Abdullah sought intervention on his behalf by Muhammad Ali, who had been supporting the Ottomans against Greek rebels in Morea. Darwish Pasha, sought to gain actual control of Sidon Eyalet before Abdullah and Emir Bashir could regroup, and besieged Acre in July 1822. Mustafa Pasha and Bahram Pasha backed the siege with their forces. Abdullah's forces numbered around 2,000, consisting of his personal guard, a number of professional soldiers, and Arab and Turkish irregulars. The siege was supported financially by Salamun Farhi of Damascus, who was present in Darwish Pasha's camp outside of Acre. After five months of no tangible results from the siege, Darwish Pasha was dismissed from the governorship of Sidon and replaced by Mustafa Pasha.
