Ukraine is advancing from its bridgehead across the Dnipro River which is proving to be a growing problem for Russia.

It keeps popping up in increasingly higher profile and better sourced reports. Too early to call this a full blown "Thing".
Obvious problems in sustaining across this river. Heading into the mud season, to be followed by winter. And of course about a hundred other things.
But one thing is a solid fact now. The Ukrainians have turned this operation into a bigger problem than would ever have seemed possible.
