Trolls are somewhat turning old news into new news.
I did recall Wagner claiming control of most of this mill some weeks ago and there has been fighting around it ever since.
Looking at old contact maps the UAF had control of these city blocks around about 7 March with contact occurring.
Movement of contact points remains fluid and Putin's limited Speznaz VDV and some veteran Wagner fighters are competent. The UAF is attempting to chew these resources up in Bakhmut.
