Khuzestan Central Persia Caucasus Pars Khorasan Other geographies The Battle of the Bridge or the Battle of al-Jisr (Arabic: معركة الجسر; Persian: نبرد پل) was fought at the bank of the Euphrates river between Arab Muslims led by Abu Ubaid al-Thaqafi, and the Persian Sasanian forces led by Bahman Jaduya.

The Muslim forces had already taken Hira and assumed control of the surrounding Arab-inhabited areas of Mesopotamia, on the banks of the Euphrates.

"[9] 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.

He encountered the main Persian force under Bahman Jaduya, near what is the present site of Kufa.

[3] According to tradition, Al-Muthanna remained to fight so that the Arabs could repair the bridge and flee losing 4,000 men, although any accurate estimates of the figures involved in this and other contemporaneous battles are not known.
