No. Russians got into some of the lower-lying areas to the north. The Ukrainians blew a small dam to flood some of those areas yesterday. You need to see the positions overlaid on a topographic map. Other sources I've seen estimate the number of Ukrainian troops in Bakhmut at 4500. The Ukrainians actually pushed back some of the Russian forces to the south last week.
The notion that the Ukrainians haven't built a second line of entrenchments or even a third line is incredible as that is what they always do.
In any case temperatures have now risen to the lower 40s and it's raining, meaning mud season is upon both sides. So there is unlikely to be any major movement until April.
Good point, saw the map of the secondary trenches to the nw and sw
