 When Frederick Adolf continued to be in love with Sophie von Fersen after two years had passed, him and his brother Duke Charles proposed to Sophie von Fersen that they would abduct her from a ball of the duchess Charlotte and bring her to Prince Frederick's residence Tullgarn Palace, where a priest would be waiting to perform the ceremony before it could be prevented.Sophie declined the offer after having consulted duchess Charlotte, mostly, as it seemed, out of pride.She informed Frederick Adolf of her decision at a masquerade ball in the presence of duchess Charlotte.
