The siege of Debal, also known as the siege of Debul, took place in the autumn of 711 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 inhabitants of the order on the order of Governor of Iraq Al-Hajjaj and captured it.
In 711, Muhammed ibn Qasim marched towards Debal with 6,000 Syrian cavalry and 3,000 camelry with a good number of Arab soldiers. The city was commanded by a nephew of Dahir with an army of 4,000 Rajputs and 3,000 Brahmins.{{Cite book |last=Wolseley Haig |url=http://archive.org/details/cambridgehistory035492mbp |title=The Cambridge History Of India Volume III |publisher=At The University Press Cambridge |others=BRAOU, Digital Library Of India |pages=2}}{{Cite book |last=Board |first=Pratiyogita Darpan Editorial |url=https://books.google.com/books?id=4TA_WbrHHDsC |title=Pratiyogita Darpan Extra Issue Series-16 Indian History–Medieval India |publisher=Upkar Prakashan |pages=36 |language=en}} The Umayyad forces encamped outside the city walls for seven days waiting for the permission letter to attack.
