When a _squadron_, acting independently in reconnaissance, as advanced guard, flank guard, or divisional cavalry, finds itself obliged to attack, it will, as a rule, employ its whole force simultaneously, whether it charges in line, knee to knee, or uses a troop in single rank as first line. If a troop has been thrown forward as advanced guard, it must quickly clear the front, and endeavour to join the squadron, so as to strengthen it before the collision, and not to become prematurely involved in a disadvantageous fight. The squadron is generally too weak to carry out an offensive fight on foot. There is also no means of guarding the led horses but by patrols. If they should become isolated during the attack, there will be a danger of losing them, especially in hostile country. A squadron must therefore only determine on a dismounted attack when such action is absolutely unavoidable. For dispersing hostile patrols or armed inhabitants, about a troop dismounted will generally suffice, where there is no opportunity of surprising them in the charge, or of enveloping them. A defensive fight on foot must not be undertaken by a single squadron unless absolutely necessary, or which the led horses can be disposed in a safe place in the immediate neighbourhood, where the flanks cannot be turned, or where the arrival of reinforcements can be relied upon. A squadron attacking knee to knee is stronger than a numerically superior enemy who charges in looser formation and is not armed with the lance. The _regiment_ of four or five squadrons is numerically too weak a body to be able of itself to carry out the larger strategical missions. It will therefore operate in more or less close co-operation with other troops, and will seldom be called upon to fight independently. It may, however, find itself for a time obliged to rely upon its own fighting strength, whether acting as divisional cavalry, as advanced guard, or as a detachment from a larger force of cavalry. If a fight is in immediate prospect, column of troops must first be formed from column of route, and a broader front, which will allow of a rapid assumption of the attack formation, must then be adopted according to the ground. In the charge against cavalry the regiment should only on rare occasions deploy all its squadrons into line, but must, whenever practicable, detail one squadron to follow in second line, and another in forward échelon, to protect the more exposed flank and to turn that of the enemy.
