Line or column will be reformed on the same principles, the caution being LINE ON NO. --, _or_ COLUMN _or_ QUARTER COLUMN ON NO. --, on which the named company if in movement, will be halted. =118.= _Meeting an attack by cavalry or swordsmen._ When a battalion in line is threatened by cavalry or swordsmen in force, it may sometimes be desirable to dress back the threatened flank and to dress up the unmenaced flank, the battalion commander giving the order BACK, NO. --, UP, NO. --. =119.= _Formation of Squares._ 1. In savage warfare, it may often be necessary to form a square two deep. This can be formed from line on the two centre companies, the companies further to the flanks forming the side faces, and the flank companies the rear face, all, except the companies nearest the two centre companies, moving into position by fours. On the caution ON THE TWO CENTRE COMPANIES FORM--SQUARE, the commanders of the two centre companies will take post for firing. Nos. 3 and 6 will turn about, and at the halt right and left form at the double, and turn about by order of their commanders. The remaining companies, by order of their commanders, will form fours inwards, and the commanders of the two centre companies will order their companies to fix bayonets. Nos. 2, 7 will then be moved at the double to the points where their flanks will rest in square, on the left or right form up at the halt, turn about. Nos. 1 and 8 will halt and turn to the left and right respectively to form the rear face. The company officers and supernumeraries who are outside will pass into the square. Each company as it reaches its position will be ordered to fix bayonets. The company commanders will give orders as to firing, subject to directions from the commanding officer. If there are an odd number of companies, that next to the right flank company should double inside the square, form column of half-companies, and fix bayonets. Line may be reformed by reversing the above movements. On the command REFORM--LINE, the company commanders will give the order to unfix bayonets, and form or march their companies on to the original alignment at the double; Nos. 3 and 6 receiving the word _Left_ and _Right Form_ respectively, the remainder forming fours. 2. Square will be formed from column as follows:--On the word FORM--SQUARE, the leading company, if on the march will be halted, and bayonets will be fixed. The remainder will be moved at the double by order of their commanders, and those which are to form the side faces will be formed successively to the right and left, the last company forming the rear face. Each company as it reaches its position will be ordered to fix bayonets. If there is an uneven number of companies in the battalion, the rear company but one will form company column on the march, halt inside the square and fix bayonets.
