At length the time came when the forces of the Koreish and the Moslems were again to meet at Badr. But the year was one of great draught, and the Koreish were desirous that the expedition should be deferred to a more favorable season. Accordingly the Koreish engaged Naeem, an Arab of a neutral tribe, to repair to Medina, and there to give forth an exaggerated account of the preparations of the Koreish, in the hope that, with the field of Ohad fresh in memory, it might deter the Moslems from setting out to meet them. But Mohammad, with a force of fifteen hundred men and only ten horses, set forth for Badr. The Koreish, who never appeared mortified at the triumph of Mohammad, began to project another grand attack upon him. [Sidenote: 13. The Koreish again attack Medina with a large army. Mohammad defends the city. The enemy retire. (Ditch or Nations.--A.H., V.)] The winter season in the next year was chosen for the renewal of hostilities by the Koreish. They joined an immense force of the Bedouin tribes (the entire army was estimated at ten thousand), marched against Mohammad, and besieged Medina. Mohammad defended the city by digging a Ditch. The army of Medina was posted within the trench, and that of the Koreish encamped opposite them. In the meantime Abu Sofian succeeded in detaching the Jewish tribe of Koreiza from their allegiance to Mohammad. The danger to Medina from this defection was great. The enemy made a general attack, which was repulsed. Bad weather set in, and Abu Sofian ordered the allied force to break up. The enemy retired, and never came again to attack the Moslems. This, therefore, was the last war of aggression on the part of the Koreish, and of defence on the part of Mohammad. [Sidenote: 14. Mohammad, with his followers, advanced to perform the lesser pilgrimage of Mecca. The Koreish opposed Mohammad, who returned disappointed.--A.H. VI.]
