Frederick the Great, a general above all others ever ready for battle, and who almost directed his army in battle by word of command, never required strong outposts. We see him therefore constantly encamping close under the eyes of the enemy, without any great apparatus of outposts, relying for his security, at one place on a hussar regiment, at another on a light battalion, or perhaps on the pickets, and supports furnished from the camp. On the march, a few thousand horse, generally furnished by the cavalry on the flanks of the first line, formed his advanced guard, and at the end of the march rejoined the main body. He very seldom had any corps permanently employed as advanced guard.
When it is the intention of a small army, by using the whole weight of its mass with great vigour and activity, to make the enemy feel the effect of its superior discipline and the greater resolution of its commander, then almost every thing must be done sous la barbe de l’ennemi, in the same way as Frederick the Great did when opposed to Daun. A system of holding back from the enemy, and a very formal, and extensive system of outposts would neutralise all the advantages of the above kind of superiority. The circumstance that an error of another kind, and the carrying out Frederick’s system too far, may lead to a battle of Hochkirch, is no argument against this method of acting; we should rather say, that as there was only one battle of Hochkirch in all the Silesian war, we ought to recognise in this system a proof of the King’s consummate ability.
Napoleon, however, who commanded an army not deficient in discipline and firmness, and who did not want for resolution himself, never moved without a strong advanced guard. There are two reasons for this.
The first is to be found in the alteration in tactics. A whole army is no longer led into battle as one body by mere word of command, to settle the affair like a great duel by more or less skill and bravery; the combatants on each side now range their forces more to suit the
