After Yarankash, a Frankish slave, assassinated Zengi in September 1146, Joscelin II recaptured Edessa in October 1146. Receiving no help from the other Crusader states, the city was again lost in November, as Joscelin's expedition was driven out by Zengi's son Nur ad-Din. The Second Crusade, called in response to the fall of Edessa, shifted its focus to Damascus. In 1150 while en route to Antioch to enlist help, Joscelin II was taken prisoner by Nur-ed-Din's Turkomans. Joscelin II was taken to the city of Aleppo where he was led before a hostile crowd and publicly blinded. He spent the remaining nine years of his life in captivity in a Muslim prison. He died in the dungeons of the Citadel of Aleppo in 1159.
