Encouraged by the Christian success, Ivan Shishman immediately invalidated his vassalage to Murad I and refused to send troops in his support in 1388.
The Ottomans reacted by sending a 30,000-strong army under the command of the grand vizier Ali Pasha, to the north of the Balkan Mountains, which invaded the Tarnovo Tzardom.
After the majority of the Turkish troops left the Despotate, the Voevode of Wallachia, Mircea I, defeated the Turks and entered Silistra.
