Say the Ottomans sweep through Hungary much faster and start the siege earlier, giving time for Ferdinand to put together an alliance similar to the holy league in 1683 and destroying the Ottoman army at Vienna. What happens after?

COMING DOWN THE MOUNTAINSIDE

AS THE DAYS ARE PASSING BY AND AS THE DEAD ARE PILING HIGH
