The League of Lezhë, led by Skanderbeg, experienced low morale after losing Svetigrad and Berat between 1448 and 1450. Nevertheless, Skanderbeg's exhortations and the support of the clergy, who claimed to have had visions of angels and victory, motivated the Albanians to defend the capital of the League, Krujë, at all costs. After leaving a protective garrison of 4,000 men under his trusted lieutenant Vrana Konti (also known as Kont Urani), Skanderbeg harassed the Ottoman camps around Krujë and attacked the supply caravans of Sultan Murad II's army.
