A defeat of the army of Baldwin I of Jerusalem by a Turkish coalition led by Mawdûd, atabeg of Mosul, and Tughtigīn, atabeg of Damascus, who had launched a joint attack on the kingdom of Jerusalem at the instigation of the Saljûq sultan Muhammad.
The combined Turkish armies invaded Galilee in late May 1113, whereupon Baldwin I summoned assistance from the principality of Antioch and the county of Tripoli, but without waiting for reinforcements to arrive, moved against the invasion with some 700 knights and 4,000 foot soldiers. Near the village of al-Sinnabrāh, south of Lake Tiberias, the Franks were lured into an ambush in which they suffered heavy casualties and then retreated to a hilltop position west of Tiberias (mod. Teverya, Israel) on 28 June 1113. Although joined there by contingents under Prince Roger of Antioch and Count Pons of Tripoli, Baldwin did not dare attack, and for the next two months much of the countryside of the kingdom was under the effective control of the Turks, who ravaged as far as Jaffa (mod. Tel Aviv-Yafo, Israel) and Jerusalem, finally withdrawing at the end of August, when the Frankish forces had been swelled by large numbers of pilgrims.
