Why cover the front everywhere? If you do, then what advantage is there in being able to see from a great distance? Leave large intervals between your deployed companies. We are no longer only one hundred meters from the enemy at the time of firing. Since we are able to see at a great distance we do not risk having the enemy dash into these intervals unexpectedly. Your skirmisher companies at large intervals begin the fight, the killing. While your advance companies move ahead, the battalion commander follows with his formed companies, defilading them as much as possible. He lets them march. If the skirmishers fight at the halt, he supervises them. If the commanding officer wishes to reenforce his line, if he wants to face an enemy who attempts to advance into an interval, if he has any motive for doing it, in a word, he rushes new skirmishers into the interval. Certainly, these companies have more of the forward impulse, more dash, if dash is needed, than the skirmishers already in action. If they pass the first skirmishers, no harm is done. There you have echelons already formed. The skirmishers engaged, seeing aid in front of them, can be launched ahead more easily. Besides, the companies thrown into this interval are a surprise for the enemy. That is something to be considered, as is the fact that so long as there is fighting at a halt, intervals in the skirmish lines are fit places for enemy bullets. Furthermore, these companies remain in the hands of their leaders. With the present method of reenforcing skirmishers--I am speaking of the practical method of the battlefield, not of theory--a company, starting from behind the skirmishers engaged, without a place in which to deploy, does not find anything better to do than to mingle with the skirmishers. Here it doubles the number of men, but in doing so brings disorder, prevents the control of the commanders and breaks up the regularly constituted groups. While the closing up of intervals to make places for new arrivals is good on the drill ground, or good before or after the combat, it never works during battle.
