The battle of Lutzen was fought on the 16th of November, 1632. It is generally estimated that the imperial troops were forty thousand, while there were but twenty-seven thousand in the Swedish army. Gustavus was then thirty-eight years of age. A plain stone still marks the spot where he fell. A few poplars surround it, and it has become a shrine visited by strangers from all parts of the world. Traces of his blood are still shown in the town-house of Lutzen, where his body was transported from the fatal field. The buff waistcoat he wore in the engagement, pierced by the bullet which took his life, is preserved as a trophy in the arsenal at Vienna. Both as a monarch and a man, this illustrious sovereign stands in the highest ranks. He possessed the peculiar power of winning the ardent attachment of all who approached him. Every soldier in the army was devoted to him, for he shared all their toils and perils. "Cities," he said, "are not taken by keeping in tents; as scholars, in the absence of the master, shut their books, so my troops, without my presence, would slacken their blows." In very many traits of character he resembled Napoleon, combining in his genius the highest attributes of the statesman and the soldier. Like Napoleon he was a predestinarian, believing himself the child of Providence, raised for the accomplishment of great purposes, and that the decrees of his destiny no foresight could thwart. When urged to spare his person in the peril of battle, he replied, "My hour is written in heaven, and can not be reversed."
