The Battle of the Bridge or the Battle of al-Jisr (Arabic: معركة الجسر) was fought at the bank of the Euphrates between Arab Muslims, led by Abu Ubayd al-Thaqafi, and the Persian Sasanians, led by Bahman Jaduya. It is traditionally dated to the year 634 and was the only major Sasanian victory over the invading Rashidun Caliphate army.
== Context == The Muslim forces had already taken Hira and assumed control of the surrounding Arab-inhabited areas of Mesopotamia, on the banks of the Euphrates. The fall of Hira shocked the Persians, as the "youthful Yazdgard, began to take the business of the Arabs more seriously." Yazdgard sent forces to the Arab border areas and looked to be gaining the upper hand, as Al-Muthanna had to call for reinforcements from Medina. The new caliph, Umar, sent Abu Ubayd to Mesopotamia to take command from Al-Muthanna. He encountered the main Persian force under Bahman Jaduya near what is the present site of Kufa. The two forces faced each other on opposing banks of the Euphrates. As it was crossed by a bridge, the battle came to be known as the Battle of the Bridge.
== Battle == Bahman invited Abu Ubayd to decide who should cross the river. The latter took the initiative and crossed the river aggressively, which proved to be disastrous for his forces. According to accounts, the sight of the elephants in the Persian army frightened the Arabs' horses. A white elephant apparently tore Abu Ubayd from his horse with its trunk and trampled him underfoot during his misguided attempt to attack its trunk. The death of their commander and the inability of the Arab troops to push back the Persians, who had formed a rigid line close to the bridge, led the Arabs to panic and flee. Abu Ubayd's command was taken by al-Hakam and Jabr, his brother and son respectively and later Al-Muthanna. According to tradition, Al-Muthanna remained to fight so that the Arabs could repair the bridge and flee, losing 4,000 men, but any accurate estimates of the figures involved in this and other contemporaneous battles are not known. Around 3,000 Arab Muslims were carried away by the river. Bahman Jaduya did not pursue the fleeing Arab army.
