The Siege of Debal, also known as the Siege of Debul, took place in the autumn of 712 AD, in which the Umayyad forces under Muhammed Ibn al-Qasim besieged Debal, a city under the Brahmin dynasty of Sindh ruled by Raja Dahir. The Umayyads defeated the Chach loyalists on the orders of the governor of Iraq, Al-Hajjaj ibn Yusuf, and captured it.
