This is a special issue of the Rondeli Russian Military Digest dedicated to the Russo-Ukrainian War, composed on the basis of numerous open sources.
Donbas Area - North
Russians likely took village Studenok northwest of Svyatohirsk. Russians’ attacks at Dovhenke and other spots of this part of the frontline did not result in their new advances during the reported period.
Donbas Area - Northeast
Russian forces kept up the efforts to deepen their breakthrough on the Popasna section of the frontline, seeking to surround Ukraine forces defending the Severodonetsk-Lysychansk area.
In the northern part of the breakthrough, Russians took Viktorivka. As of the time of writing, Ukrainians likely retained control of the Vasylivka-Lipove-Vrubivka line in the face of Russian attacks. Attempts by Russians to cut the Bakhmut-Lysychansk highway by advancing from Volodymyrivka to Yakovlivka were repelled. Status of the control over Komyshuvakha was unclear as of the time of writing.
In the southern part of the breakthrough, Russian forces took village Vyskryva.
Heavy fighting continued north, east and southeast of the city of Severodonetsk. Russians attempted to advance directly on Severodonetsk from the north during the reported period, without success. To the southeast of the city, Russians took village Ustinivka.
