Nur al-Din asked for and received a safe-conduct from Baldwin III of Jerusalem for Usama b. Munqidh's wives and children to join him from Egypt. They left Egypt on a Frankish ship, but as they were approaching Acre they were assaulted and their possessions stolen by Franks (including money, jewelry and a huge library). The raid was ordered by Baldwin III in person. A member of Usama's retinue swam to shore and showed the king the safe-conduct with his own authorisation, but he refused to stop the robbery. He told the man that this was the way with Muslims. Fortunately they were set free, but with only 500 dinars for the whole party
