Nature of an Offensive Action.
The normal type of an offensive battle is a methodical progression from point to point, each successive capture weakening the enemy’s hold on his main position, and paving the way for a further advance; and each successive advance being deliberately prepared and systematically carried out.
129. Distribution of Infantry in the Attack.
1. Infantry, whether in the holding or in the main attack, is formed into three bodies, distributed in depth:—
The first to develop the attack. This portion will be divided into Scouts and Firing Line, portions of which may be kept back as Supports until required.
The second to reinforce, and, if possible, to complete the attack. This portion will consist of Reserves in the hands of battalion, brigade and other commanders.
The third to be employed, if necessary, in completing an attack, to confirm a success, or meet an unforeseen emergency. This portion is termed the General Reserve, and remains at the disposal of the commander of the whole force.
2. The General Reserve should only in very special circumstances fall short of a quarter of the body to which it belongs.
On the other hand, the leading body of infantry should be as small as possible, and, exclusive of the supports, should seldom exceed a quarter of the whole.
