In April 1191, al-Manṣūr launched a second attempt to reconquer Silves. He first endeavoured to take Alcácer do Sal by force, before settling down to a siege. The defenders soon capitulated on terms and were given their liberty. Unliked Torres Novas, which he had razed, Alcácer do Sal was garrisoned by the caliph and placed under the command of Muḥammad ibn Sı̄dray ibn Wazı̄r. For its upkeep, the caliph designated certain funds from Ceuta and Seville.
