In the face of the German attack, Polish military units withdrew to the east. On 06.09.1939, the last Polish units passed through Kłecko, blowing up, among other things, the railway bridge. Earlier, on 04.09.1939, the administrative authorities, headed by the mayor, left Kłecko.

«Intelligenzaktion»: German: «Intelligenzaktion» (English: „Intelligence Action”) — a German program of extermination of the Polish elite, mainly the intelligentsia and leadership layers, carried out from the beginning of the occupation in w 09.1939 to 04.1940, mainly in territories directly annexed to Germany, but also in the so‐called Germ. Generalgouvernement (Eng. General Governorate), where it was called «AB‐aktion». In the first phase, immediately after the beginning of the German occupation, during military operations carried out by the Germ. Wehrmacht (Eng. Armed Forces) and the genocidal units of the Germ. Einsatzgruppen (Eng. Operational Groups) of the Germ. Sicherheitspolizei (Eng. Security Police), i.e. SiPo, and Germ. Sicherheitsdienst des Reichsführers SS (Eng. Security Service of the Reichsführer SS), i.e. SD, organized by the Germ. Reichssicherheitshauptamt (Eng. Reich Main Security Office), i.e. RSHA, which followed the troops, carried out under the Germ. Unternehmen „Tannenberg” (Eng. Operation „Tannenberg”) — based on the so‐called Germ. Sonderfahndungsliste (Eng. Special Wanted Lists), i.e. proscription lists of Poles considered particularly dangerous to the Third Reich, prepared by the Zentralstelle II/P (Polen) unit of the German RSHA. Later, implemented by the German civilian occupation authorities and the genocidal unit of the Germ. Volksdeutscher Selbstschutz (Eng. Ethnic Germans Self‐Defense), whose members were Germ. Volksdeutsche (Eng. Ethnic Germans), i.e. representatives of the German minority in Poland. According to various sources, these lists, at the beginning of 09.1939, could have contained the details of 61,000—88,000 „dangerous” Poles — although these figures cannot be confirmed. In total, during this genocide, c. 50,000 teachers, Catholic priests, representatives of the landed gentry, freelancers, social and political activists, and retired military personnel were systematically and methodically murdered. Another 50,000 were sent to concentration camps, where only a negligible percentage survived. (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 World War II 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 Stanislav 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
