During September 1939 other important date was
17th
Here song about this event
The September ballad by Jacek Kaczmarski
We waited so long for this day
With impatient hope in the soul
When without words Comrade Stalin
Moves with the Tobacco pipe arrows on the map
Shout fleeted along the border
And before it ceased Cannons had thundered
With the speed of storm
Red Army ran into Battle
What is that new history?
Surprised Europe will ask
How is that? These are Molotov’s boys
And Ribentropp’s allies
Their entire trail is marked with victory
Banner of Freedom covered the glory
With the heads of polish Owners
They pave entire Ukraine
Podolia falls, Volhynia pays tribute
People joyfully welcome new system
Churches and properties are on fire
And Christ with the bullet in the back of His head
They will sheer their hands on the battlefield
Into the breathtaking mutual fist
Countless children of Soso
Undefeatable Hitler’s litter
Finally Bastard of Versailles is wiped off the maps
Finally Jew and Belarusian are free
No more Polish hand
Will force them to do anything
New freedom “Pravda” Announces to them
The news spreads around entire world like a shot
That since then one banner unites
Star, sickle, hakenkreuz and hammer
History will not forget those days
When Old Continent froze in amazement
And our posterity will celebrate
After 1st of September - 17th
And our posterity will Celebrate
After 1st of September - 17th
And here this song in polish
