If the Kinburn / left bank rumors are true (which they seem to be) then it seems pretty genius. The justification for the withdrawal from the right bank by the Russians was to consolidate their defense of Zaporizhzhia and Donetsk / Luhansk. The avenues of attack would be fairly predictable; either straight south towards Melitopol and east towards Donetsk city. Either way, the Russians could effectively fight a single-front war, throw conscripted bodies into the meat grinder, and push for a “diplomatic solution” that would allow them to keep the territory they currently hold.
What they didn’t plan on was that all of those forces that were just transferred across the river would be immediately attacked from the west.
Now they have a dilemma. Do you leave the forces in place and try to defend Crimea and get forced to use the extremely long road from Mariupol to supply them? Because of the symbolic and strategic importance of Crimea to Russia, this seems like the most likely path. But now all of those eastern forces will not get the expected reinforcements and the supply lines are just as stretched as they used to be.
The other option would be to fall back to Donetsk and give up Crimea plus all of the captured Black Sea / Azov coastline. This would be political and possibly, literal suicide for Putin.
It’s a beautiful thing to see.
