Russian Forces Advance: 5.75 km²

Bottom Advance = 0.98km2, Bottom Right Advance = 4.78km2

Starting this week’s post as always on the Sumy front, Russian troops managed to capture and recapture some treelines south of Varachyne and Yunakivka in mid-May, getting closer to the strip of settlements that run along the Oleshnya River.
Ukrainian Forces Advance: 4.81 km²

Bottom Left Advance = 3.28km2, Lower Left Advance = 0.45km2, Bottom Advance = 1.08km2

Over on the northern front, Ukraine continued their series of counterattacks that began several weeks ago, making progress in a couple of areas. On the west side they managed to move back into central Starytsya, where they had previously been entrenched before being kicked out several months ago.

To the southeast, at least one group of Ukrainian infantry crossed the Siverskyi Donets River and infiltrated Hrafske, where they were targeted by Russian drones. Personally I would mark this as greyzone or an underlayer rather than full control, as getting across this section of the river is difficult and thus Ukraine can’t really secure it without a land connection from the south.

To the east, coordinating with the infiltration mentioned above Ukraine ahs also been launching attacks from the fields east of the forest, aiming to try capture the villages on the flanks and cut-off or force a Russian retreat.
Ukrainian Forces Advance: 20.95 km²

Advance = 20.95km2

Heading to the Kharkiv border area over the past month Ukraine has launched a series of attacks from Kolodyazne, forcing the Russians back from their thinly held positions and recapturing the village of Odradne. Russia has reportedly counterattacked already but no outcome has been confirmed so far.
Russian Forces Advance: 7.10 km²

Top Advance = 5.10km2, Left Middle Advance = 0.89km2, Right Middle Advance = 1.11km2

Down to the Kupyansk front, on the northeast side Russia secured the last street of Petropavlivka, confirming control of the village after months of sporadic fighting. These troops are now moving onto the fortifications southwest of the locality and are trying to dislodge the last Ukrainian defenders who have been stuck there due to DRG activity.

A little to the south other Russian troops have expanded their control of Kurylivka, taking over more of the northern and western buildings (up to Kupyansk-Vuzlovyi), as well as one of the trenches mentioned above.

There have also been Russian attempts to enter Novoosynove to the south, however they have been unsuccessful so far.

No Advance

Onto the Oskil River front, Russia and Ukraine have been going back and forth over the fortifications and treelines around Borivska Andriivka, neither able to properly secure them.

This was also around the time the Russian MOD claimed to control Borova (very bottom of map). As I said in the previous post, whilst Russia has been shown to have some troops in the town these are certainly DRGs and they do not actually control the locality.
Russian Forces Advance: 5.01 km²

Top Right Advance = 1.78km2, Middle Advance = 0.47km2, Lower Middle Advance = 2.58km2, Bottom Advance = 0.19km2

Moving to the Slovyansk front, on the northern side Ukraine has been launching attacks from Rai-Oleksandrivka into northern Nykyforivka, trying to relieve the soldiers that have been trapped in the pocket east of the village. Russia is currently clearing this pocket out now and any remaining Ukrainian troops will have to withdraw before they are overrun.

To the southwest different Russian groups have made small advances along the canal capturing several treelines and fields. There have also been an increasing number of reports of Russian DRGs operating west of the canal around Malynivka and Tykhonivka, so it looks like they will try push the front over the canal rather than settle with it being along it.
Russian Forces Advance: 3.85 km²

Middle Right Advance = 1.84km2, Right Advance = 0.96km2, Bottom Advance = 1.06km2

Down to the Kostyantynivka front, Russia has launched new attacks and infiltrations in and around the city over the past week. On the east side they increased their control of the outer houses and fields, with some troops moving up into Novodymtrivka and even Molocharka where they are trying to consolidate.

To the southwest, the Russian assault groups that entered the city the previous week have expanded their control and are trying to take over the industrial area on south side of the Kryvyi Torets River. If they can capture it and the surrounding buildings then the city will be split in two, with an isolated pocket of Ukrainian control further south.
Russian Forces Advance: 21.40 km²

Top Right Advance = 3.47km2, Upper Middle Advance = 4.89km2, Middle Advance = 2.35km2, Bottom Advance = 10.70km2

Over on the Hulyaipole front, on the north side Russia forces resecured the fortifications west of Dobropillya, putting them back in control of most of both sides of the Haichur River.

A little southwest of this the Russian assault on Vozdvyzhivka is ongoing, with Russia securing the eastern houses and moving further into the town. I had read claims they had secured the entire locality already but that has not been proven yet.

To the south, other Russian groups recaptured Tsvitkove and continued with their assault on Verkhnya Tersa (above the a).

To the southwest, after forcing Ukraine out the previous week Russia captured the village of Charivne and many of the fields east of it. This puts Hulyaipilske (immediately north of Charivne) in a bad position as its supply routes are limited and the Russians can assault it from three separate sides.
Ukrainian Forces Advance: 0.76 km²

Advance = 0.76km2

Out on the Zaporizhia front Ukraine is continuing its counterattacks that began some time ago, dropping more troops in northern Stepnohirsk and recapturing most of it. Interestingly this is the third Ukrainian mechanised attack to drop troops into that same area, with the previous ones also having similar videos released but not making any progress (they occurred some months ago).
Ukrainian Forces Advance: 11.22 km²

Bottom Left Advance = 0.80km2, Lower Left Advance = 10.42km2

Following on from picture 2, on the northeast side Russian troops captured the village of Rybalchyne along the international border. As with all these border settlements they are typically empty and held by drones and rarely by soldiers, so this was a simple matter of walking in and checking the few houses for any troops.

To the southwest, over a week of clashes Russian forces managed to capture most of the village of Volokhivka, which sits on the other side of the Vovcha River. The Russians claim full control of it and Karaichne, with some video evidence, but Suriyak is being conservative here and is likely waiting for further evidence of Russian control.

To the southwest Ukraine continued their attacks and began to push into Lyman and Synelnykove, following their reported recapture of Vilcha. I do think Suriyak has jumped the gun slightly here as the only evidence of the Ukrainians in Lyman and Synelnykove were short clips of a couple of soldiers being droned, so it would be more accurate to mark this greyzone or an underlayer of Ukrainian control rather than full control.

Out west Ukraine also captured a couple more houses in Starytsya, although are running into stiffer Russian resistance.
Context

No Advance

Down to the Lyman front, on the northwest side some Russian troops crossed the Siverskyi Donets River and entrenched themselves in Pryshyb on the opposite side, followed by intense shelling of the surrounding area. This isn’t the first Russian crossing here but it does somewhat baffle me as they do not have good control over this frontline and there are many other areas that would be better to attack first rather than trying to set up a bridgehead over this river.

To the east Ukraine is making yet another attempt to recapture Stavky, pushing into the outer warehouses from the west.
Russian Forces Advance: 7.92 km²

Middle Left Advance = 1.71km2, Bottom Advance = 6.21km2

Following on from picture 6, Russia made a small advance west of Kalenyky as they attempt to reach the forest north of Rai-Oleksandrivka.

To the south other troops also captured more of the pocket next to Nykyforivka, now only a fraction of the size it was several weeks ago.
Russian Forces Advance: 0.21 km²

Advance = 0.21km2

Heading to the Dobropillya front, Russia resecured Toretske after the previous Ukrainian attempt to recapture it and has been sending DRGs out into the fields east of Kucheriv Yar.

No Advance

Following on from picture 8, Russia has stepped up its assaults and DRG movements across this frontline, further pushing into Vozdvyzhivka (top) and Verkhnya Tersa (middle), trying to reach the cluster of settlements around Dolynka.

They have also flanked Hulyaipilske to the south, with Russian infantry moving into the warehouses and trenches immediately north of the locality. This part of the Ukrainian defence line being occupied would doom Huliapilske, as their supplies would be completely cut off and the only viable evacuation route would be to try assault over the fortifications (trenches, ditches, dragons teeth, etc) they just lost.
Ukrainian Forces Advance: 11.30 km²

Middle Advance = 1.13km2, Lower Left Advance = 10.19km2

Onto the Orikhiv front, with Mala Tokmachka seeing virtually no fighting in the past three months there has not been an update until now. Russia still maintain control of the eastern edge of the town, however Ukraine recaptured some of the houses in the central section at some point this year and has started to move back into the fields and treelines south of the locality (has been greyzone for months).

To the west, Russia abandoned its assault on Novodanylivka, although as I mentioned quite a while ago now this occurred shortly after the assault began, so this is a months delayed update.
Ukrainian Forces Advance: 20.29 km²

Left Advance = 7.40km2, Right Advance = 12.89km2

Following on from picture 9, on the west side Ukraine continued their attacks and has pressed down through southern Prymorske, recapturing most of the remainder of the town. They will be attempting to drive the Russians back over the stream here so they can reestablish their defences along it, same as they held late last year.

To the east other Ukrainian units have cleared the former Russian salient that they were forced to withdraw from a few weeks ago and is now pushing through the fields. They too will continue to attack and try force their way into the lightly defended Russian lines south of the fortifications.
Russian Forces Advance: 4.59 km²

Top Right Advance = 2.77km2, Upper Right Advance = 1.82km2
