Kherson and Kharkiv are both examples of Russia giving up territory with minimal losses. Kherson was a very famous preemptive withdrawal, with Russia going back on its statements that it would protect the people there. I feel bad for the people there who believed it and tried to build back a functioning society, as they were then subjected to UA's fascistic extremist militants that have wide berth to determine a very low bar for being a "collaborator".

Control maps don't mean much by themselves. A party taking a large strip of mud gets very different media treatment depending on who you read and which party gained it.
