Battle of Walaja

The Battle of Walaja (Arabic: معركة الولجة) was a battle fought in Mesopotamia (Iraq) in May 633 between the Rashidun Caliphate army under Khalid ibn al-Walid and Al-Muthanna ibn Haritha against the Sassanid Empire and its Arab allies. In this battle the Sassanid army is said to have been two times the size of the Muslim army.
