would cheerfully do, but stain themselves with so awful a massacre was to place themselves outside the pale of humanity for ever.  It was seldom that they crossed his mood, and Barbarossa listened in frowning silence, accepting as a partial excuse that time pressed, and to put to death twenty thousand persons would occupy longer time than they could spare.  On the morrow a battle was fought which, as Kheyr-ed-Din anticipated, ended in the complete rout of the Moslems.  Everywhere the Corsair King was in the forefront of the battle, and it is said that he disposed of fifty thousand men on this occasion; but this is probably an exaggeration, and in any case the bulk of his forces consisted of those African levies which, in a pitched battle against European troops, were practically useless owing to their want of discipline and cohesion.  Very soon the hosts of the Emperor had prevailed, and the Arabs and Berbers had fled back into the wilderness from whence they had come and whither it was useless to pursue.  Barbarossa, at the head of such of his corsairs and Turks as were left—­a number estimated at some three to four thousand—­burst through all opposition and also escaped, travelling so rapidly that pursuit was abandoned almost at once.  And then the event happened which the Moslem leader had foreseen:  some of the Christian captives managed to get free from their shackles within the city and released others; they overpowered those left to guard them, and threw open the gates to the soldiery of the Emperor.

Then occurred one of those awful horrors of which this time was so prolific:  before Charles or his generals could prevent them the soldiery had swept into the town and commenced to slay, to plunder, and to ravish, without distinction of age, sex, or nationality.  Ostensibly these Christian warriors had come to rescue the inhabitants of Tunis from the oppression of Barbarossa, but while that chieftain was in full flight across the mountains to Bona, those by whom he had been defeated entered the town, which they had come to save, and perpetrated a massacre so awful that it is said that no less than thirty thousand people perished.  It is a terrible blot on the escutcheon of the Emperor; as, although he and his generals deprecated the massacre—­and indeed to do them justice tried to prevent it—­this is no excuse for allowing their men to get out of hand, when they must have been aware of the inevitable result:  as the Moslem corsairs at their worst were equalled in their iniquities by the European soldiery, once the strong hand of discipline had relaxed its grip.
