 The abandonment of the city left behind a cache of weapons in the Qishla of Mecca which were recovered by Saudi forces.Ibn Saud declared that Ali bin Hussein was to leave Hejaz as a pre-requisite for peace and that the invasion of Hejaz was to 'guarantee the liberty of pilgrimage and to settle the destiny of the Holy Land in a manner satisfactory to the Islamic world'.Following the capture of Mecca, Ali and the remaining Hejazi forces were concentrated in the port city of Jeddah which would later be besieged in January 1925 by the Saudi forces.
