It is a correct principle to vary these exercises, which should be gone through sometimes in one place and sometimes in another, and should sometimes be shorter and sometimes longer in duration. The horse will take much more kindly to them if you do not confine him to one place and one routine. Since it is a matter of prime necessity that the rider should keep his seat, while galloping full speed on every sort of ground, and at the same time be able to use his weapons with effect on horseback, nothing could be better, where the country suits and there are wild animals, than to practise horsemanship in combination with the chase. But when these resources fail, a good exercise may be supplied in the combined efforts of two horsemen. (9) One of them will play the part of fugitive, retreating helter-skelter over every sort of ground, with lance reversed and plying the butt end. The other pursues, with buttons on his javelins and his lance similarly handled. (10) Whenever he comes within javelin range he lets fly at the retreating foeman with his blunted missiles; or whenever within spear thrust he deals the overtaken combatant a blow. In coming to close quarters, it is a good plan first to drag the foeman towards oneself, and then on a sudden to thrust him off; that is a device to bring him to the ground. (11) The correct plan for the man so dragged is to press his horse forward: by which action the man who is being dragged is more likely to unhorse his assailant than to be brought to the ground himself. (9) {ippota}. A poetic word; "cavaliers." (10) Or, "manipulated." (11) Or, "that may be spoken off as the 'purl trick'"; "it will unhorse him if anything." If it ever happens that you have an enemy's camp in front, and cavalry skirmishing is the order of the day (at one time charging the enemy right up to the hostile battle-line, and again beating a retreat), under these circumstances it is well to bear in mind that so long as the skirmisher is close to his own party, (12) valour and discretion alike dictate to wheel and charge in the vanguard might and main; but when he finds himself in close proximity to the foe, he must keep his horse well in hand. This, in all probability, will enable him to do the greatest mischief to the enemy, and to receive least damage at his hands. (12) See "Hipparch," viii. 23.
