RU POV: Russian and Ukrainian advances from Day 1559 to 1563 of the War - Suriyakmaps

Jun 1, 2026 — Jun 5, 2026 War Day 1559–1563

Please read the dates below before you comment on this post. This one covers the first week of June, not the more notable events that have taken place in the past week and a bit.

I am aware that I am quite behind on the analysis posts but will try to catch up as fast as possible. The next one has 17 images and covers the remainder of early June + some of mid June.

------------------------------------------------------------------------------------------------------

Pictures 1 to 9 are from Day 1559 to 1563 (Monday 01 June to Friday 05 June).

A reminder that these maps are confirming updates from previous days (i.e. typically 24 to 72 hours delayed from each day).

Russian Forces Advance: 8.10 km²

Advance = 8.10km2

Opening on the Sumy border area, from late May and into early June Russia and Ukraine have been shelling each other’s positions in the villages near Hlukhiv, with a smaller advance made by Russian infantry who pushed up the treelines northwest of Sydorivka. The activity in this area remains minimal and whilst we may see some more minor advances in the future this part of the frontline is relatively unimportant for both sides.

No Advance

Onto the main part of the Sumy front, after consolidating in Korchakivka Russian infantry groups are now pushing out into the adjacent forest, attempting to break into the nearby villages of Nova Sich and Ivolzhanske.
Russian Forces Advance: 6.43 km²

Top Top Advance = 1.56km2, Bottom Top Advance = 2.31km2, Lower Middle Advance = 1.94km2, Bottom Advance = 0.62km2

Context
Over on the other side of the Sumy front, in the north Russia continues its attempts to secure Myropillya, capturing some more houses in the town and treelines nearby, whilst clashes are ongoing with the Ukrainian garrison in neighbouring Zapsillya.
Context
Down south, Ukrainian counterattacks in late May have led to their troops managing to break back into Novodmytrivka, recapturing some of the northern streets and treelines where clashes are ongoing.
Context
A similar situation is occurring in Ryasne, with Ukrainian assault groups managing to push back into the western edge of the village and are currently trying to recapture it. I mentioned this likely occurring in the previous post since Russia had not yet consolidated their positions in Ryasne.

No Advance

Moving to the Kharkiv border area, following their capture of Hraniv in late May Russian troops have now begun to move south, testing the waters by heading to the outskirts of Kozacha Lopan. The initial crossings leading to the capture of Veterynarne, Hraniv and Shevchenka did prompt a Ukrainian response (some counterattacks) but it was limited, so this Russian unit has taken the next step to try attack the town with a couple of small groups.

As with all border crossings/incursions there is a balancing act that the defender needs to manage; they cannot simply let the other side run wild and capture locality after locality as it’ll destabilise their defence and could lead to the creation of a proper front, but on the other hand they cannot overcommit their forces as it will weaken other areas where the other side is actually intending to advance. At the moment I highly doubt Russia can capture Kozacha Lopan with the few troops it has deployed here for these border crossings, but Ukraine will eventually need to deal with them.
Russian Forces Advance: 4.74 km²

Advance = 4.74km2

Heading to the Kupyansk front, with Ukrainian defences in the eastern side of the town seemingly collapsing after many months of supply pressure and infiltrations Russian assault groups have begun to push south in larger numbers, taking over a number of streets and some industrial areas, as well as the remainder of Kucherivka (immediately east of Kupyansk). Fighting has now moved into the southernmost streets of eastern Kupyansk and into the northern section of Kupyansk-Vuzlovyi, where Russia is continuing to build its forces (video 1, video 2).
Context
Ukrainian Forces Advance: 24.57 km²

Advance = 24.57km2

Down to the Lyman front, south of the town Ukraine has ramped up its counterattacks/counteroffensive that began several weeks back and has repeated its strategy of flooding infiltrations groups deep into the forests, attempting to reach Yampil once again. Most of this advance is Ukrainian capture of greyzone that was formed several updates back due to the back and forth over this region, however I disagree with some of the newly created greyzone here as like last time these are isolated soldiers or small groups hiding in areas that Russia controls. Like last time Russia will gradually clear them out of Yampil and the surrounding area, before the frontline shifts back to where it was before.

There is also the Ukrainian ‘recapture’ of Pyskunivka (bottom blue dot) and the northern bank of the Siverskyi Donets River that Russia entered in early May, however that also should not have been made greyzone as Ukraine never lost control in the first place (some Russian flags waved by a couple infiltrators who left immediately after).

Russia also stepped up its infiltrations and attacks into Lyman at the same time, which are picking up speed.

Russian Forces Advance: 1.36 km²

Right Advance = 1.36km2

Onto the Kostyantynivka front, in early June the situation continues to quickly deteriorate for Ukraine in the city following the coordinated assault by Russian groups from many sides. Since the previous update Russian forces have been able to quickly overwhelm Ukrainian defenders on the western side of the city, capturing a number of highrises and residential streets (video 1, video 2). A similar situation occurred in the southeast, with other Russian groups capturing the highway interchange and railway station (plus the surrounding buildings).

Whatever defence Ukraine had left in western Kostyantynivka no longer exists, with many soldiers cut off from each other by Russian advances, who are currently trying to flee the across the river to the other side of the city. Some sources have claimed this is a coordinated withdrawal but that is far from the truth, with it actually being a chaotic mess of individual troops trying to get out however they can, with or without approval. Other soldiers have not been so lucky, with a number of isolated Ukrainians being picked off and cleared out by the Russians in several areas (such as video 1, video 2).

On the northern side of Kostyantynivka more Russian groups have been pushing into the city from Novodmytrivka and the nearby treelines, further complicating the situation and wrecking any sort of coherent defence. The battle is far from over but I see little chance Ukraine can recover given their current position, in addition to how difficult it would be to bring in the needed reinforcements from Oleksijevo-Druzhkivka (roads under Russian drone control).

No Advance

Out to the Pokrovske front there has been minimal change in the past couple of weeks. On the east side Ukraine and Russia are clashing next to Berezove and Ternove, whilst west of that Russia was also spotted operating in Danylivka (back in the greyzone).

To the southwest Ukraine has also been hitting the few Russian troops in Ternuvate and Kosivtseve from the north and south, attempting to squeeze them out of the localities.
Russian Forces Advance: 5.88 km²

Upper Right Advance = 4.85km2, Bottom Advance = 1.03km2

Over on the Orikhiv front, on the northeast side Russian forces captured the village of Huliapilske and have been working to expand their control of the nearby farms and treelines now.

To the southwest, Russia managed to push back into Mala Tokmachka slightly, recapturing some houses and the prison. As always, a constant low intensity back and force has been occurring in this town for many months now, neither side able to properly seize control nor willing to deploy the forces necessary to do so.

Ukrainian Forces Advance: 3.35 km²
