Ukraine's Operation Vivaldi reclaims territory near Lyman

newsSep 20, 2026343,211

Ukraine's 3rd Army Corps announced Operation Vivaldi, a counterattack north of the frontline city of Lyman in Donetsk Oblast, corps commander Brig. Gen. Andrii Biletskyi confirmed on Sept. 15. Biletskyi said Ukrainian troops have cleared 75 square kilometers of Russian infiltrators and liberated 10 square kilometers, including the village of Serednie. He described the operation as conducted under conditions of maximum information silence and the 3rd Corps press service declined to comment beyond official statements. Biletskyi said the offensive dealt a heavy blow to the combat capabilities of Russia's 20th and 25th Combined Arms Armies and that Ukrainian drone strikes had pushed Russian supply hubs across the state border. Open sources and Russian pro-war military bloggers reported that Ukrainian forces likely pushed as far as the Zherebets River near the Luhansk Oblast border. Biletskyi earlier challenged Russian claims about capturing Sviatohirsk, saying Russian field commanders had been sending false reports up their chain of command. If Russian commanders lack a clear picture of Ukraine's progress, Kyiv's assessment warns, Moscow may fail to allocate the appropriate resources and make tactical changes, potentially allowing the offensive to continue.

Also, Trump really pulls out the stops to help protect the Russian oil industry--with some laughable lies. phillipspobrien.substack.com/p/weekend-up...
