To direct operations with lines far removed from each other, and without communications, is to commit a fault which always gives birth to a second. The detached column has only its orders for the first day. Its operations on the following day depend upon what may have happened to the main body. Thus, this column either loses time upon emergency, in waiting for orders, or it will act without them, and at hazard. Let it therefore be held as a principle, that an army should always keep its columns so united as to prevent the enemy from passing between them with impunity. Whenever, for particular reasons, this principle is departed from, the detached corps should be independent in their operations. They should move toward a point fixed upon for their future junction. They should advance without hesitating, and without waiting for fresh orders; and every precaution should be taken to prevent an attack upon them in detail.
NOTE.
The Austrian army, commanded by Field-marshal Alvinzi, was divided into two corps, destined to act independently, until they should accomplish their junction before Mantua. The first of these corps, consisting of forty-five thousand men, was under the orders of Alvinzi. It was to debouch by Monte Baldo, upon the positions occupied by the French army on the Adige. The second corps, commanded by General ProvÉra, was destined to act upon the lower Adige, and to raise the blockade of Mantua. Napoleon, informed of the enemy’s movements, but not entirely comprehending his projects, confined himself to concentrating his masses, and giving orders to the troops to hold themselves in readiness to manoeuvre. In the meantime, fresh information satisfied the general-in-chief of the French army that the corps which had debouched by La Coronna, over Monte Baldo, was endeavoring to form a junction with its cavalry and artillery—both which, having crossed the Adige at Dolce, were directing their march upon the plateau of Rivoli, by the great road leading by Incanole.
Napoleon immediately foresaw that, by having possession of the plateau, he should be able to prevent this junction, and obtain all the advantages of the initiative. He accordingly put his troops in motion, and at two o’clock in the morning occupied that important position. Once master of the point fixed upon for the junction of the Austrian columns, success followed all his dispositions. He repulsed every attack, made seven thousand prisoners, and took several standards and twelve pieces of cannon. At two o’clock in the afternoon, the battle of Rivoli was already gained, when Napoleon, learning that General ProvÉra had passed the Adige at Anghiari, and was directing his march upon Mantua, left to his generals the charge of following up the retreat of Alvinzi, and placed himself at the head of a division for the purpose of defeating the designs of ProvÉra.
By a rapid march, he again succeeded in the initiatory movement, and in preventing the garrison of Mantua from uniting its force with the relieving army. The corps intrusted with the blockade, eager to distinguish itself under the eyes of the conqueror of Rivoli, compelled the garrison to retire into the place, while the division of Victor, forgetting the fatigues of a forced march, rushed with impetuosity on the relieving army in front. At this moment a sortie from the lines of St. George took him in flank, while the corps of Augereau, which had followed the march of the Austrian general, attacked him in rear. ProvÉra, surrounded on all sides, capitulated. The result of these two battles cost the Austrians three thousand men in killed and wounded, twenty-two thousand prisoners, twenty-four standards, and forty-six pieces of cannon.
