After the outbreak of World War II with the Nazi invasion of Poland, the Soviet Union also invaded Poland on September 17, as part of the Molotov-Ribbentrop Pact between Nazi Germany and Soviet Union.
Feiner was caught in the Soviet part of occupied Poland, was arrested by the NKVD and spent several months in a Soviet prison in Lida, near Wilno.
Despite the fact that before the war on several occasions he had defended Polish Communists in court as an attorney, and that he had belonged to a socialist organization (the General Jewish Labour Bund in Poland), the Soviets authorities charged him with being a "fascist" and a "counter revolutionary" After the Nazi invasion of the Soviet Union Feiner managed to escape after the Soviets fled Lida in 1941, and made his way to Nazi occupied Warsaw.
During the Nazi occupation of Poland Feiner, even though he lived in the "Aryan" side of Warsaw under the assumed name "Berezowski", was one of the central personalities of the Jewish underground in the city.
He was the author of most of the communiques of the Bund from Poland to the Western allies, in which he described Nazi terror and brutality.
Feiner also served as a guide for the Polish courier Jan Karski inside the Warsaw Ghetto (they both crossed into the ghetto through the Warsaw sewers).
Karski asked Feiner what prominent American and British Jews should do.
"Tell the Jewish leaders," Feiner said, "that ... they must find the strength and courage to make sacrifices no other statesmen have ever had to make, sacrifices as painful as the fate of my dying people, and as unique."
Karski also took Feiner's report to the Polish-Jewish political leaders Szmul Zygielbojm and Ignacy Schwarzbart, who were serving on the Polish National Council of the Polish Government-in-Exile in London.
The report described the murder of Jews by the Germans across Poland, the extermination camp at Chełmno (including the mobile gas vans) and gave the estimated number of murdered Jews, as of May, 1942, at 700,000 (the actual number was already much higher).
The description of the condition of Jews in German occupied Poland and Feiner's instructions threw Zygielbojm into depression since he knew that the Allies would be unwilling to help (Zygielbojm eventually committed suicide as a protest against the indifference of the Allied governments in the face of the Holocaust).
After the Warsaw Ghetto Uprising and the liquidation of the Ghetto by the Germans, Feiner tried desperately to help those who were sent to slave labor camps.
Leon Feiner survived the Nazi occupation, the Warsaw Ghetto Uprising and the Warsaw Uprising, and was rescued in Lublin in January 1945.
However, due to terminal illness (throat cancer) he died soon afterward, on February 22.
Even while in the hospital he maintained relationships with his friends and fellow political activists and participated in discussions of the future of the Bund in Poland.
He is buried in the main row of the Okopowa Street Jewish Cemetery in Warsaw (quarter 12). 
After the German invasion of Poland, both prototypes were not able to fly and remained in factory at Okęcie in Warsaw.
They were captured by the Germans in a damaged state, their further fate is not known.  
In the People's Republic of Poland, on 8 September 1968, Ryszard Siwiec immolated himself in Warsaw during a harvest festival at the 10th-Anniversary Stadium in protest against the Warsaw Pact's invasion of Czechoslovakia and the totalitarianism of the communist government.
Siwiec did not survive. 
Swedish invasion affected the richest provinces of the Polish–Lithuanian Commonwealth (Greater Poland, Lesser Poland, Mazovia, Pomerelia, Kujawy, Podlasie), which for the most part had not been affected by major wars for 200 years.
Professor Andrzej Rottermund, manager of the Royal Castle in Warsaw claims that the Swedish army robbed Poland of her most precious goods - thousands of works of art, books and valuables.
Most of these items have never been returned to Poland, and are kept both in private Swedish hands, and in Stockholm museums, such as Swedish Army Museum, and Livrustkammaren.
Almost all cities, towns, castles and churches in locations where Swedish troops were stationed were destroyed, and, as prof. Rottermund says, it can be seen even today, as in guides to many Polish towns and cities one will find a note that says "object destroyed during Swedish invasion".
From the Royal Castle in Warsaw Swedes stole app.
200 paintings, a number of carpets and Turkish tents, musical instruments, furniture, Chinese porcelain, weapons, books, manuscripts, marbles, even dresses of maids and door frames, pulled from walls.
Huber Kowalski of University of Warsaw Institute of Archeology says that Swedes stole anything they could lay their hands on - windows, stairs, chimneys, sculptures, floors, doors and gates.
Most goods were loaded on boats and transported along the Vistula to the Baltic Sea, and then to Sweden.
In November 2011, archeologists of University of Warsaw found app.
70 items (total weight of five tons), which probably come from Warsaw Royal Castle.
They sank in the Vistula, while being transported to Sweden.
Even though Article 9 of the Treaty of Oliva stated that Sweden should return all stolen goods, all items are still kept in Stockholm and other Swedish locations.
Several Polish kings (Jan Kazimierz, Jan III Sobieski, Stanisław August Poniatowski) sent official missions to Sweden, but without success.
In most situations, Swedish authorities claimed that they did not know where stolen goods were.
In 1911, Kraków's Academy of Science sent its own mission, which was made of renowned professors Eugeniusz Barwiński, Ludwik Birkenmajer and Jan Łoś.
In Stockholm and Uppsala they found 205 manuscripts and 168 rare Polish books, describing their foundings in a report.
In 2002, Warsaw Royal Castle organized exhibition "Eagle and Three Crowns", which presented many items stolen from Poland, and kept in Swedish museums.
After the Deluge, the Commonwealth turned into a "cultural desert".
Poland and Lithuania lost 67 libraries and 17 archives.
Of all major cities of the country, only Lwów and Gdańsk were not destroyed, and when Swedish soldiers were unable to steal an item, they would destroy or burn it.
In ruins were castles, palaces, churches, abbeys, towns and villages.
As a result of Swedish invasion, few pre-Baroque buildings remained in Poland.
Among others, Swedish troops stole such items as:  both Polish and Lithuanian state records ("Metrica Regni Poloniae"),  royal library from Warsaw,  libraries from Ujazdów Castle, Toruń, Bydgoszcz, Malbork, Poznań, Grudziądz, Gniezno, Lublin, Jarosław, Vilnius, Sandomierz, Radom, and Kraków, also archives and libraries from most towns of Royal Prussia.
Most of stolen books are kept in University Library at Uppsala, Royal Library at Stockholm, and private libraries of the Bielke, Oxenstierna, Rosenhahne, Wrangl and Brache families,  all Warsaw palaces were completely robbed - Kazanowski Palace, Ossoliński Palace, Daniłłowicz Palace, Primate Palace, Bishophoric Palace, Royal Palace and Royal Castle,  robbed and destroyed were castles and churches and almost all Polish towns, the most notable examples are Golub-Dobrzyń, Krzyżtopór, Wieluń, Krasnystaw, Wawel, Tęczyn, Lanckorona, Pieskowa Skała, Kielce, Sandomierz, Chęciny Niepołomice, Ojców, Wiśnicz, Łobzów, Kruszwica, Rabsztyn.
According to the estimates of Polish scholars I. Ihnatowicz, Z. Landau, A. Mączak and B. Zientara, the invasion of Swedish army and its allies (Brandenburg-Prussia and Transilvania), resulted in loss of 25% of population in four core Polish provinces.
Lesser Poland lost 23% of population, Mazovia 40% in villages and 70% in towns, Greater Poland 50% in villages and 60% in towns.
Royal Prussia lost some 60% of its population.
In January 2013 Marek Poznański, a Palikot Movement member of the Polish parliament announced his plan to send thousands of postcards to European politicians and journalists, in which he wants to prove that that Poland should get financial compensation from Sweden, for the destruction of the country in the deluge.
Poznański claims that in the 1660 Treaty of Oliwa, Sweden pledged to return all stolen goods, which never happened.
The MP had previously intervened at Polish Ministry of Foreign Affairs and the Ministry of Culture, he also visited the Embassy of Sweden in Warsaw.
A businessman from Warsaw, Sławian Krzywiński, joined Poznański, creating the Foundation of Reconstruction of Destruction Caused by the Swedish Invasion (Fundacja Odbudowy Zniszczeń Dokonanych w Czasie Potopu Szwedzkiego).
According to Krzywiński, looted goods are still kept in Swedish museums and private collections.
Among others, Poland lost the Braniewo Library, works of Nicolaus Copernicus, including the 1543 Nuremberg edition of De revolutionibus orbium coelestium, as well as the oldest printed text of Bogurodzica.
Krzywiński states that as act of goodwill, Swedish side should cover the cost of reconstruction of the Rawa Mazowiecka castle, which was destroyed by them in the 1650s.
