Okay, it’s too late for this year’s commemorations. It’s never too late to get accurate and relevant history.
WordPress’s feature that leads to posts with similar tags pointed me to a couple of posts that mention the Siege of Vienna of 1683, another September 11 conflict between nations chiefly Moslem on one side, with nations chiefly Christian on the other. Is it a great revelation that the study of European history is weak in U.S. schools, generally, and that many Americans have no clue about such events?
My old friend Jim Bencivenga and I spent a few lunches (a couple? They stuck with me, anyway) discussing those battles that were great turning points in history — battles where, had they gone the other way, the whole of history would have been quite different. The Siege of Vienna is one such history-turning incident, and those sites will introduce you to it well.
Nota bene: A reader alerted me to some questionable material in the blogs I had originally linked to. I’ve replaced those links with a link to the Wikipedia article on the battle, at least until I further check out the blogs.
