When Krujë was besieged by the Ottomans, the sixty-seven-year-old Gjergj Arianiti joined the battle and fought fiercely. Along with 3,000 warriors, he joined the anti-Venetian force which eventually defeated the Venetian army at Drin. He was one of the main commanders during the short siege of Durrës and the siege of Dagno. Some of his troops went as far as the gates of Shkodër. Thus, his interests were not harmed by Venice, who wished to incorporate the bay of Vlorë into its dominions.
