Georg Wilhelm, Elector of Brandenburg (1595-1640). Letter m. U. "E. Ld. ==References====External links==* Official website 2 pp. Folio. Fortress Peitz 22.X.1636. In the middle of the Thirty Years' War to the (unnamed) Margrave Christian von Brandenburg-Bayreuth (1581-1655), who had written to him that his son, Erdmann's heir prince, would like to go to the Brandenburg court in August (1615-1651). Georg Wilhelm refuses the wish on the grounds that the Berliner Hof had to flee to the fortress Peitz, because the imperial and Kursächsische army allied with Brandenburg "after held Bataille" withdrew to the winter quarter near Halberstadt and Brandenburg, with the exception of the fortress Landsberg a. d. Warthe, is now almost entirely in Swedish hands. In the fortress Peitz it is too narrow for the prince to "accomodiren" himself with his and the Brandenburg court state there. - Interesting situation picture from the 30-year-old war.
