of Ukraine, Oleksandr Lytvynenko, subsequently said that over 50,000 Russian soldiers had been deployed to the border.

According to the Ukrainian military journalist , the Ukrainian command became aware of the Russian plan to launch an offensive into the Kharkiv region and the composition of the troops involved no later than the beginning of April. At the end of April, the Ukrainian forces in the area were brought to full combat readiness.

Offensive

Up to 4–5 Russian infantry battalions from a newly created force launched an armored ground attack across the state border around 05:00 on 10 May, opening a new front in the war. Russian forces launched two limited offensive efforts, one in the direction of Lyptsi and one in the area of Vovchansk. Ukraine's armed forces urged residents of northern Kharkiv Oblast to evacuate.

A senior Ukrainian military source told Reuters that Russian forces were aiming to advance up to 10 kilometers into Ukrainian territory in order to establish a buffer zone. Ukrainian officials did not believe that Russia was capable of launching an operation to capture Kharkiv, Ukraine's second-largest city.

Vovchansk front On 10 May, the border city of Vovchansk was subjected to "massive shelling" by artillery and guided aerial bombs, and residents were evacuated. Fighting was reported in the villages of , Hatyshche, and , and Russian bloggers claimed that these three villages had come under Russian control.

In a 11 May briefing, the Russian defence ministry claimed that its forces had taken Pletenivka and Ohirtseve. According to the ISW, geolocated footage published on 11 May indicated Ohirtseve had indeed come under Russian control.

The same day, Russian military bloggers claimed that Russian forces had captured the village of Tykhe and were trying to advance into Vovchansk, but the ISW said it had not observed evidence to verify these claims.

The Russian Ministry of Defence claimed on 12 May that its forces had captured the village of Hatyshche. ISW assessed that Hatyshche, Pletenivka and Tykhe had come under Russian control by 12 May. Certain Russian and Ukrainian sources claimed that combat was ongoing in Vovchansk, though a Ukrainian military spokesman denied reports that Russian forces had entered the city.

On 13 May, Russian forces advanced into Vovchansk and managed to capture the located north of the city. A shoe factory in the north of Vovchansk was captured in the morning and Russian troops advanced into the center of Vovchansk up to the northern (right) bank of the river Vovcha by the evening, according to Russian milbloggers. The General Staff of the Ukrainian Armed Forces said that Russian forces had achieved "tactical success" in Vovchansk.

On 14 May, Russian forces continued to make gains within Vovchansk, and advanced into central . The Russian ministry of defense claimed that its forces had fully secured the village, which the ISW said was consistent with geolocated evidence.

Russian advances near Vovchansk continued on 15 May. Russian milbloggers claimed that Russian forces had taken control of Starytsia and were attacking near Izbytske and Buhruvatka. The next day, Russian forces advanced within northern Vovchansk and made marginal gains in northeastern Starytsia, while continuing offensive operations near Starytsia and Pletenivka. A Ukrainian sergeant operating near Vovchansk told the Wall Street Journal on 17 May that Russian forces were in control the northern half of the city, although the ISW had not observed evidence that the entire portion of Vovchansk north of the Vovcha River had come under Russian control.

The Russian ministry of defense claimed on 18 May that the Russian army had captured Zybyne, and also claimed to have advanced near Buhruvatka and repelled Ukrainian counterattacks near Tykhe.

Russian forces made advances in Vovchansk on 19 May, namely in the northeast, reportedly reaching the Vovcha River. Russian milbloggers claimed on 19 May that Russian forces seized Starytsia and Buhruvatka. The Russian Ministry of Defense claimed that Russian forces repelled Ukrainian counterattacks in Vovchansk and near Starytsia on 21 May.

Russian milbloggers claimed the same day that a Russian force had crossed the Vovcha River. The Institute for the Study of War assessed that Russia probably maintained a small infantry foothold across the river, but with no vehicles or artillery.

Lyptsi front On 10 May, Russian forces reportedly captured the villages of Krasne, Borysivka, Strilecha, and Pylna. According to Ukrainian military journalist Yuri Butusov, this captured border area had been a "gray zone" behind the Ukrainian defensive line with no Ukrainian military presence, with the exception of Strilecha. Syniehubov also referred to the affected villages as a "gray zone", claiming that "the Ukrainian armed forces have not lost a single meter". According to DeepStateMap.Live analysts, citing confidential sources, Russian forces had occupied the village of Pylna several days before 10 May, but poor communication within the Ukrainian military had prevented any action from being taken.

The same day, fighting was reported in the villages of Hoptivka, Morokhovets, and Oliinykove. Russian bloggers claimed that Zelene had come under Russian control. Ukraine's 42nd Mechanized Brigade published footage on 10 May of its "Perun" unit destroying four Russian BMP infantry fighting vehicles in the area of Pylna using combat drones, claiming to have inflicted several casualties.

The Russian defence ministry claimed in an 11 May briefing that its forces had taken the villages of Strilecha, Pylna and Borysivka. According to the ISW, geolocated footage published on 11 May indicated that Morokhovets and Oliinykove had also come under Russian control. Furthermore, it was claimed by Russian military bloggers that Russian forces had captured the villages of Hoptivka and on 11 May, though ISW said it had not observed evidence to verify these claims. The Russian Ministry of Defence announced the capture of Krasne, Morokhovets and Oliinykove on 12 May.

Ukrainian outlets Rubryka and Ukrainska Pravda reported that the DeepState map indicated on 13 May that Russian forces had taken control over the village of Zelene, while the village of Lukiantsi was almost wholly occupied. The next day, DeepState reported that Zelene was still under Ukrainian control despite heavy fighting in the area.

A Ukrainian source claimed that Lukiantsi had been captured by 13 May. Russian sources claimed that the entirety of Lukiantsi had been captured on 14 May. The same day, the Ukrainian General Staff reported that Ukrainian forces "repositioned" near Lukiantsi to save the lives of Ukrainian personnel. This was considered a "tacit acknowledgment of Russian advances into the settlement" by the Institute for the Study of War, though it was unable to independently confirm the Russian capture of Lukiantsi until 16 May. Lyptsi village head Serhiy Kryvetchenko announced on 15 May that Russian forces had entered Lukiantsi.

Russian sources claimed on 15 May that Russian forces had captured Hlyboke and Lukiantsi. The Russian Ministry of Defense also claimed that its forces had captured these villages. Russian forces made advances east of Hlyboke and along the east bank of the Travianske Reservoir on 15 May.

The Ukrainian General Staff reported on 15 May that Ukrainian forces repelled Russian assaults between Borysivka and Neskuchne.

Stalemate

Ukrainian Commander-in-Chief Oleksandr Syrskyi reported on 23 May that Russian forces had switched to an "active defense" in the Lyptsi direction, and were no longer performing offensive actions there. Syrskyi also stated that Russian forces were now "bogged down" in street fighting in Vovchansk, which was reflected by Russian milbloggers claims that fighting there had become "positional."

The next day, the Ukrainian general staff said their forces "halted" the Russian advance and "stabilized" the situation along the border. Russian milbloggers reflected this sentiment, calling the front-line "stagnate" and reporting on a failed effort by Russian forces to cross the Vovcha River.

On 29 May, Kostiantyn Mashovets, a Ukrainian military observer, reported that the Russian 18th Motor Rifle Division had switched to an "active defense" while Russian sources claimed that the 25th and 138th motorized rifle brigades, 2nd Motorized Rifle Division, and 47th Tank Division had begun to "conslidate" their positions and engage in defensive efforts.

By 1 June, Russian milbloggers described the offensive as having "stalled" because Russian forces failed to control the battlefield with artillery and air support, attributing Ukraine's defense primarily to the use of drones. The offensive has been described as a Russian strategic failure.
