These helpless lines in the American Revolutionary War came into collision with the rebel troops, which certainly could not drill but could shoot so much the better in that they were fighting for their own interests and therefore did not desert like the enlisted soldiers. These did not, like the English, deploy in massed bodies on the open field, but in rapidly moving bodies of sharpshooters in the thick woods. The organised lines were here powerless and had to contend against invisible and unapproachable foes. The sharpshooters thereupon were brought into existence as a part of the army organization--a new method of fighting arising from a change in the military material. What the American Revolution began the French completed in the military realm. To the drilled troops of the Coalition the French Revolution opposed soldiers who were badly drilled but who constituted large masses, the product of the whole nation. Some means had to be discovered of protecting Paris with these masses. That could not be done without victory in the open field. A mere musketry engagement would not suffice, a form would have to be discovered by which the masses could be utilized and this was found in the column. The column formation allowed slightly drilled troops to keep better order and by means of a better marching speed (one hundred steps to the minute) allowed it to break through the stiff old-fashioned line arrangement. It was possible by this formation to fight in country unsuitable to the line formation, to mass troops in places suitable, to associate scattered sharpshooters with the columns, to keep back, occupy and wear the lines of the enemy, until the decisive movement came when a charge could be made by the troops held in reserve. This new method of combining riflemen and columns and making a complete army corps consisting of all arms, which was fully developed on its tactical and strategic side by Napoleon, was only rendered possible by the change in military material brought about by the French Revolution. There were still two very important technical preliminaries, first the making of light carriages for field pieces which were constructed by Gribevaul by means of which alone the required quick advance was rendered possible, and making the army rifle a more precise weapon by adapting to it some of the features of the hunting rifle. Without these improvements military sharpshooting would have been impossible.
