"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." -Manuel II Paleologus
Aside from the 9/11 connection, there's a lot of other ironic & other trivia with respect to both the battle & its hero:
While Polish chauvinists would claim this as an almost exclusively "Polish" triumph, Poles - not to slight their highly valued contribution otherwise - actually made up a minority of Sobieski's fighting force; thus making "Vienna 9/11/83" a victory truly belonging to all Christendom.
Ethnic Ukrainians & troops from the Balic area were well represented as were both Scots & Irish forces.
This is the 'Celtic warrior' connection and, yes, it's reported the pipes were appropriately played both during & after the battle.
The significant involvement of the Scots is particularly interesting as it's claimed, a couple of generations later, Jan Sobieski's line intermarried with the legitimate Royal House of Scotland.
Another noteworthy claim is that Sobieski marched his army a full 2 days out of their way while otherwise rushing to lift the siege of Vienna so all could pray before the sacred image of Poland's "Black Madonna" and accordingly afterward credited & dedicated the victory to Our Lady.
At the more mundane level, even the lowly the bagel may well have been invented to honor Sobieski & celebrate the victory. OY !!!
Excellent yet alarming historical map.
