This last result was not effected till a long time after Mehlen had been deposed. Before leaving Kalmar he had intrusted matters to his brother, with orders not to yield the castle to any but himself. As soon, therefore, as the new officer approached to take his fief, the reply was given him that the castle would not be yielded till Mehlen should return. After some three weeks spent in futile negotiation, Gustavus wrung from Mehlen a letter directed to his brother, instructing him to yield. This the monarch sent to Kalmar, April 8, along with a letter of his own. Convinced that the whole delay on the part of Mehlen was to use up time, he instructed his messenger to warn the occupants that if the castle were not surrendered by the 1st of May, he would make them smart for it. In his letter, however, Gustavus used more gentle language. "We have kept your brother here," he wrote, "in order to protect him from the populace, whose mouths are full of scandal about our relations to him. From your letter it appears you thought we held him in confinement.... We are minded to treat him well and kindly, unless we shall be forced by you to treat him otherwise. We warn you, however, we shall deal with Kalmar in the way that we deem best, for the town and castle belong to God, to us, and to the Swedish crown.... Our counsel is that you obey our mandate, and the earlier you do so the better it will be for you." Accompanying this letter was a passport, similar to one drawn up for Mehlen, to take his brother from the realm. He was not, however, to be allured by passports or even terrified by threats. The castle continued firm, and Gustavus began to levy forces to besiege it.[116]
