To the south, in an unexpected turn of events, Russian forces bypassed the Ukrainian trench network west of Mykolaivka, which I mentioned yesterday (No. 1 on pic), and managed to advance south along the treelines and capture a different trench network (No. 2 on pic), rapidly overwhelming the Ukrainian defenders. This advance means Russia has effectively severed the E50 highway between Pokrovsk and Karlivka, although there is another long route through Seledove. Ironically this also puts them into a position to capture the mine next to the slag heap outside Selydove, which another user asked me about in the last update. Russian command may be considering an attack on Selydove first, before they head for Pokrovsk, which I detailed in this comment.
Just to the east of here, Russian forces advanced south from Zhelanne, capturing Novozhelanne, and clashing with Ukrainian rearguard units. Ukrainian forces in this area, likely the 68th Jager, 25th Airborne, and 117th Mech brigades are currently in mass retreat, as their supply lines have been cut and the frontline partially collapsed. These units will likely not get encircled, however they are still taking casualties and losing equipment trying to stall Russian forces.
