Place: Vienna and the KahlenbergEra: The Great Turkish War

In July 1683 the largest Ottoman army in a generation reached Vienna. The emperor left the city; Count Starhemberg stayed to defend it with its garrison and citizens.
Two months
Ottoman engineers dug mines under the walls and blew breaches in them, and the defenders closed each one. By September the city was close to falling.
The relief
On 12 September a relieving army of imperial, German and Polish troops came down from the Kahlenberg, the hill above the city. By evening the siege was broken. Printers all over Europe sold pictures of the day for years.
