Some tribal leaders would agree to fight for the British and accept their payment and weapons and soon afterwards begin fighting for the Ottomans because they offered to pay the tribes more. This fickleness showed that many of the tribes were not interested in Arab unity, the ultimate goal of Sharif Husayn, but rather just wanted to be paid. While this made things more difficult for the Sharifian Army, Faysal's strong negotiating skills won many tribal chieftains over, giving the Hashemites the support they needed to challenge the Ottomans.[9]
