All this time you insisted that Maurice suggests charging only at a trot basing on this quote from the tagma drills sections. And let's assume you are right. What is the trot then? Trot can assume different speeds and according to wikipedia
So depending on the breed and intensity and it can be anything from slow to fast. Napoleonic Era sources also describe a fast trot:
Maurice also refers to trot as "not too fast". So what is exactly the trot in speed metrics?
The trot's actual speed does vary, but the Standardbred was a breed developed in the 17th century, well after Maurice's time, and for only one purpose. It is a literal racing horse.
The ERE of Maurice's time used a wide range of horseflesh of various breeds, with equally varying intelligence, gait and temperament. Many of the breeds are extinct -- such as the Nisean -- but their known descendants don't have any particularly exceptional troting characteristics that I'm aware of. So I'd assume it would be more or less a standard trot.
And that leads me to another question: how do you picture a charge with a trot? If it is a slow trot charge which is basically almost walking pace, what purpose did it serve? Do you not think they used their momentum to literally break the formation? If not then what? And if they did, do you not think that a slow trot wouldn't be enough?
Note: this is borrowing heavily from Keegan's Face of Battle.
It (the cataphract charge) was used like a steamroller.
The tagma's closed-ranks were key to gaining its own momentum. The close order, in addition to protection from ranged weapons, served to prevent men from falling back or shying away, forcing them so close together that no one could be anywhere except where he was supposed to be. Presenting a fully armored front that could shrug off arrows, practically resist heavier thrown missiles and beat aside pikes or spears arrayed against them, the men in the first rank freely and liberally used their weapons at hand once within reach. At first, with their lances, but rapidly shifting to axes, swords and maces if the infantry tried to stand their ground and didn't immediately back away.
(The majority did not try to stand their ground.)
Assuming the infantry tried to stand, a horse wins a shoving match even at a trot and even moreso when the rider is making an earnest effort to kill you at the same time. As the first infantry gave ground (or were made to give ground; dead men don't hold), they would disorder their own formation. Even in the case of the men bravely facing the cataphracts there would be a no man's land quickly established that marked the lancer's reach, which would make a tagma-shaped hole through their formation. Not impromptu gaps through which one or two horses might pass but as wide as the entire formation of cavalry. If the formation were, for whatever reason, narrower than the tagmas charging then the men receiving would begin to "ooze" out; left, right and to the rear.
To their left and right, there are other tagmas doing the same thing, until the options left to the infantry are only to the rear.
The men in the following ranks of the tagma were horse archers, but not much less armored than the lancers, and supported the attack by way of producing a veritable rain of arrows (Maurice stresses rate of fire as the most important aspect of the archer's performance, far above accuracy) on the approach that would have an obvious disturbing effect on infantry. Once their lancers in front were in amongst the infantry (assuming it got that far without the infantry breaking and running) the archers then switched to their own lances and sidearms but were probably restricted to opportunistic swipes -- they were still in close-order after all and possibly enough deep within their own formation that the only viable target would be unfortunate strays.
At any rate, nobody willingly stands in front of a steamroller and if they do, well... in the end it is all the same.
Again, how do you picture the charge that penetrates a formation and pushes through to the rear?
The infantry moves out of the way and horses go through the gaps created, mostly.
