Spaniards, uneasy even in Italy, were collecting their forces to make head against the irresistible conqueror, when the battle-field of Lutzen saw the fall, at thirty years of age, of the “hero of the North, the bulwark of Protestantism,” as he was called by his contemporaries, astounded at his greatness. God sometimes thus cuts off His noblest champions in order to make men see that He is master, and He alone accomplishes His great designs; but to them whom He deigns to thus employ He accords the glory of leaving their imprint upon the times they have gone through and the events to which they have contributed. Two years of victory in Germany at the head of Protestantism sufficed to make the name of Gustavus Adolphus illustrious forever. Richelieu had continued the work of Henry IV.; and Chancellor Oxenstiern did not leave to perish that of his master and friend. Scarcely was Gustavus Adolphus dead when Oxenstiern convoked at Erfurt the deputies from the Protestant towns, and made them swear the maintenance of the union. He afterwards summoned to Heilbronn all the Protestant princes; the four circles of Upper Germany (Franconia, Suabia, the Palatinate, and the Upper Rhine), and the elector of Brandenburg alone sent their representatives; but Richelieu had delegated M. de Feuquieres, who quietly brought his weight to bear on the decision of the assembly, and got Oxenstiern appointed to direct the Protestant party; the Elector of Saxony, who laid claim to this honor, was already leaning towards the treason which he was to consummate in the following year; France at the same time renewed her treaty with Sweden and Holland; the great general of the armies of the empire, Wallenstein, displeased with his master, was making secret advances to the cardinal and to Oxenstiern; wherever he did not appear in person the Imperial armies were beaten. The emperor was just having his eyes opened, when Wallenstein, summoning around him at Pilsen his generals and his lieutenants, made them take an oath of confederacy for the defence of his person and of the army, and, begging Bernard of Saxe-Weimar and the Saxon generals to join him in Bohemia, he wrote to Feuquieres to accept the king’s secret offers.
