After leaving a protective garrison of 1,500 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. By September the Ottoman camp was in disarray as morale sank and disease ran rampant. The Ottoman army acknowledged that the castle of Krujë would not fall by strength of arms, and lifted the siege and made their way to Edirne. Soon thereafter in the winter of 1450-1451, Murad died in Edirne and was succeeded by his son Mehmed II.
