If the weapons were nearly alike, preserving ranks and thereby breaking down, driving back and confusing the ranks of the enemy, was to conquer. The man in disordered, broken lines, no longer felt himself supported, but vulnerable everywhere, and he fled. It is true that it is hardly possible to break hostile lines without doing the same with one's own. But the one who breaks through first, has been able to do so only by making the foe fall back before his blows, by killing or wounding. He has thereby raised his courage and that of his neighbor. He knows, he sees where he is marching; whilst the adversary overtaken as a consequence of the retreat or the fall of the troops that were flanking him, is surprised. He sees himself exposed on the flank. He falls back on a line with the rank in rear in order to regain support. But the lines in the rear give way to the retreat of the first. If the withdrawal has a certain duration, terror comes as a result of the blows which drive back and mow down the first line. If, to make room for those pushed back, the last lines turn their backs, there is small chance that they will face the front again. Space has tempted them. They will not return to the fight. Then by that natural instinct of the soldier to worry, to assure himself of his supports, the contagion of flight spreads from the last ranks to the first. The first, closely engaged, has been held to the fight in the meantime, under pain of immediate death. There is no need to explain what follows; it is butchery. (Caedes). But to return to combat. It is evident that the formation of troops in a straight line, drawn close together, existed scarcely an instant. Moreover each group of files formed in action was connected with the next group; the groups, like the individuals, were always concerned about their support. The fight took place along the line of contact of the first ranks of the army, a straight line, broken, curved, and bent in different directions according to the various chances of the action at such or such a point, but always restricting and separating the combatants of the two sides. Once engaged on that line, it was necessary to face the front under pain of immediate death. Naturally and necessarily every one in these first ranks exerted all his energy to defend his life. At no point did the line become entangled as long as there was fighting, for, general or soldier, the effort of each one was to keep up the continuity of support all along the line, and to break or cut that of the enemy, because victory then followed. We see then that between men armed with swords, it was possible to have, and there was, if the combat was serious, penetration of one mass into the other, but never confusion, or a jumble of ranks, by the men forming these masses.
