Russia-Ukraine War: Timeline & Latest Developments

Russia’s full-scale invasion of Ukraine on February 24, 2022 was not the war’s beginning so much as its escalation. Fighting had already run for eight years by then: Russia annexed Crimea in 2014 and backed separatist forces in the eastern Donbas region in a lower-intensity conflict that killed roughly 14,000 people and left front lines frozen along a contact line that shaped where the 2022 invasion’s eastern axis would later push. What changed on February 24 was scale. Russian forces attacked simultaneously from Belarus toward Kyiv, from the Donbas toward Kharkiv, and from Crimea toward Kherson and Mariupol, aiming for a rapid collapse of the Ukrainian government. That plan failed within weeks: Ukrainian forces held Kyiv, pushed the northern advance back by early April, and Russia’s retreat from towns like Bucha exposed evidence of civilian killings that drew international war-crimes investigations, including the International Criminal Court’s 2023 arrest warrant for President Vladimir Putin over the alleged unlawful deportation of Ukrainian children.

The war’s first year set a pattern of dramatic reversal followed by grinding attrition. Russian forces took Mariupol in May 2022 after a brutal siege that Ukrainian officials say killed roughly 25,000 civilians, a figure that has not been independently verified. Four months later, Ukraine’s rapid Kharkiv counteroffensive collapsed a Russian front and, days after that, its southern forces began the campaign that liberated Kherson in November, the only regional capital Russia had captured and then lost. Russia answered by annexing four Ukrainian oblasts it did not fully control and settling into a defensive, attritional strategy built around fortified lines and long artillery duels. That strategy produced the war’s longest and, by most accounts, bloodiest single engagement: the roughly ten-month battle for Bakhmut, a mid-sized Donbas city that Wagner Group forces claimed in May 2023 after reducing much of it to rubble.

Ukraine’s own summer 2023 counteroffensive, built around newly delivered Western armor and meant to sever Russia’s land corridor to Crimea, ran into densely layered minefields and prepared defenses that Russian forces had spent months building. Ukrainian troops captured the village of Robotyne in August, their deepest breach of the war, but never reached the operational objectives of Tokmak or Melitopol, and by December the offensive was widely assessed to have stalled. The following year brought a similar attritional logic in Russia’s favor: Avdiivka fell in February 2024 after months of intense fighting, and Russia opened a new front near Kharkiv that May. Ukraine answered in August with its own surprise incursion into Russia’s Kursk Oblast, briefly holding roughly 1,000 square kilometers of Russian territory before North Korean troops, deployed to help Russia’s defense, contributed to pushing Ukrainian forces back; Russia claimed full recapture of the region in April 2025, though Ukraine disputed the claim. Russia introduced a new weapon into this period as well, firing an experimental Oreshnik intermediate-range missile at Dnipro in November 2024, a strike Putin called a live-fire test of a system he said could exceed Mach 10, a claim that remains a Russian government assertion rather than an independently confirmed capability.

By 2025, the front had settled into a slow, costly grind dominated by drones and glide bombs rather than the mobile offensives of the war’s first two years. Russian forces spent roughly a year encircling and finally entering Pokrovsk, a Donetsk logistics hub, in an offensive US analysts compared unfavorably in pace to the Battle of the Somme; even after taking the city in early 2026, Russian forces made little further progress west of it for months. Diplomacy resumed unevenly alongside the grinding front. A February 2025 White House meeting between President Trump and President Zelenskyy collapsed into a televised shouting match, delaying but not preventing an April 2025 agreement establishing a joint US-Ukraine investment fund tied to Ukraine’s mineral resources. Istanbul talks through mid-2025 produced prisoner exchanges but no ceasefire terms, and Geneva talks in February 2026 made progress on monitoring mechanisms without resolving the core dispute over territory and security guarantees. Competing unilateral truces Russia and Ukraine each declared around May 8-9, 2026 illustrate how far diplomacy still sits from a genuine ceasefire: announced separately, uncoordinated, and not observed as a lasting pause by either side.

The war’s civilian toll has if anything worsened in its fifth year rather than receding. The UN’s human rights monitors recorded Ukraine’s worst monthly civilian casualty figures since the 2022 invasion in April and again in May 2026, driven by long-range missile and drone strikes on cities far from the front line. That intensifying strike campaign culminated in early July 2026, when Russia launched two barrages of roughly 570 and then a second large wave of missiles and drones at Kyiv within days of each other, the second exposing a genuine shortage of Ukrainian air-defense interceptors. The same week, Ukraine opened its defense industry to wartime arms exports, NATO’s Ankara summit pledged roughly 70 billion euros a year in aid, and President Trump pledged to license Ukraine to build Patriot interceptors domestically, though without a signed agreement or timeline attached. As of this writing, Russia holds roughly a fifth of Ukraine’s territory, no ceasefire is in force, and both sides continue absorbing costs, in lives, equipment and economic capacity, that show no sign of a swift resolution.
