Soldiers of Poland's Home Army (Armia Krajowa) were persecuted, sometimes imprisoned and, in many cases, executed following staged trials. An example of this was the case of Witold Pilecki, the organizer of Auschwitz resistance.
Units of the Red Army carried out campaigns against Polish partisans and civilians. During the Augustów chase 1945, more than 2000 Poles were captured, and about 600 of them were killed. For more about this subject
There were cases of mass rapes in numerous Polish cities taken by the Red Army . In Kraków, Soviet entry into the city was accompanied by mass rapes of Polish women and girls, as well as the plunder of private property by Soviet soldiers. This behavior reached such a scale that even Polish communists installed by the Soviet Union were preparing a letter of protest to Joseph Stalin himself, while church masses were held in expectation of a Soviet withdrawal.
Latvia
: Soviet occupation of Latvia
In 1939, Latvia fell victim to the Molotov-Ribbentrop Pact between the USSR and Nazi Germany, leading to its annexation and incorporation into the Soviet Union on 5 August 1940. The establishment of a brutal puppet-state, the Latvian SSR, resulted in mass terror, the destruction of civil liberties, the economic system, the Latvian culture. In all, over 200,000 people suffered from Soviet repressions in Latvia, of which some 60% were deported to the Soviet GULAG in Siberia and the Far-East. The Soviet regime forced more than 260,000 Latvians to flee the country.
Lithuania
Lithuania, and the other Baltic States, fell victim to the Molotov-Ribbentrop pact. This agreement was signed between the USSR and Nazi Germany in 1939, leading first to Lithuania being invaded by the Red Army on 15 June 1940, and to its annexation and incorporation into the Soviet Union on 3 August 1940. The Soviet annexation resulted in mass terror, the destruction of civil liberties, the economic system, and Lithuanian culture. Between 1940–41, thousands of Lithuanians were arrested and hundreds of political prisoners were arbitrarily executed. More than 17,000 people were deported to Siberia in June 1941. After the German attack on the Soviet Union, the incipient Soviet political apparatus was either destroyed or retreated eastward. Lithuania was then occupied by Nazi Germany for a little over three years. In 1944, the Soviet occupation of Lithuania resumed following the German army's being expelled. Following World War II and the subsequent suppression of the Lithuanian Forest Brothers, Soviet authorities executed thousands of resistance fighters and civilians accused of aiding them. Some 300,000 Lithuanians were deported or sentenced to prison camps on political grounds. It is estimated that Lithuania lost almost 780,000 citizens as a result of Soviet occupation, of which around 440,000 were war refugees.
During the Lithuanian restoration of independence in 1990, the Soviet army killed 13 demonstrators in Vilnius
Estonia
Estonia was illegally annexed into the Soviet Union on August 6, 1940 and renamed the Estonian Soviet Socialist Republic. In 1941, some 34,000 Estonians were drafted into the Red Army, of which less than 30% survived the war.[citation needed] After it became clear that the German invasion of Estonia would be successful, political prisoners who could not be evacuated were executed by the NKVD, so that they would not be able to make contact with the Nazi government. More than 300,000 citizens of Estonia, almost a third of the population at the time, were affected by deportation, arrests, execution and other acts of repression. As a result of the Soviet takeover, Estonia permanently lost at least 200,000 people or 20% of its population to repressions, exodus, and war.
Soviet political repressions in Estonia were met by an armed resistance by the Forest Brothers, mostly Estonian veterans of the Waffen-SS, Omakaitse militia and volunteers in the Finnish Infantry Regiment 200 who fought a guerrilla war, which was not completely suppressed until the late 1950s. In addition to the expected human and material losses suffered due to fighting, until its end this conflict led to the deportation of tens of thousands of people, along with hundreds of political prisoners, and thousands of civilians lost their lives.
Hungary
During the Siege of Budapest, Hungary, some 40,000 civilians were killed, with an unknown number dying from starvation and diseases. During the siege, an estimated 50,000 women and girls were raped, though estimates vary from 5,000 to 200,000.:129 Hungarian girls were kidnapped and taken to Red Army quarters, where they were imprisoned, repeatedly raped, and sometimes murdered. Even embassy staff from neutral countries were captured and raped, as documented when Soviet soldiers attacked the Swedish legation in Germany.
Yugoslavia
Although the Red Army crossed only a very small part of Yugoslavia in 1944, its activities there caused great concern for the Yugoslav communist partisans, who feared that the rapes and plundering by their Soviet allies would weaken their standing with the population. At least 121 cases of rape were documented later, 111 of which also involved murder. A total of 1,204 cases of looting with assault were documented. Stalin responded to a Yugoslav partisan leader's complaints about the Red Army's conduct by saying, "Can't he understand it if a soldier who has crossed thousands of kilometers through blood and fire and death has fun with a woman or takes some trifle?"
