The Battle of Ajnadayn (Arabic: معركة أجنادين), fought on July 30, 634, in an unknown location close to Beit Guvrin in present day Israel; it was the first major pitched battle between the Byzantine (Roman) Empire and the army of the Arab Rashidun Caliphate. The result of the battle was a decisive Muslim victory. The details of this battle are mostly known through Muslim sources, such as the ninth century historian Al-Waqidi.
According to David Nicolle, the Rashidun army left the capital Medina probably in the autumn of 633, but possibly at the beginning of 634. They first engaged and defeated the Byzantines at Dathin on February 4; after that Emperor Heraclius, then stationed in Emesa (now Homs, Syria), had reinforcements sent south to protect Caesarea Maritima. As a possible reaction, commander Khalid ibn al-Walid was ordered to interrupt operations against the Sassanian Empire and reach Syria, which brought him to engage and defeat the Byzantine-allied Ghassanids by April 24, permitting him to enter almost unopposed in Bosra. At this point, Khalid converged with several armies, led by generals such as Abu Ubaydah ibn al-Jarrah, Yazid ibn Abu Sufyan, Amr ibn al-A'as and Shurahbil Ibn Hasanah.
Khalid united with Amr's forces in a place known traditionally as Adjnadayn. No geographer has attested such a place, which probably originates from a conflation of the Arab plural adjinad (armies). All the same, due to Arab sources the location of the battlefield has been identified with a place in the Wadi l'Samt, the biblical Valley of Elah, 9 km from modern Bet Guvrin in Israel.
Regarding the primary sources, there is an absence of any of Byzantine provenance; possibly, according to Walter Kaegi, because what Byzantine material exists may conflate the battle with other Byzantine defeats, such as Dathin and Yarmouk. The earliest source appears to be an entry in the Frankish, Chronicle of Fredegar, compiled in 658-660, unless this is a possible interpolation.
The two armies
Regarding the strength of the confronting armies, H. A. R. Gibb, in the Encyclopaedia of Islam argues that, at best, both forces were made up of 10,000 men, and that Muslim sources are "highly exaggerated". Concerning the size of the Byzantine army, Nicolle also accepts this estimate, as he puts it at 9,000-10,000, but instead considers the Rashidun forces to have been 15,000-18,000, a number placed at 20,000 by David Morray in the Oxford Companion to Military History.
