Russia took 14 km² in Ukraine in May, its worst month since 2023
Russia captured just 14 km² of Ukraine in May, its lowest monthly total since 2023, and DeepState says the net change went negative as Ukraine clawed back more than Russia took.
Russia captured just 14 km² of Ukraine in May, its lowest monthly total since 2023, and DeepState says the net change went negative as Ukraine clawed back more than Russia took.
Russia captured about 14 square kilometers of Ukraine in May, its lowest monthly total since the period after Ukraine's 2023 counteroffensive, the open-source group DeepState found on June 1, in an assessment carried by the Kyiv Independent and Ukrainska Pravda. DeepState said even 14 km² flatters Russia, because Kyiv withholds some recaptured positions for security.
Counted back in, the month runs negative. Ukraine retook more ground than Russia gained for the first time since 2023, DeepState said. ISW analyst George Barros told The Hill the same, in remarks noted by Euromaidan Press.
The result came despite more fighting. Russian assault actions rose 37.5% in May to more than 7,000, a record, per DeepState and UNITED24 Media. DeepState reads the gap as degraded tactics, with assaults run by small groups and lone infiltrators in place of mechanized columns.
Drones did the stopping, per Euromaidan Press, which credits Ukraine's scaled-up uncrewed air and ground systems, wired through the Delta network that ties sensors to firing platforms, plus strikes on Russian rear positions 100 to 150 kilometers back. Ukrainian ground robots now hold parts of the most contested zones, so an infantry assault meets sensors and munitions before it reaches a trench.
The front has not cooled. The Kyiv Independent wrote that Russian drones killed three people and injured more than 60 in a residential area of Odesa, and Romania's Defense Ministry confirmed a Russian Geran-2 struck an apartment building in Galati on May 29. Kyrylo Budanov, Ukraine's military-intelligence chief, told the Kyiv Independent that Kyiv wants the war over "as soon as possible, preferably before winter."

Frequently Asked Questions
How much territory did Russia capture in Ukraine in May 2026?
About 14 square kilometers, according to the Ukrainian open-source group DeepState, as reported by the Kyiv Independent and Ukrainska Pravda. DeepState called it the lowest monthly figure since the period after Ukraine's 2023 counteroffensive.
What does it mean that the net change went negative?
DeepState reported that once Ukrainian recaptures are counted, Ukraine retook more ground than Russia gained in May, the first time the net monthly figure has been negative since 2023. ISW analyst George Barros told The Hill the same, in remarks reported by Euromaidan Press.
Did Russian attacks decrease?
No. DeepState said Russian assault actions rose 37.5% in May to more than 7,000, a record, a figure echoed by UNITED24 Media. The record attack volume produced almost no territorial gain.
Why did Russia gain so little despite more assaults?
DeepState points to degraded Russian tactics, with assaults run by small groups and infiltrators rather than mechanized columns. Euromaidan Press credits Ukraine's scaled-up drone and ground-robot defense, its Delta sensor network, and strikes on Russian rear positions 100 to 150 kilometers behind the line.
What did Ukraine's intelligence chief say about ending the war?
Kyrylo Budanov, head of Ukraine's military intelligence, told the Kyiv Independent that Kyiv aims to end the war "as soon as possible, preferably before winter."
