In 1732, Frederick was restored to the Prussian Army as Colonel of the Regiment von der Goltz, stationed near Nauen and Neuruppin. When Prussia provided a contingent of troops to aid the Army of the Holy Roman Empire during the War of the Polish Succession, Frederick studied under Reichsgeneralfeldmarschall Prince Eugene of Savoy during the campaign against France on the Rhine; he noted the weakness of the Imperial Army under the command of the Archduchy of Austria, something that he would capitalize on at Austria's expense when he later took the throne. Frederick William, weakened by gout brought about by the campaign and seeking to reconcile with his heir, granted Frederick Schloss Rheinsberg in Rheinsberg, north of Neuruppin. At Rheinsberg, Frederick assembled a small number of musicians, actors and other artists. He spent his time reading, watching and acting in dramatic plays, as well as composing and playing music. Frederick formed the Bayard Order to discuss warfare with his friends; Heinrich August de la Motte Fouqué was made the grand master of the gatherings. Later, he regarded this time as one of the happiest of his life.
