NOTE.
It was a saying of Marshal Villars, that when war is decided on, it is necessary to have exact information of the number of troops the enemy can bring into the field, since it is impossible to lay down any solid plan of offensive or defensive operation without an accurate knowledge of what you have to expect and fear. “When the first shot is fired,” observes Marshal Villars, “no one can calculate what will be the issue of the war. It is, therefore, of vast importance to reflect maturely before we begin it.” When once, however, this is decided, the marshal observes that the boldest and most extended plans are generally the wisest and the most successful. “When we are determined upon war,” he adds, “we should carry it on vigorously and without trifling.”
MAXIM VI.
At the commencement of a campaign, to advance or not to advance, is a matter for grave consideration; but when once the offensive has been assumed, it must be sustained to the last extremity. However skilful the manœuvres in a retreat, it will always weaken the morale of an army, because, in losing the chances of success, these last are transferred to the enemy. Besides, retreats always cost more men and materiel than the most bloody engagements; with this difference, that in a battle the enemy’s loss is nearly equal to your own—whereas in a retreat the loss is on your side only.
