Hunyadi invaded Wallachia and dethroned Vlad Dracul in December 1447. According to the contemporaneous Polish chronicler Jan Długosz, Hunyadi had "the very man he promised to make voivode" blinded, and planned "to appropriate" Wallachia for himself. Hunyadi styled himself "voivode of the Transalpine land" and referred to the Wallachian town, Târgoviște as "our fortress" in a letter of 4 December. It is without doubt that Hunyadi installed a new voivode in Wallachia, but modern historians debate whether the new voivode was Vladislav II (to whom Hunyadi referred as his relative in a letter) or Dan (who seems to have been a son of Basarab II). In February 1448 Hunyadi sent an army to Moldavia to support the pretender Peter in seizing the throne. In exchange, Peter acknowledged Hunyadi's suzerainty and contributed to the installation of a Hungarian garrison in the fort of Chilia Veche on the Lower Danube.
