Russia is relocating troops from the still active defense of Bachmut to the front around Zaporzhizhia, where their positions are being pummelled by the Ukrainian counter-offensive. This means that Russia has no reserves to fortify at points of attack and replenish their losses. Every soldier they have in active duty is already deployed along the front in the occupied part of Ukraine.
Along with Putin's recent desperate outreach to North Korea, which tells us he is running out of ammunition and has no friends left who can help him in a meaningful way, we are likely watching the last gasp from Russia in the conflict they started. That last gasp might last for a good while and cost far too many more lives, but we are at least getting closer to the end.
