In this city, a number of princes and ambassadors were assembled to congratulate Gustavus on his success, and either to conciliate his favour or to appease his indignation. Among them was the fugitive King of Bohemia, the Palatine Frederick V., who had hastened from Holland to throw himself into the arms of his avenger and protector. Gustavus gave him the unprofitable honour of greeting him as a crowned head, and endeavoured, by a respectful sympathy, to soften his sense of his misfortunes. But great as the advantages were, which Frederick had promised himself from the power and good fortune of his protector; and high as were the expectations he had built on his justice and magnanimity, the chance of this unfortunate prince's reinstatement in his kingdom was as distant as ever. The inactivity and contradictory politics of the English court had abated the zeal of Gustavus Adolphus, and an irritability which he could not always repress, made him on this occasion forget the glorious vocation of protector of the oppressed, in which, on his invasion of Germany, he had so loudly announced himself. The terrors of the king's irresistible strength, and the near prospect of his vengeance, had also compelled George, Landgrave of Hesse Darmstadt, to a timely submission. His connection with the Emperor, and his indifference to the Protestant cause, were no secret to the king, but he was satisfied with laughing at so impotent an enemy. As the Landgrave knew his own strength and the political situation of Germany so little, as to offer himself as mediator between the contending parties, Gustavus used jestingly to call him the peacemaker. He was frequently heard to say, when at play he was winning from the Landgrave, "that the money afforded double satisfaction, as it was Imperial coin." To his affinity with the Elector of Saxony, whom Gustavus had cause to treat with forbearance, the Landgrave was indebted for the favourable terms he obtained from the king, who contented himself with the surrender of his fortress of Russelheim, and his promise of observing a strict neutrality during the war. The Counts of Westerwald and Wetteran also visited the King in Frankfort, to offer him their assistance against the Spaniards, and to conclude an alliance, which was afterwards of great service to him. The town of Frankfort itself had reason to rejoice at the presence of this monarch, who took their commerce under his protection, and by the most effectual measures restored the fairs, which had been greatly interrupted by the war.
