The joined forces of Manuel and Amalric laid siege to [[Damietta]] on 27 October 1169, but the siege was unsuccessful due to the failure of the Crusaders and the Byzantines to co-operate fully.<ref name="R84-86">R. Rogers, ''Latin Siege Warfare in the Twelfth Century'', 84–86</ref> According to Byzantine forces, Amalric, not wanting to share the profits of victory, dragged out the operation until the emperor's men ran short of provisions and were particularly affected by famine; Amalric then launched an assault, which he promptly aborted by negotiating a truce with the defenders. On the other hand, William of Tyre remarked that the Greeks were not entirely blameless.<ref>William of Tyre, ''Historia'', XX [http://thelatinlibrary.com/williamtyre/20.html#15 15–17]</ref> Whatever the truth of the allegations of both sides, when the rains came, both the Latin army and the Byzantine fleet returned home, although half of the Byzantine fleet was lost in a sudden storm.<ref name="TM68">T.

Despite the bad feelings generated at Damietta, Amalric still refused to abandon his dream of conquering Egypt, and he continued to seek good relations with the Byzantines in the hopes of another joined attack, which never took place.<ref name="TM68-69">T. F. Madden, ''The New Concise History of the Crusades'', 68–69</ref> In 1171 Amalric came to Constantinople in person, after Egypt had fallen to [[Saladin]]. Manuel was thus able to organise a grand ceremonial reception which both honoured Amalric and underlined his dependence: for the rest of Amalric's reign, Jerusalem was a Byzantine satellite, and Manuel was able to act as a protector of the Holy Places, exerting a growing influence in the Kingdom of Jerusalem.<ref name="MM75">P.

Mayer, ''The Latin East'', 657</ref> In 1177, a fleet of 150 ships was sent by Manuel I to invade Egypt, but returned home after appearing off Acre due to the refusal of Count [[Philip I, Count of Flanders|Philip of Flanders]] and many important nobles of the [[Kingdom of Jerusalem]] to help.<ref>J.
