Cause

After their defeat at the Battle of Ajnadayn, Byzantine forces retreated and regrouped near Pella and Scythopolis in the Jordan Valley. The Rashidun Muslim army pursued them there, prompting the Byzantines to flood the terrain by cutting irrigation ditches in an attempt to impede the advancing Muslim cavalry and buy time to reorganize their defenses.

Event

Arab Muslim forces of the Rashidun Caliphate engaged the regrouped Byzantine army at or near Pella and Scythopolis in December 634 or January 635. Despite the waterlogged and muddied ground created by the Byzantine flooding tactic, which hampered Muslim cavalry movement, the Muslims pressed their assault and ultimately defeated the Byzantine forces, who suffered reported enormous casualties.

Consequence

Following the battle, Pella was captured outright, while Beisan and nearby Tiberias capitulated after brief sieges conducted by Muslim detachments. The victory secured Rashidun control over the Jordan Valley and accelerated the broader Muslim conquest of Byzantine Syria.
