“… The Russians had 25,000 hard pressed, poorly supplied troops with their backs against the Dnieper with the bridges cut.…”
***************************************************************
Cutting the bridges certainly makes resupply more difficult. But what the Ukrainians (and our resident globalist warmongers) don’t seem to understand is that with the Russians controlling both banks of the river RESUPPLY CAN CONTINUE using ferries and barges… and it is.
You may be right. Thus far no independent reliable source suggesting that this Ukrainian offensive has had any significant success.
Technically it can, but not at anywhere near the same rate as it would if the bridges were intact. The Russians on the west bank will not be able to sustain the same rate of fire without running out of ammunition.
Using boats and barges to ferry supplies across a river is nowhere near as efficient as using railroads or trucks. The Russians may be getting supplies across, but the tonnage moved is significantly less per day. That will hurt Russian combat effectiveness and help the Ukrainians.
