The Battle of the Baggage (Arabic: ﻳﻮﻡ ﺍلاﺛﻘﺎﻝ, romanized: Yawm al-athqāl) was fought between the forces of the Umayyad Caliphate and the Turkic Türgesh tribes in September/October 737. The Umayyads under the governor of Khurasan, Asad ibn Abdallah al-Qasri, had invaded the Principality of Khuttal in Transoxiana, and the local ruler called upon the Türgesh for aid. The Umayyad army retreated in haste before the Türgesh arrived, managing to cross the Oxus River just in time, while their rearguard engaged the pursuing Türgesh.
