It is singular to see a man like Guibert, with practical ideas on most things, give a long dissertation to demonstrate that the officers of his time were wrong in aiming at the middle of the body, that is, in firing low. He claims this is ridiculous to one who understands the trajectory of the rifle. These officers were right. They revived the recommendations of Cromwell, because they knew that in combat the soldier naturally fires too high because he does not aim, and because the shape of the rifle, when it is brought to the shoulder, tends to keep the muzzle higher than the breech. Whether that is the reason or something else, the fact is indisputable. It is said that in Prussian drills all the bullets hit the ground at fifty paces. With the arms of that time and the manner of fighting, results would have been magnificent in battle if the bullets had struck fifty paces before the enemy instead of passing over his head. Yet at Mollwitz, where the Austrians had five thousand men disabled, the Prussians had over four thousand. Firing with a horizontal sector, if the muzzle be heavy, is more deadly than firing with a vertical sector. 4. Marches. Camps. Night Attacks. From the fact that infantry ought always to fight in thin formation, scattered, it does not follow that it ought to be kept in that order. Only in column is it possible to maintain the battle order. It is necessary to keep one's men in hand as long as possible, because once engaged, they no longer belong to you. The disposition in closed mass is not a suitable marching formation, even in a battalion for a short distance. On account of heat, the closed column is intolerable, like an unventilated room. Formation with half-distances is better. (Why? Air, view, etc.) Such a formation prevents ready entry of the column into battle in case of necessity or surprise. The half-divisions not in the first line are brought up, the arms at the order, and they can furnish either skirmishers or a reserve for the first line which has been deployed as skirmishers. At Leuctra, Epaminondas diminished, by one-half, the depth of his men; he formed square phalanxes of fifty men to a side. He could have very well dispensed with it, for the Lacedaemonian right was at once thrown into disorder by its own cavalry which was placed in front of that wing. The superior cavalry of Epaminondas overran not only the cavalry but the infantry that was behind it. The infantry of Epaminondas, coming in the wake of his cavalry finished the work. Turning to the right, the left of Epaminondas then took in the flank the Lacedaemonian line. Menaced also in front by the approaching echelons of Epaminondas, this line became demoralized and took to flight. Perhaps this fifty by fifty formation was adopted in order to give, without maneuver, a front of fifty capable of acting in any direction. At Leuctra, it simply acted to the right and took the enemy in the flank and in reverse.
