[9] After having been appointed Beglerbeg of Bosnia, Telli Hasan Pasha had the Rmanj Monastery renewed as a seat of his brother, Serbian Orthodox monk Gavrilo Predojević.

A bellicose and dynamic military leader,[12] Hasan strengthened the army of the Eyalet equipping it with better horses and erecting a bridge at Gradiška with the purpose of easier maneuvering between Bosnia and Slavonia.

[17] After learning this, Hasan Pasha felt himself encouraged enough to lead his forces towards Bihać,[18] which was conquered on 19 June 1592[19] after eight days of siege,[20] along with several surrounding forts.

[9] Records show that nearly 2,000 people died in defense of the town, and an estimated 800 children were taken for Ottoman servitude (see devshirme), to be educated in Islam and become janissaries, as Hasan had been himself.

After having placed a sufficient garrison in Bihać, he erected two other fortresses in its vicinity; the command of which he conferred to Rustem-beg, who was the leader of the Grand Vizier Ferhad Pasha's militia.

[21] In all, during this two-year campaign, the Ottoman Bosnian regional invading forces, led by Hasan Pasha, burned to the ground 26 cities throughout the Croatian Frontier and took some 35,000 war captives.
