Bath Mode Is Taking a Long Time

Bath mode is taking a long time unlike Sierda Danyansk and Lissniansk how are they holding up well there are still some supply routes and bath mode well. I believe that bath mode will end up similar they will not do the mariupolting they will probably leave through the two country roads all the big roads are now either physically controlled or under fire control. Why won't Russia just drop some fabs some high explosive aerial bombs on bath mode and destroy the whole city with its defenders for good and not do this strike force shenanigans?
