Salvete Omnes,
let us take trip to the XVIII century Europe with an expert-   
and so we will return  to  a Prussian cavalry general 
Charles E. de Warnery, whom I quoted in my  posts in the past,  and these are  some of his observations about military horsemen and horses of his days:
" For a soldier to be really a light horseman, he must be able to turn his horse quick
 and short, when in full speed, to raise up and catch any thing from the
 ground;
he will find himself much firmer in his seat, have greater 
command of his horse, and much more 
agility in the exercise of his arms, & by being mounted on an 
eastern saddle, that is to say, upon a Hungarian, Turkish, or Polish 
one; to those who have been accustomed to other saddles, they appear at 
first to be inconvenient, but they very soon find themselves perfectly 
at ease in them, and ever after, prefer them to all others; they are 
very light, cheap, and durable, and do not so often require repairing as
 the others do.' 
 ''The service of light horse requiring them
 to be as it were always in presence of the enemy, and ready to mount on
 horseback in an instant; they ought not to have either breast-belts or 
cruppers to their saddles, which will enable them to saddle much quicker
 than they can do otherwise: besides, as the saddles above described 
have double girths, they are sufficiently firm without them.''
''In every species of cavalry the man ought to be proportioned to the size of his horse, and
 the arms with which he is to serve, adapted and proportioned to them 
both, and the nature of service to be performed;
thus
''...consequently the 
cuirassier should be larger, and his arms heavier than the dragoon, and 
those more so than the Light Horse or Hussars; a small man has great difficulty to mount a large horse, particularly
 with a cuirasse, they should all however be muscular and robust, but 
not heavy; the Prussian Dragoons are too heavy for their horses, and it 
is ridiculous to see a large man upon a small horse:
 which by being strained with too much weight, is very soon ruined, and 
the trooper dismounted; a man who is more than 5 feet 8 inches, ought 
not to be received into the cavalry, but will find his proper place in 
the infantry.''
When a recruit is enlisted 
he is taught to hold himself upright, to march with an easy air, and to 
shake off the lounge of the peasant; he is taught the exercise of the 
broad-sword, with small basket-hiked sticks; nothing contributes more 
towards rendering him active and dexterous; he is exercised on foot, 
until he is sufficiently prepared to begin it in the squadron. Whatever 
may be said, I hold it very essential, that cavalry soldiers, and 
particularly dragoons, should be acquainted with the exercise on foot, 
almost as well as the infantry; but always in two ranks, as the 
cuirassiers; they may also preserve their bayonets, provided they are 
not too weighty: the English and Hanoverians have taken them from their 
cavalry. It is however very advantageous that cavalry should be enabled 
to defend themselves at all times, and even on foot, if necessity 
required it,''
''It will be 
found very useful to practice on foot, at least once, any manœuvres 
which you would perform with the squadron, before you try them on 
horseback, this not only saves the horses, but very much assists the 
ready and correct conception and execution of it, particularly should it
 be an intricate or complex manœuvre.
When the recruit is sufficiently instructed on foot, he is mounted upon a wooden horse, much
 like those made use of in riding-schools for vaulting, but it must have
 a neck and head, to fix a bridle to; there should be two of those 
horses per troop, the recruits must be instructed by them how to place 
the saddle on their horses, to mount and dismount on both sides, with or
 without stirrups, how to fold his cloak, to put on his baggage, and a 
truss of forrage, to vault into the saddle without aid by the croup, 
that he might be enabled to do it on his horse, without
 having occasion for a knot instead of a stirrup; he must be exercised 
to bend forward and take his hat from the ground; to dismount, to stand 
and hold the bridle properly; in a word, every thing but vaulting; to 
place himself in every position of the exercise, to draw, handle, and 
return his sword; to load and fire his carbine and pistols; and to 
exercise and make use of his arms with spirit and address: this is the 
manner in which recruits are formed in the service, and is very nearly 
the fame that is recommended by Vegecius.  These two wooden horses should be placed as in a rencounter, on the 
right hand of each other, and those that are upon them mould thrust and 
cut with the point and with the edge, with  basketbasket-hiked sticks, and they should be taught all the guards, to ward off, and to parry the fame. ''
 ''A soldier should not be taught to ride as it is practised by professed 
riding-masters, because the greatest part of the aids given by them must
 be with the bridle, which for that purpose must be held short, but 
without stiffness, the left shoulder a little forward, extending his 
hand in an easy manner to the mane of the horse; a trooper in the ranks can give false aids only with his legs. When he has been properly exercised in this manner, his horse is
 given to him, and he is quartered with a non-commissioned officer, or 
some old steady trooper, who is to mew him how to take care of his horse, how to saddle and to bridle it, to comb his mane without tearing out the hair, and never to touch the tail but with his hand, to wash it once a week, and after 
the new moon to cut the points of the hair; experience has proved this 
to be the true means of preserving that fine ornament of a horse. Every thing should now be taught the recruit which might be requisite 
on actual service, very near the exercise of the carousel, except the 
exercise of the javelin, which would be useless to him. He ought to be 
able to turn his horse suddenly upon his haunches, to run at the
the ring with his sword instead of a lance, which very much suples the horse, and forms the trooper to dexterity and firmness in his feat, without however attending to all the minutia required in the riding academies."
''A squadron 
ought to be often exercised without saddles, and manœuvre every day at 
least half an hour: this is absolutely necessary, to keep the horses in 
wind, and to harden them; it is with them as with racers, if they are 
not kept in continual training, they are very soon incapable of 
performing the service required of them.''
''There are few horses but 
which might be made to run; when we had bought those which our Hussars 
had taken from the enemy, the greatest number of them were given in the 
re-mount; at first those troopers who receieved them where disatisfied 
with their want of activity, but after having felt the Prussian spur for
 a few weeks, they were as fleet as the others.''  
"As soon as the squadron is mounted the troopers are practised to leap ditches, enclosures, poles put across for that purpose, etc. At other times two troopers run together full speed, trying to get before and carry off each other's hats: they are practised to swim their horses across rivers, to manoeuvre in broken and intersected ground, etc.[...] and they must be made to 
trot a good deal, by which they will acquire a firm seat on horseback, 
and not to fall upon the saddle at each motion of the horse;
 they ought to ride with shorter stirrups than in the riding-schools, because they must be able to raise themselves four inches above the 
saddle.''
There are targets to be 
fired at by the troopers, with their pistols* walking, trotting, and 
full gallop, and even in leaping over a bar.
''A head of 
felt, stuffed with wool or straw, is fixed to a branch or post, which 
the soldier is to touch with the thrust or the cut, both in passing and 
repassing, in full gallop. It would very much stimulate the soldiers to 
emulation, by attaching some gratification to those who acquit 
themselves with the greatest address.''
''They should frequently be made to move briskly forward, and then suddenly halted upon the spot; at the word halt, the
 trooper presses upon his stirrups, keeping his body a little backward, 
retaining the bridle by bending his wrist a little, but without moving 
his arm; by these means he puts his horse upon his haunches.''
''A squadron 
should be accustomed to move off its ground at once, and all the 
troopers to be in motion at the fame instant, at the word of command, 
either at a walk, trot, or gallop; they should even be made to traverse 
in line. It will sometimes happen that when they are not perfect in this
 exercise, some horses will receive atteintes, or blows with their fore 
feet, from the odiers, but the performance of this manœuvre on service, 
is too important to prevent their acquiring it under any apprehensions 
of this inconvenience. It is absolutely necessary that good cavalry 
should be able to traverse, and that they should move the whole line at 
the same instant, and not successively, as I have seen it practised by 
some which has rather the appearance of counter than traverse marching; 
nothing can contribute more towards supleing of horses than the traverse
 movement. It is pityful to see a squadron be obliged to break off by 
divisions to gain ground obliquely to the right or the left, when by 
traversing this is performed in an instant, and gracefully.''
''A squadron 
ought often to be exercised in a single rank, and to advance obliquely 
to the right and left, upon a variety of alignements and points of view,
 and appui, in a rank entire; the faults are more easily discovered, and
 the trooper learns to march in line with more exactness: for which 
purpose more attention and accuracy is required, an extensive line in 
single rank being much more subject to waving than in two or three; 
sometimes even the whole regiment should manœuvre in this manner.''
''Since the lance has been 
rejected, the sword is, without contradiction, the queen of arms for the
 cavalry; and it is upon that alone, that they should depend in action, 
until the enemy is dispersed: it is only then that they might be allowed
 to make use of their pistols. Opinions are very much divided with 
regard to the advantage or superiority of the edge or the point of the 
sword for cavalry in action; each have their advocates equally zealous, 
who produce such instances as are in favour of that they prefer: but 
after much reflection on this important subject, frequent observations 
of the advantages and disadvantages of each, and some experience, during
 many years actual service in the cavalry, I hope I shall be permitted 
to mention my reasons for giving a decided preference to the latter.
''The point of the sword is 
more advantagous than the edge, because with it you can reach your enemy
 at a greater distance than with the other, the smallest wound with it 
renders the wounded incapable of serving during the remainder of the 
action at least; it does not require so much force to give a dangerous 
wound with a thrust as with a cut, and the effect of the latter. is much
 more uncertain, unless it happens to be particularly well placed, which
 it is hardly possible to do, unless you have your enemy as it were 
under your hand...''
''A squadron 
formed in two ranks is very subject to waving, and much easier broken 
than one of three, which also must naturally have a greater weight in 
the shock, and be much more difficult for an enemy to penetrate, even 
should several of the front rank be fallen or disabled: for as it causes
 no opening in the line, the horse will not fail to advance even without his rider, feeling himself pressed on each side and behind, as it always happens: for a horse must
 be very much wounded to make him fall upon the spot.
