Before all things, it is essential that any reserves still available should be sent forward in the directions important for pursuit as soon as it is judged that the battle is won, and that their supply should be arranged for before the pursuit begins.

I may cite the battle of Woerth as an example. The 4th Cavalry Division stood at the disposal of the commander. Observation troops were sufficient in the direction of Hagenau and Zabern. This cavalry mass was, however, only brought up late in the evening, and arrived on the field too late to take up the immediate pursuit, although it had long been realised that a pursuit would become necessary.

The infantry pursuit failed for different reasons. At the end of the day, when success inclined to the Germans, a fresh Württemberg brigade arrived upon the battlefield. Hot fighting still raged about Fröschweiler, in which the whole of the Vth and XIth Corps were involved. The Crown Prince, with a right appreciation of the situation, sent forward this brigade in a parallel pursuit against the right wing of the French in the direction of Reichshofen, where it could have denied the exit at Zabern to the French. This brigade, however, allowed itself to be deflected from its objective, and involved in the fighting round Fröschweiler, the capture of which was no longer of any real importance from the point of view of the Head Quarters.

If the affair is practically decided, as was the case at Woerth, the reserves still in hand should no longer allow themselves to be drawn towards the various foci of the battle, but must be sent forward by the Commander-in-Chief with boldness and determination in the now more decisive directions of the pursuit.

The same reasons and principles hold good for the pursuit by the cavalry.

The cavalry commander must continually keep his finger on the pulse of the battle, and not watch only that portion of the great drama which is being played under his own eyes.

Should the scales of victory incline in favour of his own army, if he considers that the intervention of his cavalry will no longer be necessary to complete the victory, he will often be well advised to renounce his share in the decisive battle, at least by a charge which would entail heavy loss, and to husband all his force for the pursuit, and to prepare and make dispositions for it. This consideration is of especial importance for that portion of the army cavalry which is concentrated on the flank, as to it must chiefly fall the task of pursuit.

Great attention should be paid, even during the battle, to nursing the horses. They should be fed, not from the small reserve of forage carried on the saddle, but from wagons, which can be easily sent to the flank of the army, emptied, and used later for the transport of the wounded. It is of great importance that these measures should be taken in good time. The forage carried will be needed during the pursuit, for supplies for the horses cannot be reckoned upon in country where armies have been on the move. It will even be advisable to take forage wagons with the pursuing force itself. When the maintenance of physical strength has thus been cared for, the next step is to push patrols and squadrons rapidly forward to reconnoitre the outer lines of retreat of the enemy. While these have been ascertained, the march in pursuit must be undertaken without hesitation, and continued even during the night. While daylight in any way allows, attempts will naturally be made to attack the withdrawing enemy in flank, and to carry disorder into his columns. As soon, however, as darkness falls and puts an end to the fighting, the march should be continued on parallel lines throughout the whole night, if possible in constant touch with the enemy, in order that he may again be attacked at dawn the next morning, or that his retreat may be barred at defiles or other favourable places. The trophies of pursuit will rarely fall into the hands of him who shrinks from spending the night after the battle marching, or neglects to prepare in every way for such an operation.

Direct frontal pursuit by the cavalry will generally yield but meagre results against the masses of the modern army and the firearm of the present day. Only when completely demoralised troops are retreating in the open, and cannot be reached by fire, will a charge be feasible. Generally, however, the frontal cavalry pursuit will be soon brought to a standstill by the hostile occupation of localities, woods and the like. Frontal pursuit is essentially a matter for the infantry, who must press the retreating enemy to the utmost. On the other hand, it is of course the duty of the cavalry to maintain touch with the enemy under all circumstances. With this object in view it must continue the frontal pursuit, sometimes even without seeking to draw on a fight, by day and night. When the strength of the infantry fails, it is the imperative duty of the cavalry to continue to harass the foe. In conjunction with the artillery it should be able to inflict considerable losses on the opponent. In the face of modern conditions, however, too great results must not be expected from such action.

When the army cavalry undertakes a frontal pursuit, it will be advisable to divide it by brigades, to which must be allotted the various roads along which the enemy is retreating. To each column must be assigned artillery, to enable it to be continually at grips with the enemy. Cases may also occur where, if the enemy's lines of retreat are not too close together, it will be possible to penetrate between them, and thus strike all the terrors of a parallel pursuit to the very heart of his army. The results that might thus be gained will justify great risks.
