The cannonading ending, Tilly left the shelter of the heights and advanced upon the Swedes. But so hot was their fire that he filed off towards the right and fell impetuously upon the Saxons, whose ranks quickly broke and fled before the fierce charge. Of the whole force of the elector only a few regiments held their ground, but these did so in a noble manner that saved the honor of Saxony. So confident now was Tilly of victory that he sent off messengers in all haste to Munich and Vienna with word that the day was his. He was too hasty. The unbroken army of Sweden, the most thoroughly drilled body of soldiers then in Europe, was still to be dealt with. Pappenheim, who commanded the imperial left, charged with his whole force of cavalry upon the Swedish right, but it stood against him firm as a rock. Here the king commanded in person, and repulsed seven successive charges of the impetuous Pappenheim, driving him at last from the field with broken and decimated ranks. In the meantime Tilly, having routed the small remnant of the Saxons, turned upon the left wing of the Swedes with the prestige of victory to animate his troops. This wing Gustavus, on seeing the repulse of his allies, had reinforced with three regiments, covering the flank left exposed by the flight of the Saxons. Gustav Horn commanded here, and met the attack with a spirited resistance, materially aided by the musketeers who were interspersed among the squadrons of horse. While the contest went on and the vigor of the attack was showing signs of weakening, King Gustavus, having put Pappenheim to rout, wheeled to the left and by a sharp attack captured the heights on which the enemy's artillery was planted. A short struggle gave him possession of the guns and soon Tilly's army was being rent with the fire of its own cannon. This flank attack by artillery, coming in aid of the furious onset of the Swedes, quickly threw the imperial ranks into confusion. Hitherto deemed invincible, Tilly's whole army broke into wild disorder, a quick retreat being its only hope. The only portion of it yet standing firm was a battalion of four veteran regiments, which had never yet fled the field and were determined never to do so. Closing their ranks, they forced their way by a fierce charge through the opposing army and gained a small thicket, where they held their own against the Swedes until night, when only six hundred of them remained. With the retreat of this brave remnant the battle was at an end, the remainder of Tilly's army being then in full flight, actively pursued by the Swedish cavalry, which kept close upon their tracks until the darkness of night spread over the field.
