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.''
''...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.''
