According to these estimates, then, we may conclude that there were in the Imperial camp at Luetzen, on November 5th, from 15,000 to 18,000, or perhaps even 20,000, men. Such numbers offered to Gustavus, especially under the circumstances, a strong temptation to attack them; and, the Imperial army being so divided, he had a reasonable hope--a hope by which he was justified in forcing the engagement--that he should be able to defeat successively both divisions. Even as it was, Pappenheim's foot not arriving soon enough to support contributed in no small degree to the loss of the battle. The field, which was intersected by a canal that unites the Saale and the Elster, called the Flossgraben, was almost a level; but of all the accidents afforded by such ground Wallenstein had taken advantage. Luetzen lay to his right a little in front. Between it and three windmills close to his right wing intervened some mud-walled gardens. These he made use of as forts, throwing into them little garrisons, and loopholing the walls. The mill hills he converted into batteries, and the dry ditches by the roadside into breastworks for his musketeers. The fog having cleared off for a season, at ten o'clock the battle began. The wind and sun were in the King's favor; but Wallenstein had the advantage in weight of artillery and position. Gustavus did not long sustain the cannonade of the enemy before he gave the order to charge toward the highway and dislodge the musketeers who occupied the ditches on the side of it. This being effected, the whole line continued to advance, and the three infantry brigades of the centre took the batteries on the other side of the highroad, but, not being supported in time by their cavalry, who had been impeded by the wayside ditches, lost them again and were compelled to fall back. When the King knew that the first battery was taken, he uncovered his head and thanked God, but soon after, learning that the centre had been repulsed, he put himself at the head of the Smaland cavalry and charged the Imperial cuirassiers, the "black lads," with whom he had just before told Stalhaske to grapple. Piccolomini hastened to support the cuirassiers; and the Swedes, being overmatched, retreated without perceiving--the fog having again come over--that they had left the King in the midst of the enemy. A pistol-ball now broke his arm; and as the Duke of Lauenburg was supporting him out of the battle, an Imperial cuirassier came behind him and shot him in the back. He then fell from his horse; and, other cuirassiers coming up, one of them completed the work of death.
