The officer detaches the Serjeant's Troop to the right, the Corporal's and four men to the left, and himself remains with his men in the centre. The Serjeant sends two men to the skirts of the wood; these must look at the tracks, and one of them ride on a height, if any is near; the remainder divide themselves to the left of these two men, at such a distance that they can keep each other in sight. The Corporal divides his men in the same manner from the Right Flank of the Column to the Officer's Troop. If the Officer perceives that these two lines are not extensive enough to cover the ground towards his Troop, he detaches a sufficient number of men to the right and left to form a perfect line, which line must be careful never to get at the head of the Column. The Non-commissioned officers endeavor to keep their men in the same line with the Officer's Division. It sometimes excites pity to see the men unnecessarily gallop and fatigue their horses on such occasions, only from want of instructions, without doing more good than they would have done at a walk. SECTION II. PATROLLING A WOOD. This is done in the same manner as if (Section I.,) a Side Patrol meets with a wood, with the difference that two men are likewise sent round to the left extremity of the wood. SECTION III. PATROLS OF DISCOVERY Consists generally of a pretty considerable force, to be enabled to defend themselves against a small hostile party or patrol, and are sent for the purpose of ascertaining whether a certain place is in the Enemy's possession, whether he is on the move against us, or whether a certain district is occupied by him. Such a Patrol marches, after having passed the chain of Videttes, with the ordinary precautions of having three men for Advanced, and two for Rear Guard, and sends, in case the country requires it, one man to the right, and another to the left, on the heights. As not unfrequently the safety, but also the attainment of the object for which the Patrol was sent out, depends upon its not being seen by the Enemy, before the Patrol has discovered him, it is of the utmost importance to instruct the men at the head very accurately, they must not merely be satisfied with looking before them, but look at the tracks of the cross-roads very minutely, and mount every hill with caution, &c. If this is done, the Patrol will sometimes have opportunities to make prisoners. When a Patrol sees the Enemy advance towards it with not too strong a force, it must try to conceal itself and rapidly attack the unsuspecting enemy: he will get into confusion, fly, and perhaps lose some prisoners. If the Enemy has been discovered before, but is too strong, the Patrol retires: is perhaps not seen by him at all; and circumstances may allow that it is able to continue its march, and to obtain the object of its first destination. All these advantages are lost when the Enemy discovers it.
