RU POV: Russian and Ukrainian advances from Day 1420 to 1421 of the War - Suriyakmaps

Jan 13, 2026 — Jan 14, 2026 War Day 1420–1421

Because of the combined days I don’t have space to include Day 1422 and 1423. So those will be in the next post.

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

Pictures 1 to 14 are from Day 1420 to 1421 (Tuesday 13 to Wednesday 14 January).

A reminder that these maps are confirming updates from previous days (i.e. typically 12 to 72 hours delayed from each day).

Live map can be found here, Suriyak’s twitter can be found here.

Russian Forces Advance: 2.51 km²

Advance = 2.51km2

Beginning on the Sumy border area, following their small crossings a little over a week ago, Russian troops managed to capture the village of Komarivka. Like with the other crossings in Sumy Oblast, Russia is trying to pull units on this front away to these remote villages, in order to create openings on the main part of the frontline where Russia might be able to push through.
Russian Forces Advance: 2.22 km²

Lower Left Advance = 1.63km2, Bottom Advance = 0.59km2

Onto the northern front, Russia made further advances in the forest south of Vovchansk, capturing more of the area south of Prylipka (below the r), as well as a small section east of Hrafske.

No Advance

Over on the Kupyansk front, Russia further expanded their DRG activity northwest of the town, sending their DRGs across the fields past Radkivka, moving into Moskovka. Ukraine was unable to consolidate in this area following their counterattacks last year, allowing Russia to exploit the lack of troops and try move back into the positions they lost.

In central Kupyansk there was also an expansion of the greyzone as Russian troops persist in holding the central buildings, occasionally pushing out trying to recapture buildings to the west.
Russian Forces Advance: 3.35 km²

Advance = 3.35km2

Down on the Oskil River front, Russia managed to recapture two of the trench networks east of Nova Kruhlyakivka, bringing the frontline back to the outskirts of the village once again.
Ukrainian Forces Advance: 3.08 km²

Top Advance = 2.07km2, Bottom Advance = 1.01km2

Further south on the same front, both Russia and Ukraine made minor advances in Luhansk Oblast in the past couple of weeks, with Russia creeping forward slightly to the eastern edge of Tverdokhlibove, whilst Ukraine recaptured a couple of treelines next to Hrekivka. Not much to add here, as its just minor opportunistic movements by the few troops present in this area for both sides.
Russian Forces Advance: 3.15 km²

Left Advance = 1.39km2, Lower Left Advance = 0.62km2, Middle Left Advance = 1.14km2

Heading to the Lyman front, on the west side, Ukraine counterattacked against the Russian DRGs on the outskirts of Sosnove and Svyatohirsk over the past week, managing to drive them out and resecured the outskirts of the villages.

At the same time to the east, Russia expanded its control of Yarova, with most of the village moving into the greyzone as Russian DRGs are scattered all throughout it, but it’s unclear where the Ukrainian defenders are.

Russian Forces Advance: 2.06 km²

Advance = 2.06km2

On the Siversk front, Russian troops made a minor advance southeast of Zakitne, whilst clashes continued within the village.
Russian Forces Advance: 13.83 km²

Upper Right Advance = 3.23km2, Middle Advance = 10.60km2

Further southwest on the same front, Russia made several larger advances over the past week in two areas. On the north side, they moved north of the Babachyi Forest, entering the Sorochyi forest and captured part of the adjacent hill.

To the southwest, Russian assault groups managed to capture the remainder of Bondarne, securing full control over the village. They quickly moved into the treelines and fields north and northwest of the village, managing to clear a large area and enter the first houses of Nykyforivka (under the y). The front is moving dangerously close to Rai-Oleksandrivka, which is one of the last Ukrainian strongholds east of the canal.

Russian Forces Advance: 8.99 km²

Middle Advance = 2.02km2, Bottom Advance = 6.97km2

Southwest of Kostyantynivka city, Russian forces cleared out that small pocket that formed due to their advances a couple of days prior, taking over the treelines and a few dugouts. Judging by the lack of footage and reports, the Ukrainians likely weren’t present here when this area was cut off or broke out a few days prior.

North of this, the Russian push through the ravine leading to Illinivka has turned into full control of the area, with Russian assault groups clashing with Ukrainian troops within the village as they try to establish control over it. At least one DRG even managed to push north of Illinivka, moving into the outskirts of western Kostyantynivka. If Ukraine cannot stabilise here, they will quickly find themselves in a lot of trouble as the Russians will be able to push into western Kostyantynivka and squeeze the units inside against the Russian position on the east side of the city.
Russian Forces Advance: 4.23 km²

Top Advance = 2.07km2, Upper Left Advance = 2.16km2

Moving to the Dobropillya front, on the north side, Russian troops have pushed north of Sofiivka, capturing several treelines and reaching the village of Novopavlivka. This is the first village in a chain the links to Druzhkivka, so Russia will need to capture it to lay the groundwork for their push on the city.

Out southwest, other Russian troops captured one of the quarries next to Chernyavskiy, opening the way for a push north on Kucheriv Yar.
Russian Forces Advance: 2.60 km²

Upper Middle Advance = 1.94km2, Middle Left Advance = 0.66km2

North of Pokrovsk, Russia continues its attempts to expand the buffer around the city and force the Ukrainians away, capturing several treelines along the road to Hryshyne and west of Rodynske.

Speaking of, Ukraine continues to launch assaults on the town, trying to expand their foothold yet again. In return Russia has been hammering the mine out west of Rodynske, through which Ukrainian troops head into the town.
Russian Forces Advance: 5.70 km²

Advance = 5.70km2

On the Novopavlivka front, Russia made further advances east of the town, capturing more treelines as they force Ukraine back into the locality.
Russian Forces Advance: 5.45 km²

Top Advance = 1.75km2, Upper Middle Advance = 1.87km2, Bottom Advance = 1.83km2

Heading over to the Hulyaipole front, Russia continues to breach the Ukrainian fortification line, expanding their control of the area outside Pryluky, as well as moving into the village of Oleknokostiantynivka which sits at the curve of the line.

Further south, Russia cleared the last treeline along the road out of Hulyaipole, straightening the the frontline in this area. This group will continue to slowly work their way west until they reach the railway that runs south of Zaliznychne.
Russian Forces Advance: 19.78 km²

Upper Left Advance = 12.29km2, Middle Right Advance = 7.49km2

Out west on the Zaporizhia front, Russian assault groups made a series of significant advances over the past few days. On the west side, with Prymorske mostly under their control some Russian groups fanned out into fields east of the town, capturing a large area of fields and treelines (undefended). Other groups have already been report to have moved further out into the area I mentioned in the last post.

North of this, at least one Russian DRG pushed through the northern dachas of Prymorske and managed to reach the dachas southeast of Richne (just off map north) and the bridge over the Konka River. This led to Ukraine blowing the bridge up to prevent the Russians from crossings over into Hryhorivka, which is ironic given that it was Russia who tried to destroy this same bridge a few months back.

To the southeast, Russian assault groups fanned out into the area east of Lukyanivske, capturing a number of treelines and fortifications, as well as entering the nearby settlements. Ukrainian lines here are so weak that the Russians are actually assaulting 3 villages simultaneously (Novoboikivske, Novoyakovlivka and Pavlivka), whilst other troops are still mopping up the village behind them (Lukyanivske). There were even reports from the Ukrainians that a Russian DRG managed to sneak into Mahdalynivka and ambush a drone team, reinforcing how sparse their lines are here.
