ティルジットの和約
Werther was the son of Generalleutnant (Lieutenant General) Von Werther. He himself also joined the Prussian military in 1787. He participated in the War of the Fourth Coalition as a Rittmeister in the Dragoon regiment of his father, who had died in 1802. After the Treaties of Tilsit, Werther left the army as a Captain due to a reduction in size of the armed forces. For a while, he then became a chamberlain to Friedrich Wilhelm III.
