It may have been that the Emperor was displeased with this excess of zeal on the part of his army; but, if it were so, the chroniclers are silent concerning the matter, being far too busy singing the praises of the Cæsar to think of such a trifle as the massacre of most of the persons whom he had come to deliver. The wretched inhabitants of Tunis must have found it somewhat difficult to distinguish between the corsair, who killed three thousand of their fellow townsmen, and the Christian Emperor, who had massacred ten times that number. Charles, however, reaped great glory from an expedition which had but one good result, which was, that he succeeded in rescuing twenty thousand captives; these men, very naturally, on their return to their homes in every corner of Europe, magnified the wonderful deeds of that prince who had been instrumental in securing their release, and the massacre of the Tunisians was conveniently ignored. Charles had defeated Barbarossa and expelled him from Tunis; he had now displayed his magnanimity and altruism by the terms which he imposed on the miserable Muley Hassan. As far as that individual was concerned, he certainly deserved nothing better; but, as a _finale_ to an expedition blessed by the Pope, and looked upon almost in the light of a modern crusade, it certainly displays a remarkably keen eye for the main chance. The preamble of the treaty runs as follows: “That the King of Tunis, recognising that he had been expelled from his kingdom by Barbarossa, and that the Emperor in person, with a powerful armada, had come and expelled this tyrant, taking from him the fortress and town of Tunis and restoring them to the King Muley Hassan: that this monarch is most grateful for so magnificent a service, and in recognition thereof contracts to liberate all Christian captives who may be in his realm, to give them a free passage to their homes, and from this time forward binds himself to extend to all Christians kind and generous treatment.” There can be no exception taken to this, which was the least which the Emperor had the right to expect; but this was only, as we have said, the preamble. Muley Hassan was further made to contract to hold his kingdom in fee to the Spanish Crown, to covenant that no corsair should use his ports for any purpose whatsoever, that the Emperor should not only retain the Goletta but that all other fortified seaports should be put into his hands, that the King of Tunis should in future pay twelve thousand crowns per annum ‘for the subsistence of the Spanish garrison of the Goletta, that he should enter into no alliance with the enemies of the Emperor, and should annually present, as an acknowledgment of his vassalage, six Moorish horses and six hawks.
