First bridgeheads established and capture of Dvorichna (November 2024 — January 2025)
On 26 November, Russian sources claimed that Russian forces had used boats to cross the Oskil River and had entered the town of Dvorichna. [8] The next day, Russian sources claimed that Russian forces were also attempting to cross the Oskil near the village of Novomlynsk, [9] and that fighting was ongoing on the outskirts of Dvorichna. [10] The following day, Ukrainian officials acknowledged that a small group of Russian forces had crossed to the west bank of the Oskil. [11] [12] [13] According to Ukrainian military observer Kostiantyn Mashovets, Russian forces had crossed the river near a suspension bridge south of Novomlynsk [ uk ], and the Russian contigent on the west bank of the Oskil was no larger than a company-sized force. [14]
By 1 December, Russian forces had also crossed the Oskil River south of Dvorichna, establishing a second company-sized bridgehead in the area of Masiutivka and Zapadne, according to Mashovets and Russian sources. [15] Russian sources claimed that Russian forces advanced into a forested area west of the village of Masiutivka. [16]
On 3 December, it was reported that the 8th Battalion of Ukraine's 10th Mountain Assault Brigade and the 2nd Battalion of the 3rd Tank Brigade had cleared Russian forces from Novomlynsk and the surrounding area. [17] [18] Geolocated footage indicated that Ukrainian forces were in control of the village. [19] The Ukrainian military claimed that the Russians were forced into a chaotic retreat across the river. [17] Mashovets said the next day that the Russian bridgehead at Novomlynsk had been eliminated and that the bridgehead at Masiutivka-Zapadne had been "significantly reduced" by Ukrainian forces. [20]
However, in mid-December, Mashovets said that the latter Russian bridgehead had "significantly expanded" [21] and that Ukrainian forces had seemingly retreated to the Dvorichna-Kupiansk highway. [22] By late December, Russian sources claimed that Russian forces had advanced to the highway [23] and in early January, Mashovets said that Russian forces were using the highway to advance towards Zapadne. [24] The Russian military claimed to have taken control of Zapadne on 22 January. [25] [26] Footage of Russian forces in the center of the village was published on 4 February. Mashovets acknowledged the next day that Russian forces had seized the village. [27] [28]
Russian forces advanced in the southern and southeastern parts of the town of Dvorichna in mid-December. [29] [30] By mid-January, Mashovets claimed that half of the town was held by Russia's 69th Motor Rifle Division. [31] The Russian military claimed to have taken control of Dvorichna on 28 January, crediting the 25th Motor Rifle Brigade with its capture, [32] but a local Ukrainian official disputed the claim. [33] [34] [35]
In early January, Russian sources claimed that Russian forces had reached the village of Kalynove [ uk ] from the northeast, [36] and the Russian military claimed to have seized Kalynove on 12 January. [37] [38]

In mid-January, Russian forces crossed the Russia-Ukraine border and advanced near the border village of Topoli. [39] [40] In early February, Ukrainian and Russian sources reported that Russian forces had established a bridgehead over the Oskil near Topoli, taking up positions on Mount Milova, south of the village. [41] [42] [43] In mid-February, Russian forces advanced near the village, entering its center. [44] [45] On 24 February, the Russian military claimed to have taken Topoli. [46]

By early April, Russian forces had advanced across the Oskil River into the southeastern part of the village of Kamianka, [58] and continued to advance in and around the village throughout the month. [59] [60] [61] [62] On 28 April, the Russian military claimed that the 69th Motor Rifle Division's 344th Motor Rifle Regiment had taken full control of Kamianka, [63] although a Ukrainian military spokesman claimed that there were still Ukrainian positions in the village. [64]
South of Dvorichna
In February, a Russian source said that Russian forces were planning to conduct an offensive south of Zapadne. [65] Mashovets claimed that elements of the 69th Motor Rifle Division were advancing southwards towards Kindrashivka [ uk ] along the Oskil River. [66] [67] By early March, Russian sources claimed that Russian forces had advanced and reached Kindrashivka, reportedly as part of an effort to interdict the Velykyi Burluk-Kupiansk road and enable future attacks on Kupiansk from the northwest. [68] [69] In early April, Russian sources claimed that Russian forces had entered Kindrashivka and established positions in the northern part of the village.

Russian forces enter Kupiansk (July – November)
In late July, a Ukrainian military commander warned that Russian forces were attempting to infiltrate into Kupiansk via Holubivka and Kindrashivka. [104] Russian forces, reportedly of the 121st Motor Rifle Regiment, [105] took control over Holubivka by 24 July, [106] and Russian forces advanced into northern Kupiansk the same day. [107] [108] Later in July, a Ukrainian officer claimed that Russian forces were attempting to flank Kupiansk from the west. [109] By early August, Russian forces had advanced northwest and north of Kupiansk as part of an effort to envelop and seize the city, [110] [111] and had secured positions in the western outskirts of the city. [112]
Throughout August, Russian sources claimed that small groups of Russian forces were infiltrating Kupiansk and were holding positions in buildings on the city's outskirts. [113] [114] [115] By 24 August, Russian forces had advanced within the northern part of Kupiansk. [116]
On 30 August, the Institute for the Study of War assessed that Ukrainian forces had retaken Myrove and Sobolivka. [117] Russian forces retook Myrove by 2 September, [118] though Ukrainian forces recaptured Myrove again by 24 October. [119]
In late August, a Ukrainian military commander claimed that Russian forces were attempting to infiltrate into Kupiansk through sewer lines. [120] In early-mid September, Russian forces attempted to infiltrate northern Kupiansk through an underground gas pipeline [121] between the villages of Lyman Pershyi and Radkivka, [122] according to statements by Ukrainian military officials. [123] [124] Ukrainian forces reportedly later damaged the pipeline to prevent further infiltration attempts. [125] [126] [127]
By 6 September, Russian forces had advanced into the northwestern part of Kupiansk and established forward positions. [128] By 14 September, Russian forces had advanced in central Kupiansk, [129] reaching Sadova Street two days later. [130] Mashovets said that Russian infiltration and assault groups had been detected near the Spartak Stadium and Dovhalivska Street. [131] On 20 September, Russian sources claimed that Russian forces had seized the Kupiansk-Pivdennyi [ uk ] railway station [132] and advanced into the Yuvileinyi district in southwestern Kupiansk, interdicting the Kupiansk-Kharkiv highway. [133] According to Ukrainian military journalist Yurii Butusov [ uk ], in mid-September, Russian forces captured an important height north of Kupiansk, which placed the Ukrainians in a "critical" situation. [134]
In the beginning of October, Russian sources claimed that about one-third of the city was under Russian control, [135] while a Ukrainian military commander said that Russian forces only held positions in the city's northern outskirts. [136] Russian advances continued in central Kupiansk in early October. [137] [138]
On September 18, the BBC reported that a new push into Kupiansk is led by former Ukrainian officer Serhii Storozhenko who is currently leading the 6th Combined Arms Army, the next day, Russian forces attempted to infiltrate the city using underground pipes. [139]
On 28 September, the head of the Kupiansk City Military Administration, Andrii Besedin, announced the city's closure to civilians. [140]

[144] [145] [146] [147] By 9 November, Russian forces had infiltrated southwestern Kupiansk and occupied a building on the H-26 Kupiansk-Kharkiv highway. [148]
Russian declaration of "full liberation" and Ukrainian counterattack (November-December)
On 20 November 2025, Russian general Valery Gerasimov publicly announced that Kupiansk had been fully captured by Russian forces [149] [150] of Army Group Zapad. [151] The Russian ministry of defense credited the 27th Motor Rifle Brigade and 1486th Motor Rifle Regiment with capturing Kupiansk. [152] General Sergey Kuzovlev reiterated the news in the presence of Putin, wearing a quasi-military uniform, who clarified "so that's it, completed it all?" to Kuzovlev's confirmation. [151] The next day, Putin said that Russian forces would "inevitably repeat" what had occurred in Kupiansk on other areas of the front. [153]
The supposed capture of Kupiansk was disputed both by Russian sources [154] [155] and the Ukrainian military, [156] which claimed that the groups of Russian soldiers in Kupiansk numbered about 40 total personnel. [157]
On 27 November while speaking to journalists, Putin once again referred to Kupiansk, saying that "as we know the enemy formations are fully liquidated there", [151] and also said on 2 December that all of Kupiansk had been under complete Russian control for several weeks. [158]
However, during the following weeks Ukrainian forces conducted a series of counterattacks, which resulted in the elimination of the Russian assault forces from the town centre. The operation culminated with President Zelensky visiting the entrance to the city in person on 12 December and recording a video at the distinctive monument with the town's name. [159]
The 2nd Corps of the National Guard of Ukraine reported on 12 December that as a result of a Ukrainian counterattack, the villages of Kindrashivka and Radkivka had returned to Ukrainian control, as well as areas in northern Kupiansk. [160] The 2nd Corps claimed that Ukrainian forces broke through to the Oskil River as part of the counterattack, cutting off Russian lines of communication to Kupiansk [161] and surrounding 200 Russian personnel in the city. [162] According to a Ukrainian military report, these advances were the result of a multi-week effort beginning on 16 November. [163] However, Butusov claimed that Ukrainian forces had recaptured Kindrashivka by 9 October, Radkivka by 11 October, and reached the Oskil River, cutting off Russian lines to Kupiansk, by 21 October. [164]
On 13 December, Butusov said that Ukrainian forces had retaken full control over Kupiansk's Yuvileinyi District. [165]
