After a few days in detention, Dracul was released on three conditions imposed by the Turkish court, including the condition of leaving two sons hostage for an indefinite period. Although hesitated, Dracul still agreed. Dracula and Radu were taken from Gallipoli to Adrianople, the central city of Turkey, not treated like prisoners but under constant surveillance.

In 1445, once again, the “White Knights” wanted to make an expedition against the Ottomans. This time, Dracul did not want to be criticized for not participating, so he sent his eldest son Mircea to head the 4,000 cavalry. He also refused to directly hold the weapon, fearing that Murad II would harm his two sons held hostage.
