Two hours upstream, so Tafas told me, was the throat where Wadi Fura issued from the last granite hills, and there had been built a little village, Khoreiba, of running water channels and wells and palm-groves, inhabited by a small population of freedmen engaged in date husbandry. This was important. We had not understood that the bed of Wadi Fura served as a direct road from near Medina to the neighbourhood of Rabegh. It lay so far south and east of Feisal’s supposed position in the hills that he could hardly be said to cover it. Also Abdulla had not warned us of the existence of Khoreiba, though it materially affected the Rabegh question, by affording the enemy a possible watering-place, safe from our interference, and from the guns of our warships. At Khoreiba the Turks could concentrate a large force to attack our proposed brigade in Rabegh.
