Chechnya also won its 1st war against Russia, not by decisively defeating it on the battlefield, but merely by outlasting the russians and humiliating them with some guerilla warfare.
The Chechens did win on battlefield, in Grozny in August 1996 when they either killed, captured or surrounded thousands of Russian occupation troops while most of the collaborationist police either defected (Paris 1944 / Prague 1945 style) or deserted. https://reliefweb.int/report/russian-federation/chechens-deadly-swagger
(This most certainly also happened in Warsaw 1944, where the cops were forced back to work by Germans on the pain of death, I just don't remember reading about it specifically other then the Polnische Polizei just never being mentioned by anyone, and all police reinforcements being just the German police from the Warthegau annexed territory, with their strange furred backpacks. While the Russians just shot literally all the police officers they captured in 1939, either immediately or in early in 1940 after interrogations.)
