Siege and capture of Tire
Consolidation of the Latin States of the East · Tire (today Sur, Lebanon)
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. Venetian Crusade 1122–1124; Tyre ceded to the Kingdom of Jerusalem (English Wikipedia).
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

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.
