While the ranks are filling up, you must see that the horses get enough food to stand hard work, since horses unfit for their work can neither overtake nor escape. You must see that they are docile, because disobedient animals assist the enemy more than their own side. And horses that kick when mounted must be got rid of, for such brutes often do more mischief than the enemy. You must also look after their feet, so that they can be ridden on rough ground, for you know that wherever galloping is painful to them, they are useless.
