I was obliged to remain at Mekka a whole month after the departure of the Hadj, waiting for another opportunity of proceeding to Medina. I might have easily gone from Djidda, by sea, to Yembo; but I preferred the journey by land. At this time the people of the Hedjaz were kept in anxious suspense, on account of Mohammed Aly, who was preparing to set out from Mekka, in person, against the Wahabys. They knew that, if his expedition should fail, the Bedouins of the Hedjaz would immediately resort to their wonted practices, and cut off the route to the interior from all travellers; and experience had also taught them, that if the Wahabys obtained possession of the country a second time, the town of Mekka alone could indulge in any hope of escaping from being plundered. These considerations retarded the departure of caravans for Medina. A strong caravan usually leaves Mekka on the 11th of Moharrem, (corresponding this year with the 2nd of January, 1815,) the day after the opening of the Kaaba, which always takes place on the 10th of Moharrem, or the day called Ashour. Towards the end of December, the inhabitants were alarmed by a false report of the arrival of a Wahaby force, by the way of the seacoast, from the south: soon after, in the first days of January, 1815, Mohammed Aly set out from Mekka. He met the Wahaby army, four days after, at Byssel, in the neighbourhood of Tayf, where he gained [p.289] the complete victory of which I have elsewhere given the details; this was no sooner known at Mekka, than the caravan for Medina, which had long been prepared, set out, on the 15th of January.
