CHASIV YAR UPDATE
Ongoing battles, including another attempt to cross the canal through the area that is quite dense forest - the canal passes under it.
The Ukrainians saw this coming as the approaches are open territory and repelled the enemy yet again.
Unfortunately the Russians have managed to gain buildings in the eastern part of the canal district of the town.
Because the Russians captured some of the high rise buildings, that reduced Ukrainian fire control over the approaches, allowing more troops and vehicles to use the road to back their forces up.
They used this advantage to bring up more forces quickly, no longer having to cross the open territory and deployed more troops into the contested forest. This is the only way over the heavily defended canal. If they get through this they stand a far superior chance of taking the western part of the canal district and moving to outflank Chasiv Yar from the south.
Once again the problem with the Russians preferred method of troop support - using glide bombs, could no longer be use in the eastern Canal District. Troop positions are too close together and they would simply kill too many of their own forces, so swapping to the south and the forest - and trying to capture the residential housing was an obvious easy option.
They chose the district of Novi.
First they would have to get over the canal and take the forest to create a bridgehead and then, having pushed the Ukrainians out of there, use the open terrain they now had fire control over to push through more forces and swing north into Novi.
That would get the Russians behind the canal, pushing up into Chasiv Yar and collapse the defence of much of the south and east of the city, likely promoting a Ukrainian withdrawal from the canal district before it became untenable.
The problems however were more serious. The plan clearly had merit on paper, but the Ukrainians had laid fortifications, dug trenches and placed mines in the forest, just fighting through it wasn’t going to be easy.
Back in Avdivka one of the most successful moves that undermined Ukrainian southern defences, had been to send troops into the sewers south of the city, bringing them up behind Ukrainian lines - it was remarkably successful and contributed greatly to taking Avdivka. So they planned to do the same again.
Sewer pipes ran under the area Russia had just captured into Ukrainian held areas. So they decided to have another go.
Now you would think they might have assumed the Ukrainians weren’t going to fall for that again, but these are Russians and they don’t often have good ideas. So as they began their advance into the pipes, they were unaware of the drones with thermal cameras watching their every move inside them. The Ukrainians actually published the images.
Drones with grenades backed up by mortar strikes quickly isolated the sections of pipe with Russians in them, creating holes where drone operators then piloted their machines in to take out the Russians still alive.
With the Russians dead in the sewer, a fitting place for them, the Ukrainians mounted a counter attack and took back some of the Russian trenches. The Ukrainians managed to regain control of the forest where it crosses the underground canal.
The entire Russian effort had amounted to nothing, but more dead, more lost vehicles and a position no better than where they started.
An outstanding Ukrainian defence effort playing to Russian weaknesses in planning and their own comprehensive knowledge of the local area.
Slava Ukraini !
