I was there just about one month ago, actually. Lovely place, the mountains there remind me of the Appalacians.
Two things I know about this:
1) The Turkish general was almost captured, but upon escaping was strangled to death by order of the Caliph.
2) Europeans, rushing into the Turks camps discovered a new drink still cooking on the fires: Coffee! Hence Vienna was (and is) the center of some of the world's best coffee.
Shalom!
I've heard that too.
Others I've heard follow, but they are probably just legends.
1) The croissant was invented in Vienna in 1683 to celebrate the defeat of the Turkish siege of the city, as a reference to the crescents on the Turkish flags. (This might have taken place earlier in the Siege of Vienna of 1529.)
2) A baker from Vienna made the first bagel as a gift to King Jan Sobieski to commemorate the King's victory over the Turks that year. The baked good was fashioned in the form of a stirrup to commemorate the victorious charge by the Polish cavalry.
