In truth the Turks were meeting with unguessed difficulties. Their headquarters were faced by a heavy sick rate among the men, and a growing weakness of the animals: both symptoms of overwork and lack of decent food. Always the activity of the tribesmen behind their back hampered them. Clans might sometimes fall away from the Arab cause, but did not therefore become trustworthy adherents of the Turks, who soon found themselves in ubiquitously hostile country. The tribal raids in the first fortnight of January caused them average daily losses of forty camels and some twenty men killed and wounded, with corresponding expense in stores.
