The mercenaries of the caliph were dismayed at the approach of an enemy who neither asked nor accepted quarter; and the difference between, them in fortitude and patience, is expressive of the change which three centuries of prosperity had effected in the character of the Arabians.

Such troops were discomfited in every action; the cities of Racca and Baalbec, of Cufa and Bassora, were taken and pillaged; Bagdad was filled with consternation; and the caliph trembled behind the veils of his palace.

In a daring inroad beyond the Tigris, Abu Taher advanced to the gates of the capital with no more than five hundred horse.

By the special order of Moctader, the bridges had been broken down, and the person or head of the rebel was expected every hour by the commander of the faithful.

His lieutenant, from a motive of fear or pity, apprised Abu Taher of his danger, and recommended a speedy escape.
