But the strongest pledge for the success of his undertaking Gustavus found in himself. Prudence demanded that he should embrace all the foreign assistance he could, in order to guard his enterprise from the imputation of rashness; but all his confidence and courage were entirely derived from himself. He was indisputably the greatest general of his age, and the bravest soldier in the army which he had formed. Familiar with the tactics of Greece and Rome, he had discovered a more effective system of warfare, which was adopted as a model by the most eminent commanders of subsequent times. He reduced the unwieldly squadrons of cavalry, and rendered their movements more light and rapid; and, with the same view, he widened the intervals between his battalions. Instead of the usual array in a single line, he disposed his forces in two lines, that the second might advance in the event of the first giving way. He made up for his want of cavalry, by placing infantry among the horse; a practice which frequently decided the victory. Europe first learned from him the importance of infantry. All Germany was astonished at the strict discipline which, at the first, so creditably distinguished the Swedish army within their territories; all disorders were punished with the utmost severity--particularly impiety, theft, gambling, and duelling. The Swedish articles of war enforced frugality. In the camp, the king’s tent not excepted, neither silver nor gold was to be seen. The general’s eye looked as vigilantly to the morals as to the martial bravery of his soldiers; every regiment was ordered to form round its chaplain for morning and evening prayers. In all these points the lawgiver was also an example. A sincere and ardent piety exalted his courage. Equally free from the coarse infidelity which leaves the passions of the barbarian without control; and from the grovelling superstition of Ferdinand, who humbled himself to the dust before the Supreme Being, while he haughtily trampled on his fellow creature--in the height of his success he was ever a man and a Christian; in the height of his devotion a king and a hero.
