You know BB it is not secret in Poland.
The same as who murdered Gen Nil you can watch good movie about it.
The charges against her were initiated by the Commission for Investigating Crimes against the Polish Nation, which claimed that Wolińska was an "accessory to a court murder", classified as a Stalinist crime, and is punishable by up to 10 years in prison. The case attracted international attention.Wolińska-Brus died 26 November 2008
and here is his dauther talking about ethnic grup of people who murdered him :
I don't care if it is popular subject in the world but you can't change facts.
Wolińska was born in a Polish Jewish family in Warsaw,
Lt. Col. Helena Wolińska-Brus (1919-2008) (born as Fajga Mindla Danielak) was a military prosecutor in Poland with the rank of lieutenant-colonel (podpułkownik), involved in Stalinist regime show trials of the 1950s. She has been implicated in the arrest - and in some cases death - of key figures in Poland's anti-Nazi resistance.
It wasn't mith ... and I am not accusing anny ethnic group.
As to WWII: /wiki/Rescue_of_Jews_by_Poles_during_the_Holocaust
Polish Jews were the primary victims of the German Nazi-organized Holocaust. Throughout the German occupation of Poland, many Polish gentiles - at great risk to themselves and their families - rescued Jews from the Nazis. Evidence indicates there were more Polish rescuers than people from any other nation.
As to Germans: /wiki/Occupation_of_Poland_(1939-1945)
Over 6 million Polish citizens - nearly 21.4% of the pre-war population of the Second Polish Republic - died between 1939 and 1945. Over 90% of the death toll involved non-military losses, as most civilians were targets of various deliberate actions by the Germans and Soviets.
Both occupiers wanted not only to gain Polish territory, but also to destroy Polish culture and the Polish nation as a whole
Losses by ethnic group were 3,100,000 Jews; 2,000,000 ethnic Poles
Nothing makes your responisiblity for ethnic Poles killed lower.
