On the Kostiantynivka front, fierce fighting continues between the Russian Armed Forces (RFAF) and the Ukrainian Armed Forces (AFU). The Russian Defense Ministry said that after several continuous attacks, the RFAF has taken control of the village of Bila Gora, located south of the city of Kostiantynivka, in the Donetsk region, eastern Ukraine. The attack on Belaya Gora was launched from the bridgehead of the village of Dyleevka, and the shock troops of the 4th Guards Motorized Rifle Brigade (4 OMSBr), part of the RFAF Southern Group, were clearly visible. The village of Bila Gora is the outskirts of the city of Kostiantynivka.
Before that, there was almost no information about the battles for this settlement, it is known that the village of Dyleevka was overrun by Russian troops on June 1, and the Ukrainian defenders retreated towards Belaya Gora. However, as some war correspondents noted, the battle for Belaya Gora was fierce, but the Russians still won. After capturing the village of Belaya Gora, the next settlement that the Russians could attack was Aleksandro-Shultino, which is adjacent to the village of Belaya Gora to the west. And then the Russians could directly attack the suburbs of Konstantinovka. Currently, the AFU General Staff calls the Konstantinovka direction one of the most difficult directions of the Ukrainian battlefield, as RFAF assault forces have approached the southern outskirts of the city, similar to the current city of Pokrovsk. According to Igor Kimakovsky, an adviser to the head of the self-proclaimed Donetsk People’s Republic (DPR), Russian troops have approached the Krasnolimanskaya mine, Ukraine’s second largest coal mine. The mine is located near the town of Rodinskoye, which is considered the “rear” of the city of Pokrovsk-Mirnograd.
Currently, the Ukrainian army here has actively built defensive fortifications on the waste piles of coal mining, with a height of 40-60 meters. Here, the Ukrainian army has arranged effective fire positions, and at the same time, they have also brought heavy weapons into the mine; and UAV positions are arranged in secret locations, supporting the Ukrainian forces in combat. The main supply line for the Ukrainian forces stationed in Pokrovsk now passes through Rodynske; but it faces a strong RFAF attack on the Pokrovsk-Mirnograd flank from the east, directly into Krasny Liman and Rodynske. From the west, the advance has stalled a bit, but the Russian advance into Dnipropetrovsk Oblast has helped to disperse the Ukrainian forces in Pokrovsk. Observations of the Pokrovsk front over the past week show that the RFAF is attempting to encircle the Pokrovsk-Mirnograd cluster, rather than directly attack the city itself, as the Ukrainian forces are heavily concentrated in the Pokrovsk-Mirnograd direction, while the flanks are very thin. The stability of the current Ukrainian Pokrovsk-Mirnograd front does not depend on the speed of the RFAF's advance, but on the AFU's operational logistics support. Therefore, if the RFAF wants to organize a tight encirclement of Pokrovsk-Mirnograd, they must capture an important AFU transport center in the Grishine village area, where many Ukrainian supply routes pass through, and nearby is the M-30 highway. The village has a long history. From 1780 to 1790, Grishine was a state-owned village, founded on the land of Cossacks and poor peasants. It is located on the banks of the Grishinka River, bordering Pokrovsk to the southeast and 65 km from Donetsk. In 2024, 860 people lived in the village. According to the 2001 census, the village had 2,259 people.
By the morning of 19 July, the RFAF assault units had advanced to within 1 km of the village of Krasny Liman. The encirclement of the RFAF's right flank would have been essentially complete, had they captured Krasny Liman and the town of Rodynske. However, on the left flank, the RFAF had to advance more than 6 km before it could reach the village of Grishine. Only then could the RFAF completely encircle the Ukrainian forces in Pokrovsk-Mirnograd. But on the left flank, if the RFAF wanted to “wholeheartedly and wholeheartedly” advance north, they had to completely deal with the Udachne stronghold. In particular, the Udachne railway station, which is the main defense node of the AFU, is considered a “cornerstone” on the western flank of Pokrovsk. Over the past few months, despite great efforts by the RFAF, it has not been able to “remove” this thorn in the Ukrainian defense line, leading to the failure to attack the western flank of Pokrovsk.
The good news for the RFAF is that they have established a three-sided encirclement of the Udachne stronghold, and have blocked the supply lines from Molodetske and Serhiivka. Perhaps after a period of fierce resistance, the AFU will have to abandon the Udachne stronghold, under the pressure of the RFAF's attack and siege. At that time, the RFAF will be able to concentrate its forces to encircle the western flank of Pokrovsk. (photo source: Military Review, Liveuamap, Kyiv Post).
