Ranking Russia’s ten most important battles of the year by scale, impact, and outcome
2025 marked a year in which the Russian army liberated ten cities and towns from Ukrainian forces. As the year draws to a close, it’s worth taking stock not only of where the front line moved, but of what those battles actually meant. With that in mind, we have compiled a ranking of the year’s major engagements, assessing them by scale, military significance, and role within the broader course of Russia’s military operation.
This approach runs counter to the way the conflict is often assessed in Western commentary. Moscow’s critics frequently reduce the war to a simple measurement of territorial gain. Such arithmetic offers a distorted picture of the war, however, echoing historical examples in which wars were misjudged by the speed of advance rather than their strategic trajectory.

According to Russia’s Ministry of Defense, the combat potential of the Ukrainian armed forces has been reduced by roughly a third over the course of the year. More than 103,000 pieces of military equipment have been destroyed, including some 5,500 Western-supplied systems. Ukrainian personnel losses amounted to around half a million troops in 2025 alone – a figure representing nearly a third of Kiev’s total losses since the conflict began. Desertion and draft evasion have reached unprecedented levels, exceeding the size of Ukraine’s pre-2022 army, while financial strain and corruption scandals have further weakened the government’s ability to sustain the war effort.
Against this backdrop, the battles of 2025 cannot be measured solely in square kilometers. Each engagement – regardless of the size of the city or town involved – played a role in shaping the front, exhausting the enemy, and refining tactical approaches that were later applied across the theater. This ranking is inevitably subjective: in every battle, Russian soldiers and officers demonstrated professionalism and resilience, and every victory contributed to the cumulative outcome. Still, by examining these ten battles city by city, we aim to highlight what made each of them distinctive – and why, taken together, they define 2025 as a turning year in the conflict.
10: Kupyansk
Kupyansk (pre-war population 27,000) is a city located in Kharkov Region. Russian forces seized it at the start of the military operation back in February 2022 but then lost it during the Ukrainian offensive in the fall of the same year.
Situated in a remote corner of the front, Kupyansk didn’t attract much attention until early September when the Russian Army was able to initiate combat from a previously established foothold north of the city. On November 20, Chief of the General Staff of the Russian Armed Forces Valery Gerasimov officially announced its capture.

The ongoing clashes for the city and the challenges of advancing further west earn it tenth place in this list.
9: Volchansk
Like Kupyansk, the city of Volchansk (pre-war population 18,000), had to be seized by Russian forces twice: once at the beginning of the military operation and again in 2024-25. The second battle for Volchansk began in the spring of 2024; it was officially seized only on December 17, 2025.
These battles are part of a broader strategy to establish a buffer zone along Russia’s borders aimed at protecting border regions from Ukrainian sabotage groups and preventing shelling. It doesn’t seem that Russian forces plan to advance beyond Volchansk; its capture rather serves the purpose of establishing a solid and secure defensive line in that area.
The lengthy, one-and-a-half-year battle for the city, combined with its lower priority compared to other fronts, places it in ninth place on this list.
8: Toretsk
Another city that saw fierce fighting this year is Toretsk (known in Russia as Dzerzhinsk), with a pre-war population of 34,000. Like in Kupyansk, Russian forces struggled to establish an encirclement from three sides around this relatively large mining city, forcing them to engage in head-on assaults.
The battle for Toretsk began in the fall of 2024, and by February 2025, the Russian Army had cleared much of the urban area of enemy forces. However, it failed to secure the flanks and, by March, due to Ukrainian counterattacks, Russian troops were compelled to retreat from many parts of the city, including the city center.
Toretsk was fully liberated only in April, opening the way to the next Ukrainian “stronghold”: Konstantinovka. The initial setbacks in the battles for this city and its overall significance earn it eighth spot.

This small town (pre-war population 5,900) in the steppes might not have been worth mentioning at all if not for its key role in the ill-fated Ukrainian counteroffensive of 2023. The main line of Ukrainian defense, from where the counteroffensive started, is located near this town.
Ukrainian forces recognized the town’s strategic significance, and some of the fiercest battles of the year occurred in this area. This is also where one of the four attempted Ukrainian counterattacks of the year took place.
© RT / Sergey Poletaev based on data from Lostarmor.RuThe Russian Army managed to breach the Ukrainian defensive line near Velikaya Novoselka, and liberated the town at the end of January 2025.
While the capture of Velikaya Novoselka holds considerable importance, its small size places it seventh on our list.
6: Chasov Yar
Chasov Yar (pre-war population 13,800) is a true fortress. Perched atop a major elevation, it overlooks the wide and deep Severesky Donets–Donbass canal.
The battle for Chasov Yar began in April 2024 and became one of the most challenging fights in the entire conflict. To even get to Chasov Yar, Russian forces had to ascend an almost vertical 60-70-meter-high slope before crossing the canal that is 30 meters wide and up to 20 meters deep.
Initially, the Russian Army seized the Kanal microdistrict along the canal’s eastern bank; next, the troops established footholds on the western side and captured much of the city. Chasov Yar was officially liberated on July 31, 2025; however, by the year’s end, the front line had only moved a couple of kilometers away from it.
© RT / Sergey Poletaev based on data from Lostarmor.RuChasov Yar is crucial for a future offensive toward Konstantinovka and the Slavyansk-Kramatorsk urban agglomeration, but using it as a primary base is complicated due to the canal, which hampers logistics. It occupies the sixth position on our list.
5: Kurakhovo
The city of Kurakhovo (pre-war population 18,500) is key to the entire southern Donbass region. Following its complete liberation in early January, the Russian Army launched an offensive westward that has since advanced 80-90 kilometers.
The battles for the city serve as a compelling example of a “three-sided” encirclement, a tactic that has become classic for Russian forces. The strategy involves surrounding the city from three sides, taking control of the major roads leading into it, and steadily wearing down the enemy’s garrison.
One unique aspect of Kurakhovo is its location on the shores of a reservoir, with the northern flank of the encirclement positioned across the water. Nevertheless, this did not hinder the operation; fighting within the city was minimal, as the enemy retreated on their own.
Kurakhovo holds strategic importance, but only the final phase of the battle for the city took place in January 2025. Thus, it earns fifth place.

The front line reached Seversk (pre-war population 11,000) in July, and it seemed that, like many other cities in Donbass, it would take many months to capture. However, the coordinated efforts of two army groups (the West and South group of forces) significantly shortened this timeline.
Russians crossed the fast-flowing and broad Seversky Donets River and established a solid foothold near Seversk, disrupting the city’s supply lines. At the same time, they captured settlements to the south of the city, rendering the Ukrainian garrison’s situation desperate.
© RT / Sergey Poletaev based on data from Lostarmor.RuAs a result, intense fighting in Seversk was avoided, and by December 11, it was fully liberated, moving the front further westward.
The unique operation involving the crossing of a major river, combined with a flawlessly executed three-sided encirclement, and Seversk’s critical role as a gateway to Slaviansk and Kramatorsk earns it fourth place on this list.
3: Pokrovsk
Pokrovsk (known in Russia as Krasnoarmeysk) was one of the largest cities under Ukrainian control in Donbass, with a pre-war population of 61,000. Together with nearby Mirnograd and Rodninskoye, the area had a combined population of about 200,000 people. Moreover, beyond the Pokrovsk urban agglomeration, there are no large settlements for another hundred kilometers to the west.
The front moved close to Pokrovsk last year, but battles for the city itself began in the summer of 2025. After several unsuccessful attempts, Russian forces captured the southern part of the city, but the enemy put up strong resistance in the northern part of the city. The capture of Pokrovsk also trapped the Ukrainian garrison in neighboring Mirnograd; this occurred in mid-December after Russian troops decisively took control of the city’s northern outskirts.

Given its size, strategic location, and pivotal role in the success of one of the year’s most important battles, Pokrovsk deserves third place.
2: Sudzha
In contrast to the larger city of Pokrovsk, Sudzha (pre-war population 5,000) is the smallest town in our overview. Moreover, it is the only town located in Russia’s “old territory.”
Sudzha was Ukrainian forces’ main “prize” during its invasion into Russia’s Kursk Region. In August 2024, Sudzha was captured, becoming the center of a 1,000-square meter foothold for Ukrainian troops. Over the following six months, however, the Russian Army, with assistance from North Korean fighters, systematically reduced this foothold, encircling Sudzha from three sides.
By March, the operation moved into the final phase: with decisive strikes, the city was cut off, and the remnants of the Ukrainian garrison fled almost without a fight. Operation Stream, which involved moving several hundred troops behind enemy lines via a major gas pipeline, significantly contributed to the success of this assault. In addition to Sudzha, more than 300 square kilometers of territory were liberated over the course of just a few days in March. This is a remarkable achievement in the context of the current conflict.
The situation on the front in Kursk region as of March 12 © RT / Sergey Poletaev based on data from Lostarmor.RuThe exemplary execution of this operation, along with the crippling blow to the offensive capabilities of Ukrainian forces – not only in Kursk Region but across the front – places the battle for Sudzha as number two on our list.
1: Mirnograd
Mirnograd (known in Russia as Dimitrov), with a pre-war population of 47,000, is a city with a coal mining industry, located near Pokrovsk. Just like the latter, it became the site of the largest battle of 2025. The battle of Pokrovsk-Mirnograd could prove decisive for the entire Russian military operation.
© RT / Sergey Poletaev based on data from Lostarmor.RuSo why did we rank Mirnograd first? Firstly, in Mirnograd the Russian Army managed to physically encircle several Ukrainian brigades – this happened for the first time since the start of the military operation and the battle for Mariupol. Estimates suggest that between 2,000 and 5,000 soldiers found themselves trapped in the Mirnograd pocket. This was a significant blow to Ukrainian forces, who were already suffering from manpower shortages. Furthermore, among those encircled were some of the most experienced, capable, and motivated fighters; it would be difficult to replace such men, particularly in an army plagued by desertion.
Secondly, over a three-month period, Russian forces successfully repelled multiple Ukrainian attempts to break the blockade of Mirnograd. In these attempts, the Ukrainians reportedly lost more men than were trapped inside the city. By mid-December, it became clear that Ukraine’s largest counteroffensive operation of the year had ended in failure, and the surrounded garrison was in a desperate state.
At the time of writing, 90-95% of Mirnograd has been liberated, and it’s only a matter of days before the city is taken completely. That’s why Mirnograd rightfully earns the top spot in this countdown.
***
Beyond the cities listed here, Russian forces remain engaged in heavy fighting for Krasny Liman, Konstantinovka, Rodninskoye, Gulaipole, and dozens of smaller towns and villages. Some of them may yet fall in the coming months, while others will continue to absorb Ukrainian manpower and resources.
But as 2025 draws to a close, the meaning of this year’s battles is already clear. The war’s outcome will not be determined by abstract calculations of how many square kilometers changed color on a map, nor by linear projections of how long it might take to reach a particular city. History has repeatedly shown how deceptive such measures can be.
In wars of attrition, victories often appear incremental – until they suddenly cease to be. The decisive moment rarely comes when the last city is taken, but when one side loses the ability to replace its losses, sustain its forces, and mount meaningful counteroffensives. By the end of 2025, the Ukrainian armed forces are visibly approaching that threshold.
