Warsaw (Szucha Ave.): At 25 John Christian Szucha Avenue in Warsaw — then in German–occupied General Governorate — at the heart of so‑called police district (with status Germ. „Nur für Deutsche” — End. „Only for Germans”), from 07.10.1939 headquarters of Germ. Der Kommandeur Sicherheitspolizei und des Sicherheitsdienst für den Distrikt Warschau (Eng. Bureau of Security Police and Security Service Commander for Warsaw District), Germans organised Warsaw HQ of Germ. Geheime Staatspolizei (Eng. Secret State Police), i.e. Gestapo. In the basements a Germ. Hausgefängnis (Eng. Detention Centre) was set. Prisoners from Warsaw prisons, mainly Pawiak (twice a day) where brought there for interrogations. Tortures were widely used — „beating (with a club, whip, rubber, iron poles, butts of pistols), kicking, setting dogs on, burning flesh with cigarettes or an iron rod (especially the face, heels and abdomen), crushing fingers and genitals, hanging on the hands at the back, breaking bones, knocking out front teeth, damaging eyeballs, strangling with a gas mask with a damaged absorber, irritating with electric current, pouring water into the nose with gagged mouth, dipping the prisoner's head in a bucket with water and holding it there until signs of suffocation, plucking out nails and driving steel needles under them” (Wikipedia). Often tortures were done with family members present. Even women in last months of pregnancy were tortured. During Warsaw Uprising of 08‑10.1944 Germans conducted mass executions in the building. Number of victims — unknown (in 06.1946 in Szucha Avenue building basements 5.5. tons of human ashes and bones were discovered). (more on: en.wikipedia.orgClick to attempt to display webpage

Pawiak: Investigative prison in Warsaw, built by the Russian occupiers of Poland in 1830‑5. During the Poland partition's period, a Russian investigative prison, both criminal and political. During World War II and the German occupation, the largest German prison in the General Government. Initially, it was subordinate to the Justice Department of the General Governorate, and from 03.1940 Germ. Sicherheitspolizei und des Sicherheitsdienst (Eng. Security Police and Security Service) of the Warsaw District — in particular the German Secret Political Police Gestapo. c. 3,000 prisoners were kept in Pawiak permanently, of which about 2,200 in the men's unit and c. 800 in the women's unit (the so‑called Serbia) — with a „capacity” of c. 1,000 prisoners. In total, in the years 1939–1944, c. 100,000 Poles passed through the prison, of which c. 37,000 were murdered in executions — from 10.1943 Pawiak prisoners were murdered in open executions on the streets of Warsaw (sometimes several times a day) — during interrogations, in cells or in a prison „hospital”, and c. 60,000 were taken in 95 transports to concentration camps (mainly KL Auischwitz), other places of isolation or to forced labor.

General Governorate: A separate administrative territorial region set up by the Germans in 1939 after defeat of Poland, which included German‑occupied part of Polish territory that was not directly incorporate into German state. Created as the result of the Molotov–Ribbentrop Pact, in a political sense, was to recreate the German idea of 1915 (after the defeat of the Russians in the Battle of Gorlice in 05.1915 during World War I) of establishing a Polish enclave within Germany (also called the General Governorate at that time). It was run by the Germans till 1945 and final Russian offensive, and was a part of so–called Big Germany — Grossdeutschland. Till 31.07.1940 formally known as Germ. Generalgouvernement für die besetzten polnischen Gebiete (Eng. General Governorate for occupied Polish territories) — later as simply niem. Generalgouvernement (Eng. General Governorate). From 07.1941 expanded to include district Galicia. (more on: en.wikipedia.orgClick to attempt to display webpage

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. In a political sense, the pact was an attempt to restore the status quo ante before 1914, with one exception, namely the „commercial” exchange of the so–called „Kingdom of Poland”, which in 1914 was part of the Russian Empire, fore Eastern Galicia (today's western Ukraine), in 1914 belonging to the Austro–Hungarian Empire. Galicia, including Lviv, was to be taken over by the Russians, the „Kingdom of Poland” — under the name of the General Governorate — Germany. The resultant „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.orgClick to attempt to display webpage

Pius XI's encyclicals: Facing the creation of two totalitarian systems in Europe, which seemed to compete with each other, though there were more similarities than contradictions between them, Pope Pius XI issued in 03.1937 (within 5 days) two encyclicals. In the „Mit brennender Sorge” (Eng. „With Burning Concern”) published on 14.03.1938, condemned the national socialism prevailing in Germany. The Pope wrote: „Whoever, following the old Germanic–pre–Christian beliefs, puts various impersonal fate in the place of a personal God, denies the wisdom of God and Providence [...], whoever exalts earthly values: race or nation, or state, or state system, representatives of state power or other fundamental values of human society, […] and makes them the highest standard of all values, including religious ones, and idolizes them, this one […] is far from true faith in God and from a worldview corresponding to such faith”. On 19.03.1937, published „Divini Redemptoris” (Eng. „Divine Redeemer”), in which criticized Russian communism, dialectical materialism and the class struggle theory. The Pope wrote: „Communism deprives man of freedom, and therefore the spiritual basis of all life norms. It deprives the human person of all his dignity and any moral support with which he could resist the onslaught of blind passions [...] This is the new gospel that Bolshevik and godless communism preaches as a message of salvation and redemption of humanity”... Pius XI demanded that the established human law be subjected to the natural law of God , recommended the implementation of the ideal of a Christian state and society, and called on Catholics to resist. Two years later, National Socialist Germany and Communist Russia came together and started World War II. (more on: www.vatican.vaClick to attempt to display webpage
