Ukrainian Counteroffensive Recaptures Territory in Donbas, Angering Russian Commanders

A secret Ukrainian counteroffensive north of Lyman has recaptured over 100 square kilometers in Donbas, disrupting Russia's plans to fully control the region and angering Russian military bloggers. The operation, dubbed "Vivaldi," was conducted by Ukraine's Third Army Corps over several months. Analysts estimate 100-200 square kilometers were liberated, though Ukrainian official figures are lower. Russia still controls most of Luhansk and about 80 percent of Donetsk. Ukraine's secrecy prevented Russian commanders from sending reinforcements, as false reports up the chain hid the losses. Russian war bloggers now criticize their own officers, warning the setback could delay attacks on Sloviansk and threaten Russian communication lines.
