The emperor, justly mistrusting the loyalty of Maximilian, who was in league with France, now saw himself deprived of his ablest generals, and felt his power failing. He turned to Wallenstein as the only man who could save the Empire. That leader was meantime living in retirement, and secretly glad of the success of Gustavus. He refused at first to take the command of the imperial army, and only consented at last on condition of having sole and absolute authority, with the right of disposing as he pleased of his conquests. These humiliating terms were accepted by Ferdinand, and in a few months after the death of Tilly, Wallenstein was in the field with a large and powerful army, raised, as before, by his own exertions. He drove the Saxons from Bohemia, and thence marched to Leipsic, which capitulated. At Nuremberg, where Gustavus offered him battle, he wisely refused, and for three months the two camps remained close to each other, each general trying to exhaust the patience of his adversary, and relying on the destructive effects of famine and pestilence. Gustavus was forced to withdraw, after losing 20,000 men; a yet heavier loss, nevertheless, having befallen Wallenstein, whose numbers were better able to bear it. Gustavus marched southward, but soon returned to attack Wallenstein, who had moved northward, and was pillaging the neighborhood of Leipsic. The two armies met at Lutzen on November 6, 1632. A dense fog shrouded the movements of each side from the other, and created a fearful confusion. Wallenstein ranged his infantry in squares, having a ditch in front, and flanked by his cavalry. Gustavus headed his men and charged the enemy across the ditch. But his own infantry was borne down by the black cuirassiers of Wallenstein, and, as he turned to attack them, the thick fog concealed their approach. His horse was wounded, and he himself had his arm broken. In moving off the field he was shot in the back, and falling from his saddle was dragged in the stirrup. He fell into the hands of the cuirassiers, one of whom, as the Swedes came up to the succor of their king, shot him through the head. His corpse was discovered after the battle, and honorably buried. The death of their king caused the deepest affliction to the Swedes, but aroused instead of enfeebling their courage. A charge of the Duke of Weimar, one of the Protestant leaders, threw Wallenstein's infantry and cavalry into disorder. An attempt of the Imperialist General Pappenheim, who now came up with a reserve to retrieve the battle, was for a time successful. But as the tide of fortune seemed turning against the Swedes, a reserve of their own army made a last desperate charge, carried the ditch which protected Wallenstein's infantry, and won the day; the Imperialists fleeing in all directions and their great leader escaping into Bohemia.
