Ukrainian Forces Advance: 3.04 km²

Middle Advance = 2.46km2, Lower Left Advance = 0.08km2, Bottom Left Advance = 0.50km2

Starting today on the Kupyansk front, on the northeast side, Russian assault groups continued to make progress in Petropavlivka, capturing the last of the northern houses and some of the forest area. As mentioned in the last post, Ukraine likely abandoned this area a little while ago due to Russian pressure from the east, falling back to the fortifications in and around Kucherivka. Russian troops are pushing to this area now, where clashes are taking place.

Out west, as I covered in the last post Suriyak has updated the area north of Kupyansk to show a large chunk of the earlier reported gains as greyzone instead, as they have no actually cleared or consolidated here yet.

To the south, Ukrainian assault groups have made a little more progress on the west side of the town, capturing more houses on the northwest and southern sides. Heavy clashes are ongoing, with the Russian forces still in western Kupyansk trying to hold the centre of the town.

Russian Forces Advance: 23.74 km²

Upper Top Left Advance = 0.98km2, Middle Top Left Advance = 0.40km2, Lower Top Left Advance = 0.50km2, Upper Left Advance = 0.34km2, Middle Advance = 15.65km2, Lower Middle Advance = 5.87km2

Russian Forces
Moving onto the Lyman and Siversk fronts, starting with the northwest side, Russian assault groups have made further progress in and around Dibrova, capturing all of the northern houses and some of the adjacent forest areas. They have also cut off the road between Dibrova and Ozerne, meaning Ukrainian troops in the latter are stuck with no land route out (have to cross the Siverskyi Donets or some of the swamps to escape).

Speaking of Ozerne, Russia has also made a small amount of progress in their assault on the village, capturing the first houses on the northeast side.
Context
Over to Siversk, following their capture of the town, Russian assault groups quickly spread out into the surrounding area, capturing a number of fields, treelines and a couple of fortifications to the north and northwest. As I mentioned in the last post, this area was always going to fall to Russia quickly as the Ukrainian survivors from the garrison fled further west, leaving this section empty.

A little to the south, the Russian assault on Sviato-Pokrovske wrapped up shortly after Siversk was captured, with their troops clearing the remaining half of the village and capturing part of the hills to the north. They are now pressuring Riznykivka, where Russia will try to quickly breach the village before Ukraine can reorganise its troops.
Russian Forces

No advance

Down on the Chasiv Yar front, over the past week Russian DRGs have continued their earlier probing north of Virolyubivka and west of Markove, moving through the treelines and gulleys. Ukraine was not covering this area properly, holding positions in the surrounding villages instead, but these DRGs have not consolidated in any of this area yet so it remains in the greyzone.

Russian Forces Advance: 3.97 km²

Advance = 3.97km2

South of Kostyantynivka, some Russian troops have broken west of Ivanopillya, moving up the treelines and one of the gulleys towards the village of Berestok. For the moment they have not pushed any further forward, but if they can assault Berestok it will provide Russia with another angle to enter Kostyantynivka and allow them to link up with other units to the southwest.

For that reason, Ukraine is partially pulling back from the fortifications in the forest north of the Kleban-Byk reservoir, trying to avoid being cut off. The Russian advance here is slow enough that they should be able to withdraw before this happens.
Russian Forces Advance: 6.96 km²

Top Left Advance = 2.50km2, Upper Left Advance = 4.16km2, Middle Left Advance = 0.30km2

Heading to the Hulyaipole front, the Russian assault on the town continues, with their assaults groups capturing a little more of the houses on the northern edge of the locality, as well as some on the southern streets.

A little to the north, Russian assault groups continue to close in on Varvarivka, capturing a number of fields and treelines in the surrounding area. Some troops had already entered the village a few days ago, resulting in clashes.

Russian Forces Advance: 1.93 km²

Advance = 1.93km2

Swinging up to the northern front, the Russian probing mentioned last week into Vovchanski Khutory has borne fruit, with their troops capturing the first houses on the west side of the town. From what I could gather the bulk of the Russian forces in this area are focusing on the battles to the south, with this eastern push being secondary.

Russian Forces Advance: 3.85 km²

Advance = 3.85km2

Following on from picture 1, Russian assault groups quickly crossed the Hnylytsya River in a few new places, capturing a number of farms and some of the forest area north of Kucherivka. As I’ve mentioned before, capturing the village is crucial for Russia here, as it will make it much easier for their troops and supplies to get into eastern Kupyansk and allow them to push further south.
Russian Forces Advance: 6.15 km²

Middle Left Advance = 1.86km2, Middle Right Advance = 1.47km2, Lower Left Advance = 2.82km2

Moving to the Oskil River front, Ukraine recaptured some of the treelines around Bohuslavka (were greyzone), which have been empty since the failed Russian push the other week.

Out east, they also counterattacked and recaptured one of the trench networks next to Nova Kruhlyakivka, slightly improving the situation in the village.

At the same time as these, to the south, Russian forces expanded their control of the fields and one of the fortifications east of Novoplatonivka.
Russian Forces Advance: 2.99 km²

Advance = 2.99km2

Further south on the same front, Russia has made a slight bit of progress in their push towards Korovii Yar, capturing some treelines and part of a few fields.

To the south, clashes are ongoing in the forest, with no clear information on which side is coming out on top.
Russian Forces Advance: 10.43 km²

Advance = 10.43km2

Following on from picture 2, Russia made further advances west of Siversk, quickly clearing a number of fields and treelines abandoned by Ukraine.
Russian Forces Advance: 1.56 km²

Advance = 1.56km2

Onto the southern side of the Siversk front, Russian troops have made another advance west of Vasyukivka, capturing several fields and treelines. They are still avoiding entering the village of Bondarne and look to be trying to skirt around the southern side.
Russian Forces Advance: 3.11 km²

Top Right Advance = 1.87km2, Middle Right Advance = 1.24km2

Over in Myrnohrad, the encirclement continues to tighten, with Russia making more progress in clearing some of the houses on the southern edge of it and a few industrial buildings on the north side.

I have seen claims that organised resistance by Ukraine has ceased, but that has not been confirmed and is a bit pre-emptive.
Russian Forces Advance: 16.87 km²

Top Left Advance = 2.62km2, Upper Left Advance = 2.51km2, Middle Left Advance = 11.74km2

Following on from picture 5, Russian assault groups cleared and captured the village of Varvarivka, as well as the remaining fields in that area. This means Russia now holds control of all settlements east of the Haichur River all the way until it joins with the Yanchur River to the north. This includes the section of Hulyaipole east of the river.

Adjacent to this, at least one Russian group from Dobropillya crossed the Haichur River next to the village, and another crossed the river north next to Nove Zaporizhzhya. This might seem relatively unimportant, but it is notable as it means Russia has breached the 2nd Zaporizhia Defence line for the first time. As I’ve been describing for months, Zaporizhia was defended by 2 enormous fortification lines running from the Dniper River all the way into Donetsk. Both lines have been bypassed by Russian on the Hulyaipole and Pokrovske fronts, but there was still a section standing on the other side of the Haichur River which was crucial for Ukraine to hold. That has now been broken with some trenches in 2 spots being occupied by Russian troops. In their defence, these 2 breaches are small and could be remediated, but if Ukraine does not act quickly Russia may secure a larger foothold and begin pushing into the relatively undefended area further west, which lacks fortifications for tens of km.
Ukrainian Forces Advance: 0.91 km²

Left Advance = 0.34km2, Middle Left Advance = 0.31km2, Bottom Left Advance = 0.26km2

Following on from picture 7, Ukrainian assault groups captured more houses on the north and southern side of western Kupyansk. As I mentioned before, heavy clashes are ongoing all across the town.

Russian Forces Advance: 0.35 km²

Upper Left Advance = 0.28km2, Upper Right Advance = 0.07km2

Following on from picture 3, Russian DRGs have continued making ground around Markove, reaching the village of Fedorivka. Some clashes have taken place on the outskirts of Markove, as Russia secures positions in some nearby treelines in preparation for an assault.

Russian Forces Advance: 4.43 km²

Advance = 4.43km2

Heading over to the Pokrovske front, over the past couple of days Russian troops have secured the village of Ostapivske, which as I explained in the last post was abandoned by Ukraine. Their assault groups did not stop there, moving up one of the treelines to the north and entering the village of Andriivka.

This battle will be somewhat awkward as Russia does not have an easy path to get into the village, but Ukraine mined the bridge on the west side of town before Russia destroyed it with an FPV, meaning their supplies and troops also have an exposed path to get into Andriivka.
Russian Forces Advance: 6.01 km²

Left Advance = 2.30km2, Lower Left Advance = 3.71km2

Following on from picture 5, Russian assault groups in Hulyaipole have made important progress, managing to cross the Haichur River on the north side of the town and secure a foothold in the houses. This limits all movement into Hulyaipole, which were already incredibly difficult (video 1, video 2, video 3) to just the western road.

To the south, other Russian assault groups have capture most of the outer streets with the fighting now primarily taking place in central Hulyaipole. Whilst the battle is certainly not over yet, we are in the final stages as Ukraine is pushed into a small area and their troops are no longer able to withstand the bombardment and assaults.
