The annexation of Saxe-Eisenach was favorable to the hunt-loving duke; he possessed a large swath of woods in the Eisenach region, which seemed suitable to him for hunting. He left the Hereditary Prince in Weimar in the Schloss Belvedere, under the guardianship of his Hofmarschall, and moved permanently to Eisenach. After this, the duke rarely asked for his son, and sent the most unreasonable written instructions from Eisenach to Weimar in order to supervise his son's education. The Hereditary Prince saw his father for the last time in 1743.
