Napoleon I said that in battle, the role of skirmishers is the most fatiguing and most deadly. This means that under the Empire, as at present, the strongly engaged infantry troops rapidly dissolved into skirmishers. The action was decided by the moral agency of the troops not engaged, held in hand, capable of movement in any direction and acting as a great menace of new danger to the adversary, already shaken by the destructive action of the skirmishers. The same is true to-day. But the greater force of fire arms requires, more than ever, that they be utilized. The role of the skirmisher becomes preeminently the destructive role; it is forced on every organization seriously engaged by the greater moral pressure of to-day which causes men to scatter sooner. Commanders-in-chief imagine formed battalions firing on the enemy and do not include the use of skirmishers in drill. This is an error, for they are necessary in drill and everywhere, etc. The formed rank is more difficult to utilize than ever. General Leboeuf used a very practical movement of going into battle, by platoons, which advance to the battle line in echelon, and can fire, even if they are taken in the very act of the movement. There is always the same dangerous tendency toward mass action even for a battalion in maneuver. This is an error. The principles of maneuver for small units should not be confused with those for great units. Emperor Napoleon did not prescribe skirmishers in flat country. But every officer should be reduced who does not utilize them to some degree. The role of the skirmisher becomes more and more predominant. He should be so much the more watched and directed as he is used against more deadly arms, and, consequently, is more disposed to escape from all control, from all direction. Yet under such battle conditions formations are proposed which send skirmishers six hundred paces in advance of battalions and which give the battalion commander the mission of watching and directing (with six companies of one hundred and twenty men) troops spread over a space of three hundred paces by five hundred, at a minimum. To advance skirmishers six hundred paces from their battalion and to expect they will remain there is the work of people who have never observed.
