His operations were far-ranging and his restless activity dominated the country from Stade to Kassel, and from Hildesheim to Maastricht. Being now a field marshal in the imperial service, he was recalled to join Wallenstein, and assisted the generalissimo in Saxony against the Swedes; but, was again despatched towards Cologne and the lower Rhine. In his absence a great battle became imminent, and Pappenheim was hurriedly recalled. He appeared with his horsemen in the midst of the battle of Lützen (16 November 1632). His furious attack was for the moment successful. As Rupert at Marston Moor sought Cromwell as his worthiest opponent, so now Pappenheim sought Gustavus. At about the same time as the king was killed, Pappenheim received a mortal wound in another part of the field. He died later the same day or early the next morning en route to Leipzig, where his body was embalmed at the Pleissenburg fortress.
