137. The company being in line of battle, and at a halt, when the instructor shall wish to cause it to march by the right flank, he will command:
1. Company, right—FACE. 2. Forward. 3. MARCH.
138. At the first command, the company will face to the right, the covering sergeant will place himself at the head of the front-rank, the captain having stepped out for the purpose, so far as to find himself by the side of the sergeant, and on his left; the front-rank will double, as is prescribed in the S. S., No. 363; the rear-rank will, at the same time, side-step to the right one pace, and double in the same manner; so that when the movement is completed, the files will be formed of four men aligned, and elbow to elbow. The intervals will be preserved.
139. The file closers will also move by side step to the right, so that when the ranks are formed, they will be two paces from the rearmost rank.
140. At the command march, the company will move off briskly in quick time; the covering sergeant at the head of the front-rank, and the captain on his left will march straight-forward. The men of each file will march abreast of their respective front-rank men, heads direct to the front; the file closers will march opposite their places in line of battle.
141. The instructor will cause the principles of the march by the flank to be observed, in placing himself, pending the march, as prescribed in the S. S., No. 368.
142. The instructor will cause the march by the left flank to be executed by the same commands, substituting left for right; the ranks will double, as has been prescribed in the S. S., No. 365; the rear-rank will side-step to the left one pace before doubling.
143. At the instant the company faces to the left, the left guide will place himself at the head of the front-rank; the captain will pass rapidly to the left, and place himself by the right side of this guide; the covering sergeant will replace the captain in the front-rank, the moment the latter quits it to go to the left.
