The Battle of Walaja (Arabic: معركة الولجة) was fought in Mesopotamia in May 633 CE between the forces of the Rashidun Caliphate commanded by Khalid ibn al-Walid and the Sasanian Empire alongside its Arab client allies. The battle is widely regarded as one of the most tactically sophisticated engagements of the Early Muslim conquests. Khalid secured a decisive victory by employing a double-envelopment maneuver—an uncommon battlefield tactic most famously associated with Hannibal’s victory over the Romans at the Battle of Cannae. The defeat weakened Sasanian control in lower Mesopotamia and contributed to the subsequent Muslim advance into Persian territory.
