The marriage was celebrated in Baden on 2 June of that year, but Gerhard VII quickly returned to his domains in order to secure his frontiers without an official wedding night.
To stop the increased rumours about his paternity, in February Gerhard VII declared in the courtyard of Gottorf Castle in front of his knights that he secretly slept with Agnes before the wedding, and that she'd been a virgin then; therefore, the children were his, and Henry would be capable of inheriting his possessions.
Against medical advice, Agnes and her husband travelled to a spa in her native Baden; however, in the middle of the trip, Gerhard VII became worse and in Cologne they decided to return.
During her return in Hamburg, Agnes received unexpected news: her brother-in-law Adolphus VIII refused her entry to Holstein, kidnapped her children and denied her rights as a widow, because her dowry was never paid and the recent scandal about the paternity of the twins.
Her brother Margrave Jacob of Baden at first strongly supported her rights; however, on 2 June 1436 she was secretly betrothed and married with Hans von Höwen, a former admirer.
