This very important arm is the eye with which the general sees for many

miles to the front and flank. In an advance it pushes ahead, combs the

country for the enemy, disperses his cavalry, and thus protects the

infantry in the rear. It locates the enemy, and occupies his attention

until the infantry comes up. It protects the flanks and rear of the

infantry and artillery during the fight. If needed, it joins in the

fight. If the infantry is defeated it covers the withdrawal, and if the

infantry wins it pursues and pounces upon the enemy.
