* Summer – King Henry I ("the Fat") sends a Cypriot squadron of 8 galleys with 100 knights led by Baldwin of Ibelin, to Acre. With the support of the Italian colonists, they fitted out 7 more galleys and some 50 lighter ships, to relieve the siege at Ascalon – which is now blockaded by the Egyptian fleet.
* The Egyptian fleet (some 20 galleys) confronts the Crusader ships led by Baldwin of Ibelin at Ascalon. But before contact is made, it is caught in a sudden Mediterranean storm. Many of the Muslim ships are driven ashore and wrecked; the survivors sail back to Egypt.
