Vrana had returned to Albania in the years prior to the beginning of the Albanian-Turkish wars under the leadership of Gjergj Kastrioti Skanderbeg in 1443. Vrana was one of his closest and most trusted allies. He may be the
Urana who is mentioned in a document of Ottoman
Krujë in relation to events as a result of which Skanderbeg was given direct control of the village of
Mamurras. Christian volunteers from all over Europe had arrived in Krujë to assist the defense against the upcoming Ottoman siege - Slavs, Italians, Germans and others. Skanderbeg left a protective garrison of 1,500 to 4,000 under Vrana in the town, while he harassed the Ottoman camps around Krujë by continuously attacking Sultan Murad II's supply caravans from Mount Tumenishta. Vrana had under his command several
Germans,
Italians, and
Frenchmen, to whom he emphasized the importance of the siege and also ordered them to their positions. Krujë had enough supplies for a sixteen-month siege. The women and children of Krujë were sent for protection to
Venetian possessed areas, whereas the others were ordered to burn their crops and move into the mountains and fortresses. Vrana's stance in the siege of Krujë is remembered in many folk songs and their variants in the region that Skanderbeg held. Vrana was one of the commanders in the
Siege of Berat in 1455. The purpose of the siege was to recover the city of
Berat for the
Muzaka family and establish a firm stronghold for the
League of Lezhë in southern Albania. Skanderbeg's army had 15,000 men including a 1,000 man strong Neapolitan contingent of siege warfare engineers which Alfonso had sent to deal with the fortification of the
Berat Castle. The siege was at first successful and the fortifications were breached. An armistice was signed and the Albanian army expected that the Ottomans would surrender. Skanderbeg moved with a contingent to another area. In mid July, however, the Ottomans sent an army of 20,000 troops led by
Evrenosoglu Isa Bey, which surprised Skanderbeg's army. Only one commander, Vrana, managed to resist the initial Ottoman onslaught and pushed back several attacking waves. His efforts were not able to change the course of the battle and the Ottoman army won. More than 5,000 of Skanderbeg's men died, including 800 men of the 1,000 Neapolitans. The commander of the siege, Muzaka Thopia, was also killed during the conflict. Vrana died in 1458. He died in the same year as
Alfonso the Magnanimous and
Pope Callixtus III who died on June 27 and on August 6, 1458 respectively. His death was a major blow to Skanderbeg who in a short period lost his most trusted commander Vrana and his most important political allies. In the folklore of the Albanians of
Upper Reka, Vrana is buried in that region with possible locations given near the village of
Rimnica. In one of the variants of the story, when he returned to the village he was sick and disappointed by the possible outcome of the war. He climbed Skerteci, a mountain near
Tanusha and gathered two large stone slabs which he told the villagers to use to make his tombstone. == Historiography and literature ==
