Fifty-two warships from Pisa arrive at Tyre to aid in the city's defense. In 1124 Crusaders starved Muslim Tyre into submission with the aid of a Venetian sea blockade and it has become one of the most important cities in the Crusaders' Latin Kingdom of Jerusalem.
Saladin is ultimately in command of the Muslim forces besieging Tyre and he is also responsible for the city's ability to withstand the siege. Not only has Tyre's defenses been improved, but it is filled with refugees and soldiers whom Saladin had allowed to go free from other cities he has captured in the region. This means that Tyre is filled with eager Christian Crusaders, all under the command of Conrad of Montferrat.
It will be over 100 years before Muslim take control of Tyre again.
