In making arrangements with regard to outpost cavalry, attention should be paid to reducing the distance which messages have to be carried. In this respect, horses are not always sufficiently considered. When outpost companies are pushed out far to the flank, it would usually be well to observe the instructions of the "Field Service Manual," and to detail small detachments of cavalry to the companies for their independent use, as this will prevent considerable waste of strength. It will often be necessary, on the other hand, to protect unsupported flanks of a line of infantry outposts by special detachments of the divisional cavalry that do not form part of the outpost cavalry. Such detachments would, if possible, find housing for themselves and be self-protecting, though they might, under certain circumstances, be given a small force of infantry for local security.
It is most important that the outpost cavalry should be concentrated in good time in the morning before the commencement of the march or of the engagement, and that they should retire in formed order on the divisional cavalry. This requires careful preparation and instructions; some practical method must be found which will overcome the difficulties that now present themselves. The various squadron commanders must act in conjunction with the officers commanding the outposts. All the higher officers, and those directing the manœuvres, must, however, always keep this matter in mind, so that the present system, which offers such serious disadvantages, may not become so customary as to be carried on in time of war.
Having examined the flaws still to be found in our outpost system, and which are likely to adversely affect the arm in war, we find, on turning to the sphere of reconnaissance, that such defects are even more prevalent.
The arrangements that are usually made in this matter often draw on the strength of the cavalry in a manner quite out of proportion to the demands of actual war, and weaken the squadrons to such an extent as almost to destroy their fighting value. The weak point is, in the main, as follows:
It is usual for every order given by a commanding officer to direct that a reconnaissance should be carried out, even though the previous order may have given instructions for one in the same direction. The cavalry obeys these orders, and sends out fresh patrols each time the order is repeated. As the patrols are always told to keep in touch with the enemy, and as, on account of peace conditions that obtain, nobody thinks of relieving them, they collect in one direction, whilst the squadron becomes weaker and weaker.
I consider that every effort should be made to combat this bad habit. Care should be taken not to send out unnecessary patrols, and to call in, from time to time, those that have been sent out, or where necessary, to relieve them. I believe that this would be possible if the following rules were observed.
If an order has been given which entails a reconnaissance in a certain direction, it is unnecessary that this should be repeated in a subsequent order. Other directions rather, which are indicated by reason of the altered conditions, should be brought to notice, and reference made to the reconnaissance already despatched. Under no circumstances, however, should a cavalry commander be induced, on receiving instructions to reconnoitre in a certain direction, to send a patrol to a point where he knows his patrols to be already in touch with the enemy. The necessary economy of strength can only be effected by leaving the command of the patrol service entirely in the hands of the cavalry commander, who must be responsible to his superior officer for the carrying out of the reconnaissance work entrusted to him. The superior officer should only interfere if he discovers obvious mistakes, or if other circumstances render such a step absolutely necessary. He must, for his part, see that orderlies and reporting patrols that come in remain with his staff, and that they are sent back to the squadron when opportunity offers, so as to be available for fighting purposes. This should be made a standing order at manœuvres.
All patrols that are sent out must receive definite orders as to how far they are to advance in any given direction, how long they are to reconnoitre in that direction, and when they are to return. If, at the expiration of such a period, renewed reconnaissance is found necessary in the same direction, relieving patrols should be despatched in good time, i.e. before the first patrols have returned; and these fresh patrols should, if possible, meet the returning ones, in order to exchange notes regarding the enemy. For this purpose the outward and homeward routes of the patrols should be prearranged as far as circumstances permit.
In manœuvres, when one officer takes over command from another, he must inquire as to the arrangements made for reconnaissance work, and must take measures accordingly.
When a fresh squadron is sent out on reconnaissance, due notice must be given to the squadron to be relieved. The two officers commanding must act in conjunction, so that the officer being relieved can draw in his patrols and the relieving patrols of the new squadron be sent out in good time.
