Discipline in the ranks of Red Army soldiers in the final period of World War II in Europe left much to be desired. Fighting the Germans, in relation to civilian population and property in the Polish‑German borderlands, the Soviets were guided by a strong desire for revenge on the enemy, which was ineffectively covered up by the new propaganda narrative of “liberation from the fascists”. Until now, this lack of discipline has usually been recalled in the memories of former German residents of the borderlands, noting mainly Soviet plunder and rape of women, and exposing voices on the opposite side that denied them and avoided public condemnation of those considered heroes. This article analyses the military documentation of the Soviet 19th Army, which in March 1945 captured the city and port of Gdynia on the Baltic Sea coast, indicating the mass scale and considerable variety of problems with discipline in the ranks of the victorious army at that time. Based on army orders, the study presents numerous examples of insubordination and violation of military regulations, as well as superficial attempts to prevent and remedy such incidents.
