NOTE.
“When we undertake a siege,” says Montécuculli, “we should not seek to place ourselves opposite the weakest part of the fortress, but at the point most favorable for establishing a camp and executing the designs we have in view.”
This maxim was well understood by the Duke of Berwick. Sent to form the siege of Nice in 1706, he determined to attack on the side of Montalban, contrary to the advice of Vauban, and even to the orders of the king. Having a very small army at his disposal, he began by securing his camp. This he did by constructing redoubts upon the heights that shut in the space between the Var and the Paillon, two rivers which supported his flanks. By this means, he protected himself against a surprise; for the Duke of Savoy, having the power of debouching suddenly by the Col de Tende, it was necessary that the marshal should be enabled to assemble his forces, so as to move rapidly upon his adversary, and fight him before he got into position; otherwise his inferiority in numbers would have obliged him to raise the siege.
When Marshal Saxe was besieging Brussels, with only twenty-eight thousand men, opposed to a garrison of twelve thousand, he received intelligence that the Prince of Waldeck was assembling his forces to raise the siege. Not being strong enough to form an army of observation, the marshal reconnoitred a field of battle on the little river Voluve, and made all the necessary dispositions for moving rapidly to the spot, in case of the approach of the enemy. By this means he was prepared to receive his adversary without discontinuing the operations of the siege.
MAXIM XLII.
Feuquière says that “we should never wait for the enemy in the lines of circumvallation, but we should go out and attack him.” He is in error. There is no authority in war without exception; and it would be dangerous to proscribe the principle of awaiting the enemy within the lines of circumvallation.
