When the Swedes and Saxons, under Gustavus and the Elector of Saxony, drew near to the Imperial army under Tilly, in the neighbourhood of Leipsic, there was a crisis, a thrill of worldwide expectation, as when the Armada approached the shores of England; as when the allies met the forces of Louis XIV. at Blenheim, as when, on those same plains of Leipsic, the uprisen nations advanced to battle against Napoleon. Count Tilly's military genius fell short only of the highest. His figure was one which showed that war had become a science, and that the days of the Paladins were past. He was a little old man, with a broad wrinkled forehead, hollow cheeks, a long nose and projecting chin, grotesquely attired in a slashed doublet of green satin, with a peaked hat and a long red feather hanging down behind. His charger was a grey pony, his only weapon a pistol, which it was his delight to say he had never fired in the thirty pitched fields which he had fought and won. He was a Walloon by birth, a pupil of the Jesuits, a sincere devotee, and could boast that he had never yielded to the allurements of wine or women, as well as that he had never lost a battle. His name was now one of horror, for he was the captor of Magdeburg, and if he had not commanded the massacre, or, as it was said, jested at it, he could not be acquitted of cruel connivance. That it was the death of his honour to survive the butchery which he ought to have died, if necessary, in resisting sword in hand, is a soldier's judgment on his case. At his side was Pappenheim, another pupil of the Jesuits, the Dundee of the thirty years' war, with all the devotion, all the loyalty, all the ferocity of the Cavalier, the most fiery and brilliant of cavalry officers, the leader of the storming column at Magdeburg. In those armies the heavy cavalry was the principal arm. The musket was an unwieldy matchlock fired from a rest, and without a bayonet, so that in the infantry regiments it was necessary to combine pikemen with the musketeers. Cannon there were of all calibres and with a whole vocabulary of fantastic names, but none capable of advancing and manoeuvring with troops in battle. The Imperial troops were formed in heavy masses. Gustavus, taking his lesson from the Roman legion, had introduced a more open order--he had lightened the musket, dispensed with the rest, given the musketeer a cartridge box instead of the flapping bandoleer. He had trained his cavalry, instead of firing their carbines and wheeling, to charge home with the sword. He had created a real field artillery of imperfect structure, but which told on the Imperial masses.
