A Dismounted Sentry who is able to see the movements of the several Videttes, and who can acquaint the Picquet with them, is a measure so necessary for the safety of the Picquet, that it never ought to be omitted. One-third or one-fourth of the horses are always bridled up and ready to advance; the men must never take off their swords and belts; one-half of them may sleep in the middle of the day, the other in the afternoon, that they may be all perfectly alert at night. The men must not be allowed to go into houses or villages in the neighbourhood; such straggling leads to irregularities, and on being rapidly attacked by the enemy the horses will be lost. When the men water their horses, they must bridle them up, and take everything with them; none but inexperienced and negligent Officers will allow the men to water their horses at any distance with merely the halter on, and leaving the bridle with the Picquet. In short, a Picquet must at all times be ready for an attack in half a minute. How often the Picquets are to patrol, where to and how far, is generally ordered by the Officer commanding the outposts. If there are no orders upon these subjects, the following Patrols will be sent: The first at half an hour before daybreak, or so early that it has time to arrive at the place of its destination at daylight; here it will remain until it is full daylight. Whoever leads the Patrol is to go up on the top of a hill, where he can look about to a considerable distance, and then he returns, the second Patrol at ten o'clock; the third at two o'clock; the fourth towards evening; the fifth at midnight. This arrangement, however, depends upon the distance of the enemy, except the morning Patrol before daylight, which is to go under all circumstances. It cannot be too frequently told to all Patrols, that they are often to look to the rear when they return. The Enemy very frequently succeeds in following a negligent Patrol of this kind, and surprising the Picquet, which thinks itself perfectly secure. In a close country it is very advisable after the return of a patrol, to send forward again a few men at the distance of a mile, to be certain that the Enemy did not follow the Patrol. _By Night._ The proper time for the Picquet to go to the night post is when it gets too dark for the day Videttes to see at any distance; they are then called in, and the position for the night is taken up. If there are any apprehensions of being betrayed to the enemy by spies or inhabitants of the country, it is advisable to change the spot again, but the Videttes will remain. In case the enemy is very near, the Picquet must be mounted; this is, however, very fatiguing for men and horses; it is, therefore, better to cause one-third or one-half to mount and to advance about a hundred yards; the remainder is to stand by their horses.
