Siege of Sidon (1110)
Also known as Crusader capture of Sidon

From 19 October to 5 December 1110, Baldwin I besieged the Fatimid-held coastal city of Sidon with the assistance of the Doge of Venice Ordelafo Faliero and a Norwegian fleet of sixty ships under King Sigurd I, who had taken the cross and travelled by sea via Spain and Sicily to fight in the Holy Land. The combined land-and-sea operation cut the city off completely; the garrison surrendered on terms in early December. The capture of Sidon established the Lordship of Sidon as one of the great fiefs of the kingdom and removed another link in the chain of Fatimid ports along the Levantine coast.
