".... to the other 9-11: September 11th, 1683, the day when an alliance of Christian armies led by Jan III Sobieski, the King of Poland, arrived at the Gates of Vienna.
.. at the last possible moment on the evening of September 11th, that Jan Sobieski arrived at a hill north of the city, leading a force of 40,000 Poles and their German and Austrian allies. The battle began soon afterwards, in the early morning hours of September 12th.."
