On the night of 23 September 1943, Dachiev and his friend crossed the Dnieper in the vicinity of Nivki village, in Gomel. On the west bank, he located enemy defenses within a two-kilometer area and managed to successfully deliver the information to the regiment headquarters under heavy enemy fire. Dachiev's actions allowed the entire division to cross the Dnieper on 26 September 1943. For doing so he was declared a Hero of the Soviet Union on 15 January 1944, just a few weeks before the repressions of Chechens and Ingush began. Throughout the remainder of the war he served as a platoon commander after graduating from the Novocherkassk Cavalry School with the rank of junior lieutenant.
