October 21, 2023 - ISW PressUkrainian forces have likely repelled another intensified Russian offensive effort towards Avdiivka in the past several days and inflicted further heavy personnel and equipment losses on Russian troops in the area. Ukrainian and Russian sources indicated that Russian forces mounted another offensive push on Avdiivka between October 19 and 20, and geolocated footage posted on October 21 confirms that Russian forces did make marginal gains northwest of Avdiivka in the waste heap area. Russian milbloggers claimed that Russian forces are gradually advancing north of Avdiivka near the waste heap towards Berdychi (5km northwest of Avdiivka). A Ukrainian military observer noted that Russian forces are attacking towards Stepove (3km northwest of Avdiivka), towards Novokalynove (7km north of Avdiivka), and towards the waste heap from the Krasnohorivka-Vesele area. However, Ukrainian military officials noted that Russian forces have somewhat decreased the pace of offensive operations near Avdiivka on October 21, and reiterated earlier Ukrainian reporting that Russian forces lost 50 tanks, 100 armored vehicles, and 900 personnel during attacks on Avdiivka on October 19.
