NOTE.
This was the manœuvre practised by General Desaix, in 1798, near Radstadt. He made up for inferiority in numbers by audacity, and maintained himself the whole day in position in spite of the vigorous attacks of the Archduke Charles. At night he effected his retreat in good order, and took up a position in the rear.
It was in accordance, also, with this principle, in the same campaign, that General Moreau gave battle at Biberach, to secure his retreat by the passes of the Black mountains. A few days after, he fought at Schliengen with the same object. Placed in a good defensive position, he menaced the Archduke Charles by a sudden return to the offensive, while his artillery and baggage were passing the Rhine by the bridge of Huningen, and he was making all the necessary arrangements for retiring behind that river himself.
Here, however, I would observe, that the execution of such offensive demonstrations should be deferred always till toward the evening, in order that you may not be compromised by engaging too early in a combat which you cannot long maintain with success.
Night, and the uncertainty of the enemy after an affair of this kind, will always favor your retreat, if it is judged necessary; but, with a view to mask the operation more effectually, fires should be lighted all along the lines, to deceive the enemy and prevent him from discovering this retrograde movement, for in a retreat it is a great advantage to gain a march upon your adversary.
MAXIM XXIV.
Never lose sight of this maxim: that you should establish your cantonments at the most distant and best-protected point from the enemy, especially where a surprise is possible. By this means you will have time to unite all your forces before he can attack you.
