ALBRECHT VON WALLENSTEIN 197 The rich city of Magdeburg declared for him, and was accordingly besieged by Tilly. The selfishness of the Lutheran leaders, the Electors of Brandenburg and Saxony, in not responding to the appeal of the Protestants in the city; led to its fall in 1631, before Gustavus could reach it. The most atrocious cruelties were perpetrated by the Catholics at the sack ; no consideration of age or sex availing to prevent the massacre, which lasted for two days, and extended to 30,000 of the inhabitants. This monstrous crime was severely avenged by the indignant Gus- tavus. He forced the Electors of Brandenburg and Saxony to render him assist- ance, and, with an augmented army, hesitated not to give battle to Tilly at Leip- sic, and defeated him September 7, 1631. The Protestants took courage and joined Gustavus in great numbers. He continued his victorious march, defeat- ing the enemy at Merseberg, capturing Wurzburg, then advancing on the Rhine, and reducing on the way Frankfort-on-the-Main, Mentz, Spires, Mannheim, and other cities. He next turned to Bavaria, where Tilly and Maximilian entrenched themselves at Rain-on-the-Lech. The former was killed by a cannon-ball during the siege, in 1632. Gustavus marched through Augsburg, where the citizens did him homage, and besieged Munich, which speedily surrendered. He now threatened to subdue Bavaria and Austria, when his progress was stopped from an unexpected quarter. 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 move- ments 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
