I was idly watching youtube videos earlier and hit on this one "A historian reacts to Sabaton's Winged Hussars". 
https://www.youtube.com/watch?v=Jc45t2-ODlA (content warning for battle scenes, gore and horse stunts).

Now I'm not a fan of X reacts to Y videos in general, but Winged Hussars is a catchy tune and I thought I'd give it a chance - for those who don't know it, it's about the relief of Vienna by the Holy League during the Ottoman siege of 1683, spearheaded by the Polish Winged Hussars (elite heavy cavalry), culminating in the (alleged) largest cavalry charge in history - 18,000 men and horses.

I'm not impressed by his historian credentials given one of his points was "Believe it or not there were Muslim soldiers fighting on the side of the Holy League, I don't know exactly why" - it took me literally two minutes to find out these were the Lipka, aka Polish, Tatars. The clue's in the name (actually they mostly lived in Lithuania, but this is the time of the Polish-Lithuanian Commonwealth). This is basic research. He's also pretty ropey on the historical extent of the Roman Empire and brings up the post battle quote "Venimus, vidimus, Deus vicit" ("We came, we saw, God conquered"), but hasn't bothered to note down who said it (Polish King John III Sobieski). If your research doesn't extend to reading the wiki article, do you really get to call yourself a historian?

However, his main point wasn't actually a historical one, what he really wanted to do was to analogize the Siege of Vienna to the Siege of Minas Tirith in Lord of the Rings, and the arrival of the Holy League/charge of the Winged Hussars, to the Ride of the Rohirrim. And that sort of stands up. There's definitely a comparison to be made, but he seems to be going further and saying this is Tolkien's inspiration. Another comment suggests he also has a video linking Verdun and Helms Deep, so this seems to be his thing. 

Mind you, I think he misses another obvious analogy, between the Winged Hussars and the charge of the Swan Knights of Dol Amroth at the Battle of the Pelennor Fields.

But if the linkage stands - and I would love to know if anything in the Tolkien papers backs it - then the Christians vs Muslims nature of the conflict does  reinforce the analysis put forward by various people of LotR having problematic elements of a yellow-peril narrative.
