In any case, endeavour must be made so to dispose the squadron that the chief avenues of communication, at least, will be under observation, and thus closed to the enemy's despatch-riders. The horses also must be rested, that they may be ready for the next day's work, for a tired squadron cannot reconnoitre properly. In order that the horses may really rest, they must be off-saddled, and, to do this, the squadron must be secure from surprise. This will not always be possible, but endeavours must be made towards that end. Should hostile detachments be in the neighbourhood, which is unavoidable during critical days, it will be necessary to be always ready for possible surprise, and to so arrange that the squadron can speedily withdraw from its bivouac on the approach of the enemy. The measures taken for safety must be directed to this end. It is also sometimes desirable, in order to deceive the enemy, to change the halting-place already occupied, after darkness sets in. In friendly country, if an attack is expected, it is often better to spend the night in larger villages, where the inhabitants themselves will co-operate in the service of security. In the enemy's country, on the other hand--where the hostility of the inhabitants is to be reckoned with--the larger villages must always be avoided, and accommodation must be sought in single isolated farms, which, by their position, are in a measure secure from surprise, where the fighting force can be kept together, where there is nothing to fear from the inhabitants, and which can be quickly abandoned, if possible, unobserved. The service of security in such situations must be carefully organised and must not consist merely of guarding the immediate environs. It will rather be advisable to push forward posts on the chief lines of approach of the enemy, which will be able to bring in timely news of his advance. What degree of readiness for movement is maintained in such situations the circumstances of the moment must dictate. In this question of accommodation, attention must also be paid to the service of communication. It must be possible from the position selected for the night to pick up communication with our own troops and to receive the orders and instructions which will naturally be expected at the end of the day.
