Tilly's usual intrepidity and resolution seemed to forsake him on this eventful day. He had formed no regular plan for giving battle to the King, and he displayed as little firmness in avoiding it. Contrary to his own judgment, Pappenheim had forced him to action. Doubts which he had never before felt, struggled in his bosom; gloomy forebodings clouded his ever-open brow; the shade of Magdeburg seemed to hover over him. A cannonade of two hours commenced the battle; the wind, which was from the west, blew thick clouds of smoke and dust from the newly-ploughed and parched fields into the faces of the Swedes. This compelled the king insensibly to wheel northwards, and the rapidity with which this movement was executed left no time to the enemy to prevent it. Tilly at last left his heights, and began the first attack upon the Swedes; but to avoid their hot fire, he filed off towards the right, and fell upon the Saxons with such impetuosity that their line was broken, and the whole army thrown into confusion. The Elector himself retired to Eilenburg, though a few regiments still maintained their ground upon the field, and by a bold stand saved the honour of Saxony. Scarcely had the confusion began ere the Croats commenced plundering, and messengers were despatched to Munich and Vienna with the news of the victory. Pappenheim had thrown himself with the whole force of his cavalry upon the right wing of the Swedes, but without being able to make it waver. The king commanded here in person, and under him General Banner. Seven times did Pappenheim renew the attack, and seven times was he repulsed. He fled at last with great loss, and abandoned the field to his conqueror. In the mean time, Tilly, having routed the remainder of the Saxons, attacked with his victorious troops the left wing of the Swedes. To this wing the king, as soon as he perceived that the Saxons were thrown into disorder, had, with a ready foresight, detached a reinforcement of three regiments to cover its flank, which the flight of the Saxons had left exposed. Gustavus Horn, who commanded here, showed the enemy's cuirassiers a spirited resistance, which the infantry, interspersed among the squadrons of horse, materially assisted. The enemy were already beginning to relax the vigour of their attack, when Gustavus Adolphus appeared to terminate the contest. The left wing of the Imperialists had been routed; and the king's division, having no longer any enemy to oppose, could now turn their arms wherever it would be to the most advantage. Wheeling, therefore, with his right wing and main body to the left, he attacked the heights on which the enemy's artillery was planted. Gaining possession of them in a short time, he turned upon the enemy the full fire of their own cannon.
