The Russian advance in Ukraine has stalled, with the Institute for the Study of War (ISW) reporting a net gain of just 30 square kilometers in June 2026, while Ukraine’s counterattacks have disrupted Russian logistics and inflicted heavy casualties, according to multiple sources.
ISW’s Analysis of Russian Advance Stagnation
The Institute for the Study of War (ISW) highlights a stark decline in Russia’s territorial gains, noting that its net advance in June 2026 was 30 square kilometers, primarily in the northeastern Kharkiv region. This figure contrasts sharply with the 405 square kilometers Russia captured per month in 2025, reflecting a significant slowdown in its offensive capabilities. The ISW attributes this stagnation to Ukraine’s effective use of drones and mid-range missiles, which have targeted Russian supply lines and logistics hubs. “The outcomes from these continuing combat operations remain unclear and will likely be reflected in the data in the coming weeks,” the ISW’s Geospatial Intelligence Team stated, according to Euronews.
The ISW’s analysis also reveals that Russia’s advance in the Donetsk region—where it aims to capture the remaining 20% of territory—has been hampered by Ukraine’s “Logistical Lockdown” strategy. This approach, described by Ukraine’s Defence Minister Mykhailo Fedorov, involves disrupting fuel and ammunition supplies to Russian frontlines. The ISW estimates that Russia’s net gain in the first half of 2026 was just 97 square kilometers, a fraction of the 2,190 square kilometers seized in the first six months of 2025. “If Putin wants to send another million of his soldiers to keep fighting against this wall, then these million Russians, who have not yet been mobilised into the Russian army and are queuing for gasoline, should think about what awaits them next,” Ukrainian President Volodymyr Zelenskyy said, as reported by Al Jazeera.
The ISW’s data also underscores the mounting human cost for Russia. Ukraine’s military estimates that Russia suffered 39,490 casualties in June alone, far exceeding its recruitment capacity of 24,000-30,000 per month. This has led to a casualty rate of 1,298 per square kilometer taken in June, compared to 68 per square kilometer in June 2025. “The extent and scope of the ongoing Ukrainian counterattacks in these oblasts are unclear,” the ISW noted, emphasizing the uncertainty surrounding the war’s trajectory.
ISW reported that Russia’s advance has slowed since late 2025, with Ukrainian forces gaining ground in the Zaporizhzhia and Dnipropetrovsk regions. The ISW’s findings align with Euronews’ analysis, which highlights the frozen frontline and the strategic shift in Ukraine’s approach.
Euronews’ Data on Frontline Freezing
Euronews’ analysis, based on ISW data, confirms that Ukraine’s frontline remained largely frozen in June 2026, extending a trend of stalled Russian momentum. The report notes that Russia’s net gain of 30 square kilometers was largely due to upgrades in previously claimed advances, while Ukrainian forces gained 11 square kilometers in Zaporizhzhia and 18 in Dnipropetrovsk. “The outcomes from these continuing combat operations remain unclear and will likely be reflected in the data in the coming weeks,” the ISW reiterated, as cited by Euronews.
The data also reveals a broader strategic shift. Russia’s average monthly advance in 2026 has been 15 square kilometers, down from 405 in 2025. This decline coincides with Ukraine’s increased use of mid-range strikes, which have targeted Russian logistics, including warehouses, resupply convoys, and bridges. According to Al Jazeera, Ukraine’s Unmanned Systems Forces, led by Robert ‘Magyar’ Brovdi, struck a Russian target every 52 seconds in June. “50,147 military targets were destroyed/damaged,” Brovdi reported on Telegram, as cited by Al Jazeera.
The Euronews report also highlights the human toll, noting that Moscow’s forces have suffered over 2 million military casualties since the war began in 2022, according to a U.S. think tank study. This figure includes both direct combat losses and those from indirect causes, such as disease and equipment failures. “The war, Europe’s deadliest since World War II, has caused more than 2 million military casualties, with Moscow’s forces bearing the brunt of the losses,” the report states.
Euronews emphasized that Russia’s occupation of Ukraine now stands at just over 19%, including Crimea and parts of Donbas. This figure underscores the limited progress Russia has made despite its initial focus on capturing the region.
Zelenskyy’s Strategic Shifts and Casualty Reports
Ukrainian President Volodymyr Zelenskyy has credited his country’s success in 2026 to “a series of decisions” made in 2025, including increased drone production and the development of domestic long-range missiles. These resources have enabled Ukraine to disrupt Russian supply lines, a strategy Fedorov termed “Logistical Lockdown.
