The elector of Brandenburg still vacillating, the king of Sweden was as good as his word, and advanced with his army, with loaded cannon and matches burning, to the gates of Berlin. Whereupon, the treaty of alliance was quickly signed by the elector of Brandenburg; and not long after, the outrages of the imperial commander obliged the elector of Saxony also to join the Swedish king. During the first year in Germany, the Swedes had captured Greiffenhagen and Gartz; and soon after New Brandenburg, Loitz, Malchin, and Demmin were in their power. We have no space to note the particulars regarding these important conquests, and can only mention the taking of Demmin. The Imperialists had placed the garrison here under the command of Duke Savelli, who had been ordered to defend the place three weeks, when Tilly had promised to come to his aid. Among the Imperialists was Del Ponte, a man who had been deep in a conspiracy to assassinate the king of Sweden, which had come near being successful. As Del Ponte feared the vengeance of the king whose life he had thus sought, he left the fortress secretly, leaving his baggage and wealth behind him. Savelli offered to capitulate, on condition that he might pass out with arms and baggage. As Gustavus was now on the eve of meeting Tilly, he did not think best to prolong the siege, and so agreed to the proposal of Savelli. The entire garrison passed out with ensigns flying, followed by the baggage train. As Savelli, brilliantly and carefully dressed, passed the Swedish king, Gustavus addressed him: “Tell the emperor I make war for civil and religious liberty. As to you, duke, I thank you for having taken the trouble to quit the splendid feasts of Rome to combat against me, for your person seems to me more in its place at courts than in the camps.” After the Italian general passed, Gustavus remarked to his officers, “That man reckons much on the good nature of the emperor; if he was in my service, he would lose his head for his cowardice.”
