Siege and capture of Tire
Summary
From November 1123 to July 1124, Baldwin II, supported by the Venetian fleet of doge Domenico Michiel and by contingents from France, besieged Tyre, the last major Fatimid port on the coast. The Latins built giant towers, relentlessly bombarded the ramparts and suffocated the city with a complete maritime blockade. Exhausted by famine, the garrison capitulated on July 7, 1124.
Historical context
After the capture of Sidon and Beirut, the Kingdom of Jerusalem wanted to secure the entire coastline to guarantee communications with the West. The Pactum Warmundi signed with Venice in 1123 ensures the sending of an imposing fleet in exchange for commercial privileges. Lords from Provence, Champagne and Normandy responded to the pontifical call to complete the conquest of the Levantine ports.
Tactics
The siege combined a tight naval blockade – Venetian galleys closing the outer port with chains and fireships – and land engineering operations: rolling towers, undermining the foundations, catapults pounding the northern wall. The Fatimid sorties were repulsed by the Provençal knights, while the fleet prevented any resupply, forcing the surrender.
Consequences
The fall of Tire completes the chain of free ports between Ascalon and Antioch, guaranteeing a continuous supply of men and goods from France and Italy. Venice obtains a large autonomous district and tax exemptions, making Tire a center of Mediterranean trade. Customs revenues allowed Baudouin II to finance garrisons and fortifications.
