The Egyptian campaign to occupy Syria began on October 29, 1831, starting the First Turko-Egyptian War. Two armies set out from Egypt, one by land under General Ibrahim Yakan, and the other by sea, landing at Jaffa, under Ibrahim Pasha. The Egyptians rapidly occupied Jerusalem and the coastal regions of Palestine and Lebanon, except for Acre, which had impregnable walls and a strong garrison of about 3,000 hardened fighters with much artillery. Acre, under the Ottoman Paha Abdullah Elgazar, held out against a long and bloody siege before finally falling to the Egyptians on May 27, 1832.
