After the capture of Antioch (June 1098) and the destruction of Ma'arrat al-Numan (January 13, 1099), the Syrian emirs were terrified of the advancing crusaders and quickly handed over their cities to the Franks. On January 14, Sultan ibn Munqidh, emir of Shaizar, dispatched an embassy to Raymond IV of Toulouse, one of the leaders of the crusade, to offer provisions and food for men and horses, as well as guides to Jerusalem. In February, the emir of Homs, Janah ad-Dawla, who had fought bravely at the siege of Antioch, offered horses to Raymond. The qadi of Tripoli, Jalal al-Mulk, from the Banu Ammar, sent rich gifts and invited the Franks to send an embassy to his city. The ambassadors marvelled at the splendors of the city, and an alliance was concluded. The crusades moved on to Arqa, which they besieged from February 14 to May 13, before continuing south to Jerusalem; they did not attack Tripoli or any other possessions of the Banu Ammar.
