Minas Morgul Cavalry

"Before them went a great cavalry of horsemen moving like ordered shadows, and at there head was one greater than all the rest: a rider, all in black, save that on his hooded head he wore a helm like a crown that flickered with a perilous light."

- The Two Towers: "The Stairs of Cirith Ungol"

The Morgul Knights are a type of horse based cavalry from Minas Morgul who rode out with The Lord of The Nazgul on order by Sauron to lead his armies to war. It is hard to say whether they are infact a type of horse-riding orc, men, or both; or whether if men they may be either easterlings or southrons, or infact men unique to Minas Morgul itself, possibly of Black Numenorean origin, much like the Mouth of Sauron.

It's even possible that they are men of a mixed ethnecity, as a result of mixing possible Black Numenoreans with Men from Harad and Rhun.

Appearances
. Lord of The Rings Two Towers: They were said to be riding out from Minas Morgul with The Witch-King himself ahead of them, while Frodo watches.

. Lord of The Rings Return of The King (Possibly): During Farimir's retreat to Minas Tirith after the Battle of Osgiliath it was said that "Horsemen of The Enemy"  charged toward them with the orcs following their lead, implying that they may be the same horsemen from Minas Morgul. But it was also stated that Haradrim were present, and among them was a "Mounted Champion"  implying that either the horsemen were a southron cavalry, with possible orc-horse riders (As stated that the orcs themselves have a few horsemen on their first assault) or that there may infact have been more than two battalions of horsemen at that moment, one cavalry from Minas Morgul, and the other from Harad. So they might have been present durring the attack on Osgiliath, as well as the Battle of Pelennor Fields.

 

Adaptations
While the Morgul Knights did not make an appearance in any of Peter Jackson's Films, They were however added to several mods for The Battle for Middle-Earth game franchise, including the Edain Mod.



They were also added to the Lord of The Rings Strategy Battle Game, which may have been the inspiration for fan-based units in the Battle for Middle Earth Mods.

In those games they're armor appear to be similar to that of The Mouth of Sauron, suggesting a black numenorean influence. They carry either swords or spears, and they're horses are also well-armored, similar to real horse armor durring the middle-ages and one could even argue that the morgul knights are a corrupted reflection of the knights of gondor, in particular Dol Amroth.
