Ibrahim capitalized on his success by sending raiding parties against various strongholds in the vicinity, forcing either their capitulation and destruction or the payment of tribute. In this manner, Demona, Rometta, and Aci were captured or forced to pay tribute in token of submission. The locals were encouraged to convert to Islam, or, where they had left their forts and fled for the mountains, the walls were torn down and the wells blocked with stones to make them uninhabitable.[16][29]
