Imad ad-Din Zengi
Imad ad-Din Zengi, atabeg (governor) of Mosul, invaded the County of Tripoli, plundering the capital and the neighboring region in 1133. Pons wanted to stop the invaders near Rafaniya, but his army was almost annihilated. After this catastrophic defeat, he fled first to Montferrand, and soon to Tripoli, while Zengi laid siege to the fort of Montferrand. Pons sought Fulk's assistance and the arrival of the Jerusalemite army forced Zengi to lift the siege and to withdraw his troops from the county.
