The siege of Berat took place in July 1455 when the Albanian army of Skanderbeg attempted to capture the fortress in the Albanian city of Berat, which was held by Ottoman forces. The attempt resulted in a failure when an Ottoman relief army arrived and routed the besieging forces. Background When Skanderbeg began his rebellion, Berat belonged to the Albanian prince Theodore Muzaka. When in 1449 Theodore Muzaka was dying, he sent for Skanderbeg to take over the castle in the name of the League of Lezhë. Skanderbeg sent an Albanian detachment led by Pal Kuka, to claim the castle. In the meantime a force of Ottoman soldiers came from their garrison in Gjirokastër, quietly scaled the poorly guarded walls of Berat at night, slaughtered the Albanian garrison of about 500 soldiers, hanged the dying Theodore Muzaka, and claimed the castle, while the captain Pal Kuka was later ransomed. Berat was located on an important strategic position as it controlled much of southern Albania as well as the vital supply routes leading to southern Macedonia and Greece. Siege Skanderbeg and his forces besieged the Ottoman-occupied castle and began pounding it with the help of the Aragonese artillery. The commander of the Ottoman garrison then proposed to hand over the city if no reinforcements would come for a month. Believing the situation was well in hand and that the castle would fall, Skanderbeg left with a sizable contingent of his army in the direction of Vlorë. Although he tutored his commanders, Skanderbeg could never bring them up to his level of knowledge in military affairs. His formal training and experience in Anatolia and his service with the Ottoman army proved to be valuable for the Albanian resistance against the Ottomans. At the head of the remaining force he left Karl Muzaka Thopia, his brother-in-law, since Berat was formerly a possession of Muzaka's family. After a successful bombardment, the Ottoman commander of the garrison agreed to turn over the keys to the castle if the sultan had not sent reinforcements within a certain amount of time. This was a ploy to fool the Albanian forces into a false sense of security and delay any actions, giving reinforcements time to arrive. Battle The sultan sent an army of 20,000 troops led by Issa beg Evrenoz. The reinforcements surprised the Albanian army in mid-July, 1455. Only one Albanian commander, Vrana Konti (Kont Urani), managed
