Possibly the hope on the Baden side was that Karl III August would decide on the portion in which Birkenfeld and the family seat were located; nonetheless, Karl III August decided upon the Mosel region around Trarbach, so that after 1776 the Birkenfeld region became the exclusive possession of Baden.
Badeni poole lootus oli arvatavasti, et Karl III August otsustab valida osa, kus paiknesid Birkenfeld ja perekonna kodu; sellest hoolimata otsustas Karl III August valida Moseli piirkonna ümber Trarbachi, nii et pärast 1776. aastat sai Birkenfeldi piirkond Badeni ainuomanduseks.
