Decisive Holy League victory; the siege was broken and the Ottoman army routed
How the atlas explains it
The Ottoman army was strung out and exhausted by two months of siege and unprepared for a major relief force descending from the heights; a massive coordinated cavalry charge spearheaded by Sobieski's Polish Winged Hussars broke the Ottoman line and collapsed their morale while the garrison held the walls.
What followed
Marked the high-water mark of Ottoman expansion into central Europe; began the Habsburg reconquest of Hungary, ultimately confirmed by the 1699 Treaty of Karlowitz.
