Looks like the Poles are taking on the survival of Civilization yet again, as the Poles saved Europe from the Moslems at Vienna, 1529. Jan III Sobieski in 1529 saved Europe from the moslems, and Duke Henry II of Silesia saved Europe from Gengis Khan at Liegnitz on April 9, 1241.
The forces of the darkness shall not prevail.
Here is a link to a good page on the the battle at All Empires.
"You have dates mix stop somehow; Jan our king of Rzeczposplita was in XVII century; battle of Vienna took place in 1683"
"Jan III Sobieski was born in Olesko, Galicja on June 2, 1624 and died 72 years later on June 17,1696. He was a native Pole of noble blood, who through his mother inherited the Ziolkowski fortune, and through his father - Jakub Sobieski- the enormous Sobieski estates. He was one of the wealthiest nobles in Poland, who later augmented his fortune by marrying Maria Kazimiera d'Arquien, the widow of John Zamoyski.
Sobieski studied at the University of Krakow and traveled all over Europe. He fought in the Cossack insurrection and helped expel the Swedes from Poland. For his services and accomplishments he was given the title of the Commander in Chief of the army.
One of Sobieski's ambitions was to unify the Christian Europe in a crusade to drive the Turks out of Europe. He organized the Holy League to preserve the Christendom. In 1683, in alliance with the Holy Roman Emperor Leopold I , he led the army that defeated the Turks in Vienna, which turned out to be a great victory and made the Polish King a hero to all of Christian Europe."
