For a full month the Hungarians were encamped there awaiting the German crusaders, the Wallachian Duke as well as the Bohemian and Albanian army.[4] The Albanian army under Skanderbeg did not participate in this battle as he was prevented from linking with Hunyadi's army by the Ottomans and their allies.[4][5] It is believed that he was delayed by Serbian despot Đurađ Branković, then allied with Sultan Murad II, although Branković's exact role is disputed.[6][7][8] As a result, Skanderbeg ravaged Branković's domains as punishment for deserting the Christian cause.[5][9]
