KL Neuengamme: German concentration camp, initially fillial to KL Sachsenhausen, later independent. Prisoners were used as slaves in various munitions factories. On 18.04.1945 Germans started evacuation and forced prisoners into so‑called „Death Marchers”. Some were locked in a few ships in Hamburg port. The port was bombed by Allies and most of the prisoners perished. (more on: pl.wikipedia.orgClick to attempt to display webpage

KL Groß-Rosen: Groß‑Rosen (today: Rogoźnica) was a German concentration camp founded in the summer of 1940 (first transport of prisoners arrived on 02.08.1940). Initially a branch of KL Sachsenhausen concentration camp. In 1944 became a centre of a network of more than 100 camps. Prisoners were forced to slave at nearby granite quarries, on starvation rations. More than 125,000 prisoners were enslaved — 40,000 victims perished. In 1945 — in „death marches” — Germans dragged through the camp thousands of prisoners from the camp’s in east being one by one overrun by the Russians. The camp itself was captured by the Russians on 14.02.1945. (more on: en.wikipedia.orgClick to attempt to display webpage

KL Auschwitz: German KL Auschwitz concentration camp (Germ. Konzentrationslager) and death camp (Germ. Vernichtungslager) camp was set up by Germans around 27.01.1940 n. Oświęcim, on the German territory (initially in Germ. Provinz Schlesien — Silesia Province; and from 1941 Germ. Provinz Oberschlesien — Upper Silesia Province). Initially mainly Poles were interned. From 1942 it became the centre for holocaust of European Jews. Part of the KL Auschwitz concentration camps’ complex was death camp (Germ. Vernichtungslager) KL Auschwitz II Birkenau, located not far away from the main camp. There Germans murder possibly in excess of million people, mainly Jews, in gas chambers.

Radom: The prison in Radom was established in 1817 by the Russian authorities (during partitions of Poland) and operated in the building of the former convent of the Benedictine Sisters. After the start of the German occupation in 09‑10.1939, Germans categorized the prison as a so‑called independent judicial prison, generally supervised by the Justice Department of the Government of the General Governorate, and within the district — by the Justice Department of the Governor's Office of the District of Radom. It was called interchangeably Germ. „Gefängnis Radom” (Eng. „Prison in Radom”) and Germ. „Deutsche Strafanstalt Radom" (Eng. „German prison in Radom”). The prison had three departments: women's, criminal, German, and from the end of 1942, the Germ. „Sonderabteilung” (Eng. „Special department”) managed by the German political police Gestapo. During the World War II, c. 18,000 people — mostly political prisoners — passed through it (14,170 files of inmates have survived). At least several thousand were murdered or taken to concentration camps. The prison operated under German supervision until c. 15.01.1945 (the last transport sent to KL Auschwitz left on 14.01.1945 — it only reached Częstochowa, and the rest of the prisoners were murdered by the Germans). After the end of the military operations of World War II and the beginning of the Russian occupation in 1945, members of Polish independence organizations were held there. On 09.09.1945 armed underground units (Freedom and Independence WiN and National Military Organization NOW, consisting of former members of the Home Army AK, „Jodła" region — part of the former Polish Clandestine State) commanded by Stefan Bembiński „Harnas", freed 292 inmates, including 60 former Home Army AK soldiers arrested by a unit of the Commie–Nazi Security Office of the UB (subordinate to the Russian NKVD).

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
