[Illustration: Gustavus Adolphus----282] “The King of Sweden was a new rising sun, who, having been at war with all his neighbors, had wrested from them several provinces; he was young, but of great reputation, and already incensed against the emperor, not so much on account of any real injuries he had received from him as because he was his neighbor. His Majesty had kept an eye upon him with a view of attempting to make use of him in order to draw off, in course of time, the main body of the emperor’s forces, and give him work to do in his own dominions.” [_Memoires de Richelieu,_ t. v. p. 119.] Through Richelieu’s good offices, Gustavus Adolphus had just concluded a long truce with the Poles, with whom he had been for some time at war: the cardinal’s envoy, M. de Charnace, at once made certain propositions to the King of Sweden, promising the aid of France if he would take up the cause of the German princes; but Gustavus turned a cold ear to these overtures, “not seeing in any quarter any great encouragement to undertake the war, either in England, peace with the Spaniards being there as good as determined upon, or in Holland, for the same reason, or in the Hanseatic towns, which were all exhausted of wealth, or in Denmark, which had lost heart and was daily disarming, or in France, whence he got not a word on which he could place certain reliance.” The emperor, on his side, was seeking to make peace with Sweden, “and the people of that country were not disinclined to listen to him.” God, for the accomplishment of his will, sets at nought the designs and intentions of men. Gustavus Adolphus was the instrument chosen by Providence to finish the work of Henry IV. and Richelieu. Negotiations continued to be carried on between the two parties, but, before his alliance with France was concluded, the King of Sweden, taking a sudden resolution, set out for Germany, on the 30th of May, 1630, with fifteen thousand men, “having told Charnace that he would not continue the war beyond that year, if he did not agree upon terms of treaty with the king; so much does passion blind us,” adds the cardinal, “that he thought it to be in his power to put an end to so great a war as that, just as it had been in his power to commence it.”
