Remember 9/11
From July 14 to September 11, 1683, Vienna endured the siege of a vast Turkish army under the Turkish Serasker (Supreme Commander), Grand Vizier Kara Mustafa.
After fending off 18 major Turkish assaults, only a third of the originally 11,500-strong garrison in Vienna remained fit for combat and their munitions were nearly exhausted.
The Holy Roman Emperor, Leopold I, called for help. Responding were Imperial troops and additional forces from Saxony, Bavaria, Baden, Franconia and Swabia.
The opposing military forces were those of the Ottoman Empire and Ottoman fiefdoms commanded by Grand Vizier Mustafa Pasha.
The King of Poland, John Sobieski, led the relief forces and defeated Mustafa Pasha.
The attack on the World Trade Towers occurred 328 years later on September 11, 2017.
