Events

Spring – Bohemond I, Norman prince of Antioch, is released from Seljuk imprisonment at Niksar, after a ransom is paid of 100,000 gold pieces. During his absence, Tancred (Bohemond's nephew) attacks the Byzantines, and re-captures the cities of Tarsus, Adana and Mamistra in Cilicia. Tancred is deprived of his lordship by Bohemond's return, and is rewarded with a small fief within the Principality of Antioch.^[1]
The Crusaders under Raymond IV invade the Beqaa Valley and capture Tortosa to isolate Tripoli. Raymond expands towards the Orontes River, and begins to build a castle on the Mons Peregrinus which helps in the Siege of Tripoli (see 1102). Emperor Alexios I supports the Crusaders by sending a Byzantine fleet (ten ships) to blockade the port of Tripoli.^[2]
Summer – The Crusaders led by Bohemond I and Joscelin of Courtenay raid the territory of Aleppo to gain supplies. They capture the town of Muslimiyah, and extract a large tribute. Sultan Fakhr al-Mulk Radwan, the Seljuk ruler of Aleppo, agrees to pay 7,000 gold pieces and ten horses to the Crusaders while Bohemond agrees to release all Seljuk prisoners captured at Muslimiyah.^[3]
