 The Christians delayed three days in attacking the city, allowing Saladin to hastily move in troops and supplies.The siege was prosecuted with vigour on both sides, with Kontostephanos and his men constructing huge siege towers, but the besiegers were hampered by the growing mistrust between Byzantines and Crusaders, especially as the Byzantines' supplies dwindled, and Amalric refused to share his own with them but sold them at exorbitant prices.Exasperated by the dragging-on of the siege and the suffering of his troops, Kontostephanos once again disobeyed Manuel's instructions ordering him to obey Amalric in all things, and launched with his troops a final attack on the city.
