The town itself is not importanrt.
What
@mindlessobserver failed to note is taking the town is necessary, because the AFU was entrenched there. All of the towns on the AFU Donetsk lines are heavily fortified. One cannot take control of the roads that feed into the highway without taking the town; otherwise, they'd have hostiles harassing them from behind.
What ks important is the Road
@Feline Supremacist mentioned in the above post. Because that Road essentially demarcated the principle Ukrainian front line in the Donbass.
It is one of two highways supplying the AFU, the other is the E40 highway
What Feline is not mentionioning however is that the Road she is crowing about does not run through Soledar. It runs on the WEST Bank of the Bakhmutka River. 2 Kilometers BEYOND Soledar at the village of Blahodatne. The only thing on the EAST side of the river is the railroad, and ain't nothing going down those tracks any time soon.
Rail is important and used by both sides, so making sure rail cannot supply the AFU is also an objective.
@mindlessobserver is not familiar with all modes of transport in Eastern Europe, as rail is not as ubiquitous in the US as it is there. The railroads there run north all the way to Moscow and then go through south and then bend around down into Donetsk City.
But to actually cut the road Feline is crowing about, Wagner must charge across 2 Kilometers of open fields, to a river, cross that river, and then assault entrenched positions on the other side. With no air support. In the year of our lord 2023.
Once you realize this, you begin to realize why Soledar only had territorial guards in it.
Wagner and the Russia Federation Armed forces seem to be shelling areas close to the village roads in Novoluhanske and Bakhmut, which lead to the T0513 highway that goes north right into Bakhmut. Securing that route along with the E40 highway would enable the advance on Bakhmut via two converging axis.
Soledar is key to gaining control of Bakhmut, which is key to the liberation of Donetsk. Bakhmut is the foundation of the entire second line of defense of the Keef regime, After that, there's only one last defensive line in Donetsk between Slavyansk and Kramatorsk, further west. Holding Bakhmut threatens further advances and flanks in other directions due to its geographical location.
It would also allow greater control of the Donetsk-Seversky Canal, which provides water to Donetsk City. The Keef regime cut off the water supply to Donetsk five years ago, just like they did to Crimea five years earlier.
So yes, taking and holding Soledar is very important.
