SorokLag: Russian concentration camp and forced labour camp (part of Gulag penal system), near Bielomor canal. The prisoners slaved at, among others, railroad and road construction (Plesetskoje–Onega on the White Sea). (more on: www.gulagmuseum.org [access: 2014.09.21])

Gulag: Network of Russian slave labour concentration camps. At any given time up to 12 mln inmates where held in them, milions perished. (more on: pl.wikipedia.org [access: 2014.05.09], en.wikipedia.org [access: 2014.05.09])

Minsk: Russian prison. In 1937 site of mass murders perpetrated by the Russians during a „Great Purge”. After Russian invasion of Poland in 09.1939 and start of the II World War place of incarceration of many Poles, In 06.1941, under attack by Germans, Russians murdered there a group of Polish prisoner kept in Central and co‑called American prisons in Mińsk. The rest were driven towards Czerwień in a „death march” (10,000‑20,000 prisoners perished), into Russia. (more on: pl.wikipedia.org [access: 2013.08.17])

06.1941 massacres (NKVD): After German attack of Russian‑occupied Polish territory and following that of Russia itself, before a panic escape, Russians murdered — in accordance with the genocidal order issued on 24.06.1941 by the Russian interior minister Lawrence Beria to murder all prisoners (formally „sentenced for counter–revolutionary activities', anti–Russian acts', sabotage and diversion, and political prisoners 'in custody'), held in NKVD‑run prisons in Russian occupied Poland, Lithuania, Latvia and Estonia — c. 40,000‑50,000 prisoners. In addition Russians murdered many thousands of victims arrested after German attack regarding them as „enemies of people” — those victims were not even entered into prisons’ registers. Most of them were murdered in massacres in the prisons themselves, the others during so‑called „death marches” when the prisoners were driven out east. After Russians departure and start of German occupation a number of spontaneous pogroms of Jews took place. Many Jews collaborated with Russians and were regarded as co‑responsible for prison massacres. (more on: en.wikipedia.org [access: 2021.09.20])

Ribbentrop-Molotov: Genocidal Russian–German alliance pact between Russian leader Joseph Stalin and German leader Adolf Hitler signed on 23.08.1939 in Moscow by respective foreign ministers, Mr. Vyacheslav Molotov for Russia and Joachim von Ribbentrop for Germany. The pact sanctioned and was the direct cause of joint Russian and German invasion of Poland and the outbreak of the II World War in 09.1939. „The war was one of the greatest calamities and dramas of humanity in history, for two atheistic and anti–Christian ideologies — national and international socialism — rejected God and His fifth Decalogue commandment: Thou shall not kill!” (Abp Stanislaus Gądecki, 01.09.2019). The decisions taken — backed up by the betrayal of the formal allies of Poland, France and Germany, which on 12.09.1939, at a joint conference in Abbeville, decided not to provide aid to attacked Poland and not to take military action against Germany (a clear breach of treaty obligations with Poland) — were on 28.09.1939 slightly altered and made more precise when a treaty on „German–Russian boundaries and friendship” was agreed by the same murderous signatories. One of its findings was establishment of spheres of influence in Central and Eastern Europe and in consequence IV partition of Poland. In one of its secret annexes agreed, that: „the Signatories will not tolerate on its respective territories any Polish propaganda that affects the territory of the other Side. On their respective territories they will suppress all such propaganda and inform each other of the measures taken to accomplish it”. The agreements resulted in a series of meeting between two genocidal organization representing both sides — German Gestapo and Russian NKVD when coordination of efforts to exterminate Polish intelligentsia and Polish leading classes (in Germany called Intelligenzaktion, in Russia took the form of Katyń massacres) where discussed. Resulted in deaths of hundreds of thousands of Polish intelligentsia, including thousands of priests presented here, and tens of millions of ordinary people,. The results of this Russian–German pact lasted till 1989 and are still in evidence even today. (more on: en.wikipedia.org [access: 2015.09.30])

Polish-Russian war of 1919—20: War for independence of Poland and its borders. Poland regained independence in 1918 but had to fight for its borders with former imperial powers, in particular Russia. Russia planned to incite Bolshevik–like revolutions in the Western Europe and thus invaded Poland. Russian invaders were defeated in 08.1920 in a battle called Warsaw battle („Vistula river miracle”, one of the 10 most important battles in history, according to some historians). Thanks to this victory Poland recaptured part of the lands lost during partitions of Poland in XVIII century, and Europe was saved from the genocidal Communism.
