4. The guards of infantry have different objects, and are differently stationed: their duty is, to receive and support the guards of cavalry in cases of need: to protect the troops sent out for wood, forage, or water; in short to prevent any approaches from the small parties of the enemy. Some are stationed in the churches or the neighboring villages, in barns, houses, and in passages and avenues of woods: others are stationed on the borders of rivulets, and in every place necessary to secure the _camp_. Guards that are stationed in churches, in woods or among trees, barns, and houses, should if possible, be seen from the army, or at least from some grand guard in its neighborhood, that signals may be readily perceived and repeated. 5. The guards of infantry are generally fixed; that is, they have the same post both day and night, except such as are to support and protect the guards of cavalry, and to cover the forage grounds. All out-guards should have intrenching-tools with them. 6. The guards of cavalry have generally a day-post and a night-post; the latter is seldom more than 4 or 500 paces from the _camp_; one third should be mounted, one third bridled, and one third feeding their horses; but when near the enemy, the whole guard should be kept mounted during the night. 7. The security and tranquillity of a _camp_ depending upon the vigilance of the guards, the officers who command them cannot be too active in preventing surprises: a neglect in this particular is often of fatal consequence. Though an officer should, at all times, be strictly attentive to every part of the service, yet he should be more particularly watchful in the night than in the day. The night is the time most favorable for surprises: as those who are not on duty, are generally asleep, and cannot immediately afford assistance; but in the day time, the attention of all the troops is turned to the movements of the enemy: they are sooner under arms, sooner in readiness to march, and in much less danger of being thrown into confusion.
