Wallenstein was making for Saxony because it was the richest portion of the country, and he really hoped Maximilian would be humiliated by a defeat. General Arnin commanded the army of Saxony, which numbered about twenty thousand men. Much of the fluctuating conduct of the Elector must be placed to the discredit of this Catholic adviser whose heart was always with the emperor and not with his king and country. Oxenstiern came up on the west bank of the river, and in Alsace had possessed himself of Strasburg, then a free imperial city. He also drove the Spaniards and Lorainers before him, and they were this time, for the most part, driven from German soil. Pappenheim and Tott were keeping each other occupied on the Weser, so that neither could help the main army to which he belonged, but the Swedes had the Archbishopric of Bremen, and Gustavus felt that it was necessary to win one great battle on account of all that floating element which shouts only with the winner. They must be again brought to shout for the Protestant side. Wallenstein attacked Schweinfurt after losing Maximilian's division. Bernard rushed to the defence of the city, and Wallenstein, having double the number of soldiers, retired. Then Bernard protected the passes through the Thuringian forests, and kept the way open for Gustavus and the main body of the Protestant army to make its way to Erfurth. Pappenheim was almost if not altogether as ruthless as Wallenstein, but morally a better man. The latter kept ordering the former to join him, but Pappenheim had so long been in independent command that he hated to do this. For one thing, the stealings would have to be reported, and, for another, General Tott would harass the rear of his army, but at length a junction of the two armies was made a few days before Gustavus entered Saxony, which was October 21st. Wallenstein, as a sort of warning of the coming scourge, sent Colonel Hölch with the most savage of the Croats into Saxony, and while he wrote hypocritical letters to the effect that the peasantry should not be molested, yet the robbers knew they were to leave nothing behind them.
