The following formation has proved to be handy, and, if the men have been well trained, they will have no difficulty in forming up rapidly on the darkest night. Two platoons, each in single file, advance side by side, followed at about 20 paces distance by the other two platoons in the same formation. In the event of alarm, the platoons form up on the right and left respectively, and the company then stands in column of half companies in single rank at about 60 paces distance. Whatever formation is used, the front, flanks and rear must be covered by scouts, whose distance away will vary with the light. Protection in rear is very important, yet is often neglected. I have on more than one occasion seen a night operation completely disorganised by a bold attack delivered against the rear of the column by a party of the enemy, who, in the absence of scouts, had approached unnoticed. The Field Service Regulations direct that before the position of assembly is quitted the orders are to be clearly explained to all ranks, so that everyone may know: 1. The object in view and the direction of the objective. 2. The formation to be adopted at the position of deployment. 3. The part he has to play. 4. His action in case the enemy is not surprised; also that the warnings against firing, talking, striking matches, smoking, etc., are to be repeated two or three times. In training a company the prohibitions here alluded to will, of course, be most rigidly enforced at all times. It must always be remembered that as men are trained in peace so will they act in war, and the officer who, from carelessness or good nature, allows his men to disregard these obvious precautions may inculcate habits of slackness calculated to have most serious results on service. The situation of the position of deployment will depend on the strength of the attacking force, and the alertness of the enemy; the smaller the force the nearer to the enemy’s position will this point be fixed. A company can usually get within 300 yards of the enemy’s posts without difficulty. The Regulations advocate that when the position of deployment is reached the force should be formed in three lines, but with a company it is rarely advisable to have more than two. The company may be formed with two platoons in each line, or with three in the front line and one in the second, according to the extent of the position to be attacked; the front line, at any rate, should be in single rank. When deciding on the formation officers should remember that no more men should be put into the front line than are necessary for the object in view, and that the maintenance of a reserve to meet eventualities is of paramount importance. _Guiding Troops Across Country at Night._ Instructions governing the guidance of troops at night in open country are to be found in the Field Service Regulations, and in the Manual of Map Reading and Field Sketching.
