[2] The oasis of al-Hasa was conquered from an Ottoman garrison, which had controlled the area since 1871.
[3] The Shia religious community leaders of al-Hasa negotiated a surrender and recognition of the Saudi political authority in exchange for leniency and religious freedom, which was granted at the time by Ibn Saud.
The Ottoman soldiers were deceived by the British’s advice and promise, so they chartered ships and returned to the port of Al-Uqair.
They were confronted by a company headed by Bin Nader from Ibn Saud’s forces and clashed with them in a bitter fight that resulted in a number of deaths and the capture of thirty Ottoman soldiers.
The news reached Ibn Saud while he was in Al-Ahsa, so he went out to Al-Uqair and released the Turkish prisoners.
