Battle of Fahl (Pella)

The Battle of Fahl (ancient Pella) was fought in the Jordan Valley in 13 AH after the fall of Damascus. Byzantine forces flooded the plain to hinder the Muslim cavalry, but Abu Ubayda's forces waded through the marshes and defeated them. This battle effectively ended Byzantine military resistance in northern Palestine and Transjordan. The victory at Fahl, combined with the fall of Damascus and the earlier Battle of Yarmouk, gave Muslims control of the entire Levant region south of the Taurus Mountains.
