KL Dachau: KL Dachau in German Bavaria, set up in 1933, became the main concentration camp for Catholic priests and religious during II World War: Germans imprisoned there approx. 3,000 priests, including 1,800 Poles. They were forced to slave at so‑called „Plantags”, doing manual field works, at constructions, including crematorium. In the barracks ruled hunger, freezing cold in the winter and suffocating heat during the summer. Prisoners suffered from bouts of illnesses, including tuberculosis. Many were victims of murderous „medical experiments” — in 11.1942 c. 20 were given phlegmon injections; in 07.1942 to 05.1944 c. 120 were used by for malaria experiments. More than 750 Polish clerics where murdered by the Germans, some brought to Schloss Hartheim euthanasia centre and murdered in gas chambers. At its peak KL Dachau concentration camps’ system had nearly 100 slave labour sub–camps located throughout southern Germany and Austria. There were c. 32,000 documented deaths at the camp, and thousands perished without a trace. C. 10,000 of the 30,000 inmates were found sick at the time of liberation, on 29.04.1945, by the USA troops… (more on: www.kz-gedenkstaette-dachau.de [access: 2013.08.10], en.wikipedia.org [access: 2016.05.30])

Intelligenzaktion: (Eng. „Action Intelligentsia”) — extermination program of Polish elites, mainly intelligentsia, executed by the Germans right from the start of the occupation in 09.1939 till around 05.1940, mainly on the lands directly incorporated into Germany but also in the so‑called General Governorate where it was called AB‑aktion. During the first phase right after start of German occupation of Poland implemented as Germ. Unternehmen „Tannenberg” (Eng. „Tannenberg operation”) — plan based on proscription lists of Poles worked out by (Germ. Sonderfahndungsbuch Polen), regarded by Germans as specially dangerous to the German Reich. List contained names of c. 61,000 Poles. Altogether during this genocide Germans methodically murdered c. 50,000 teachers, priests, landowners, social and political activists and retired military. Further 50,000 were sent to concentration camps where most of them perished. (more on: www.kz-gedenkstaette-dachau.de [access: 2013.08.10], en.wikipedia.org [access: 2016.05.30], en.wikipedia.org [access: 2014.10.04])

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])
