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 King Dahir with an army of 4,000 Rajputs and 3,000 Brahmins.

On the eight day, Muhammed ibn Qasim received the letter from Al-Hajjaj and eventually the Umayyad Army scaled the walls of Debal and its people surrendered.
