On the contrary, the Cavalry must never allow itself to be influenced in its movements by the position of its own Artillery. The latter must adapt itself unconditionally to the movements of the former, and must endeavour to conform to its evolutions, so as not only to co-operate with it, but, if possible, to dispense with a special escort. It must, therefore, be the endeavour of the Artillery to keep well out in front of the Cavalry, so as to take the enemy under fire, and anticipate his batteries by coming into action first. The latter is a most important point, for it is the essential duty of the enemy's gunners to divert and beat down the fire which we endeavour to bring against their horsemen. If we can only succeed in unlimbering first, they are bound to accept the law from us, and are thereby prevented either of availing themselves of the advantages of the ground or of conforming to the tactical intentions of their Leader. The best position for Artillery must always be behind some sheltering roll of the ground, where it requires none, or at the most a weak, escort; and this desideratum will be best fulfilled when it is on the inner--that is, the supported--flank of its Cavalry, because in this position it can presumably remain in action longest, and hampers the movements of its own force least. Similarly, in pursuit or in covering a retreat its sphere of activity is distinctly limited. Its action can only then become effective when the actual tactical pursuit--_i.e._, with cold steel--ceases, the combatants have disentangled themselves, and the strategic pursuit sets in. The mobility of the target must naturally influence the fire effect to be expected from the guns, as it increases the difficulty of 'ranging,' and limits the possible duration of action to a few moments. The batteries will only then be able to turn their fire on the enemy's Cavalry when the latter show themselves in considerable masses moving at the slower paces. But when the Cavalry sweep forward at full speed, the most they can do will be to take some stretch of ground through which the opposing Cavalry must pass, and on which there is still time to range, and then turn on shrapnel fire to its utmost intensity. But even for this the opportunity will only then arise when either our own Cavalry holds back, the enemy's Artillery does not require our full attention and fire power, or, finally, if our own guns are not attacked by the enemy's Cavalry. In view of all these considerations, it follows that it is impossible to assign a decisive importance to the participation of a few Horse Batteries in the actual shock of the opposing squadrons. Nevertheless, one should always do one's best to use to the utmost such Artillery power as is available, and particularly if there is any doubt as to the strength of the enemy, and we have reason to suspect that he possesses a marked numerical superiority.
