The history of the Great Patriotic War has always remained an urgent topic of scientific research. Particularly important is the appeal to military history 75 years after the Victory, when the memory of it requires additional rethinking due to the appearance of previously unknown sources and the consolidation of the results of the battles in the public mind in connection with the death of their participants and witnesses. The liberation of the territory of the Rostov Region in 1943 also belonged to the list of most significant battles of that period. The western regions of the Rostov Region along the Mius River, which received the German name Mius Front, became the most fierce border of bloody battles on the Don. Among the little-studied pages from the history of the battle of Soviet troops on the Mius Front in February 1943, the participation in it of the 33rd Guards Rifle Division, which suffered the most difficult fate of all the rifle formations of the Southern Front during the Rostov offensive operation in 1943, deserves special research attention.
