As the time passed, by autumn the Arab middle class had exhausted its resources. Under these circumstances, the Mandatory government was looking for an intermediary who might help persuade the Arab Higher Committee to end the rebellion. Al-Husseini and the Committee rejected King Abdullah of Transjordan as mediator because of his dependence on the British and friendship with the Zionists, but accepted the Iraqi Foreign Minister Nuri as-Said. As Wauchope warned of an impending military campaign and simultaneously offered to dispatch a Royal Commission of Inquiry to hear the Arab complaints, the Arab Higher Committee called off the strike on 11 October. When the promised Royal Commission of Inquiry arrived in Palestine in November, al-Husseini testified before it as chief witness for the Arabs.
