By mid-August 2025, Russia's full-scale invasion of Ukraine had entered its fourth year, with the most sustained ground fighting concentrated in the east. Russian forces were making incremental advances in parts of Donetsk and Kharkiv regions while Ukraine continued to defend major logistical hubs, conduct counterattacks, and strike military targets deep inside Russia.
The battlefield picture was especially important because U.S. President Donald Trump and Russian President Vladimir Putin were preparing to meet in Alaska on August 15. Ukraine was not represented at that summit, and President Volodymyr Zelensky had repeatedly said that decisions about Ukrainian territory could not legitimately be made without Kyiv.
Russia's pressure in eastern Ukraine
Russia's main ground effort remained concentrated in eastern Ukraine, particularly Donetsk region. Moscow has claimed Donetsk, Luhansk, Zaporizhzhia and Kherson as Russian territory following annexation declarations in 2022 that were rejected by Ukraine and widely condemned internationally. Russia did not fully control any of the four regions at the time.
In August 2025, sources familiar with Kremlin thinking told Reuters that Putin continued to seek full control of those four regions. Kyiv rejected Russian demands that Ukrainian troops withdraw from territory still held by Ukraine.
Trump had publicly discussed the possibility that territorial changes could form part of an eventual settlement. Zelensky rejected proposals requiring Ukraine to surrender additional land and argued that such decisions could not be imposed without Ukrainian participation.
The Dobropillia breakthrough and battle for Pokrovsk
One of the most closely watched developments before the Alaska summit was a sudden Russian penetration near Dobropillia, northwest of Pokrovsk. Reuters reported on August 12 that Russian troops had advanced roughly 10 to 17 kilometers in some areas, apparently exploiting gaps between Ukrainian positions.
The Institute for the Study of War described Russian reconnaissance and infiltration groups operating near Dobropillia and assessed that Russian forces had advanced in several nearby settlements. The penetration did not by itself establish durable Russian control across the entire area, and Ukrainian forces moved to contain it.
Pokrovsk remained strategically important because of its road and rail connections and its role in supporting Ukrainian operations in Donetsk region. Russian forces had spent months pressing toward the city from several directions while Ukraine attempted to prevent its supply routes from being severed.
Zelensky said Russia was seeking to create an impression of rapid progress before Putin's meeting with Trump. That was Kyiv's assessment of Moscow's intentions rather than an independently established motive.
Within days, Ukrainian forces were counterattacking around the Russian penetration. ISW reported on August 15 that Ukrainian officials said the situation east and northeast of Dobropillia had been partly stabilized, illustrating how quickly frontline control could change and why battlefield maps from the period should be treated as time-sensitive estimates.
Chasiv Yar remained disputed
Farther northeast, Russia announced on July 31 that it had captured Chasiv Yar after roughly 16 months of fighting. Ukraine rejected the claim and said combat was continuing.
Reuters verified video showing Russian troops raising flags in the heavily damaged town, but Ukrainian and open-source accounts disputed whether Russia controlled all of it. The distinction mattered because Chasiv Yar sits on elevated ground west of Bakhmut and could support further Russian pressure toward Kostiantynivka and other Ukrainian-held cities in Donetsk region.
Pressure around Kupiansk and northern Kharkiv
Russian forces were also applying pressure around Kupiansk in Kharkiv region. In early August, ISW assessed that Russian troops had advanced toward the western outskirts of the city and were threatening important Ukrainian supply routes.
Farther north, fighting continued near Vovchansk and Lyptsi after Russia opened a cross-border offensive in Kharkiv region in May 2024. Moscow described its operations near the border as an effort to create a security or "buffer" zone, while Ukraine said Russia was attempting to push its artillery and drone operations closer to Kharkiv and stretch Ukrainian defenses.
Kursk, North Korean troops and the northern border
Ukraine had launched its own cross-border operation into Russia's Kursk region in August 2024, temporarily capturing a substantial area. Russian forces later retook most of that territory, with North Korean troops participating alongside Russian forces.
Russia announced in April 2025 that Ukrainian forces had been expelled from Kursk. Ukraine disputed aspects of Moscow's account, while subsequent reporting and battlefield activity showed that operations around the border continued. The presence of North Korean troops in Russia became a significant international dimension of the conflict, with both Moscow and Pyongyang eventually acknowledging their military cooperation.
Ukraine expands long-range attacks inside Russia
Ukraine was simultaneously expanding its ability to strike Russian military infrastructure far from the front. On June 1, 2025, Ukraine's Security Service carried out a large drone operation, known as Operation Spider's Web, against Russian air bases housing long-range bombers.
Ukraine initially claimed that 41 Russian aircraft had been struck and estimated damage at $7 billion. Those figures could not be independently confirmed. U.S. officials later told Reuters that as many as 20 aircraft appeared to have been hit, with around 10 destroyed. Commercial satellite imagery also showed damage to Russian Tu-95 and Tu-22M long-range bombers.
Russia's Defense Ministry acknowledged attacks in Murmansk, Irkutsk, Ivanovo, Ryazan and Amur regions and said aircraft caught fire at bases in Murmansk and Irkutsk while attacks elsewhere were repelled.
Ukraine also continued attacks against Russian oil and military infrastructure, while Russia maintained large-scale missile and drone attacks against Ukrainian cities and infrastructure. Civilian casualty totals from individual strikes frequently changed during rescue operations, making time-specific attribution essential.
Diplomacy and the planned Trump-Putin summit
The Trump administration had been seeking negotiations aimed at ending the war since returning to office in January 2025. By August, however, Russia and Ukraine remained far apart over territory, security guarantees, military restrictions and the sequence of any ceasefire and political settlement.
The White House described the August 15 Alaska meeting with Putin as an opportunity for Trump to assess whether a negotiated settlement was possible. Ukraine and European governments argued that Kyiv had to participate in decisions affecting Ukrainian sovereignty or territory.
Economic relations between Washington and Kyiv had also changed. On April 30, 2025, the United States and Ukraine signed an agreement creating the United States-Ukraine Reconstruction Investment Fund. The arrangement established a framework for joint investment connected to Ukraine's reconstruction and natural-resource development; it was not a defense treaty or a peace settlement.
How the war reached this point
Russia launched its full-scale invasion on February 24, 2022, attacking Ukraine from multiple directions with missiles, aircraft and ground forces. Russian troops initially seized large areas in the north, east and south and reached the outskirts of Kyiv.
The attempt to capture the Ukrainian capital failed. Russia withdrew from northern Ukraine in spring 2022, while Ukrainian counteroffensives later that year recaptured substantial territory in Kharkiv region and the city of Kherson.
From 2023 onward, much of the ground war became a prolonged contest of artillery, drones, infantry assaults, fortifications and logistics, particularly in eastern Ukraine. Russian forces generally possessed greater manpower and ammunition resources, while Ukraine relied heavily on Western military assistance and increasingly sophisticated domestic drone operations.
Military casualty figures remain particularly difficult to verify. Both governments have released selective figures, and outside estimates vary because neither side publishes a complete, independently auditable wartime accounting. Estimates of deaths or total casualties therefore require both a date and a named source rather than being treated as settled totals.
What happened after the Alaska meeting
The August 15, 2025 Trump-Putin summit ultimately produced no ceasefire. After nearly three hours of talks, both leaders said progress had been made but announced no agreement ending the fighting. Trump subsequently met Zelensky and European leaders in Washington as discussions shifted toward possible security guarantees and the terms of a broader settlement.
The diplomatic activity did not end the war. Fighting, long-range strikes and negotiations continued afterward, underscoring the central reality behind the battlefield maps: control along the front can change over days or weeks, while claims by either military require independent corroboration before being treated as established territorial control.
