ISW data compiled by the Harvard Belfer Center's Russia Matters project shows Russia lost a net 33 square miles between 17 February and 17 March — the first sustained net Ukrainian territorial gain since the 2023 counteroffensive 1. Russia's advance rate has decelerated fivefold: from 130–150 sq km per week in mid-2025 to 33–50 sq km per week by February 2026. The reversal follows the Zaporizhzhia counteroffensive that reclaimed 460 sq km and eight settlements since late January , which the Institute for the Study of War assessed had 'significantly complicated Russia's plans' for a spring offensive toward Orikhiv.
The cost-exchange ratio compounds the territorial picture. Over twelve months, Russia captured approximately 1,977 square miles — 0.8% of Ukraine's territory — while sustaining an estimated 30,000–32,000 personnel losses per month 2. Mediazona's floor count stood at 203,300 by 13 March ; the Ukrainian General Staff's broader casualty estimate stood at 1,282,570 by 18 March. Syrskyi's January net deficit of 9,000 per month — Russia losing 31,700 against roughly 22,700 recruited — reflects the same structural imbalance.
The Zaporizhzhia sector is where the balance tipped. Syrskyi reported in mid-March that Russia had made it the primary axis of operations, concentrating 'large numbers of troops and resources' around Huliaipole . Zelenskyy stated on 16 March that Ukrainian forces had 'disrupted a Russian strategic offensive operation that the enemy had planned for this March,' crediting the southern counteroffensive . Ukraine's Air Assault Forces alone recaptured 285.6 sq km in February — more than double the roughly 120 sq km Russia seized that month. Russia redeployed elite airborne and naval infantry away from the eastern Donetsk axis to counter the advance .
Ukrainian military analyst Kyrylo Sazonov wrote on Telegram that Russian forces are 'now compelled to allocate resources to defensive stabilisation rather than offensive expansion' 3. That redeployment has not halted pressure around Pokrovsk — which fell in December 2025 — where 18 March saw the highest single-day assault total of the year . But Russia is now fighting on two major axes simultaneously with a force that loses more soldiers each month than it recruits.
