The army of Muza was now augmented to about eighteen thousand horsemen, but he took with him but few foot-soldiers, leaving them to garrison the conquered towns. He met with no resistance on his entrance into Lusitania. City after city laid its keys at his feet and implored to be received in peaceful vassalage. One city alone prepared for vigorous defense, the ancient Merida, a place of great extent, uncounted riches, and prodigious strength. A noble Goth named Sacarus was the governor,—a man of consummate wisdom, patriotism, and valor. Hearing of the approach of the invaders, he gathered within the walls all the people of the surrounding country, with their horses and mules, their flocks and herds, and most precious effects. To insure for a long time a supply of bread, he filled the magazines with grain, and erected wind-mills on the churches. This done, he laid waste the surrounding country to a great extent, so that a besieging army would have to encamp in a desert. When Muza came in sight of this magnificent city, he was struck with admiration. He remained for some time gazing in silence upon its mighty walls and lordly towers, its vast extent, and the stately palaces and temples with which it was adorned. “Surely,” cried he, at length, “all the people of the earth have combined their power and skill to embellish and aggrandize this city. Allah Achbar! Happy will he be who shall have the glory of making such a conquest!” Seeing that a place so populous and so strongly fortified would be likely to maintain a long and formidable resistance, he sent messengers to Africa to his son Abdalasis, to collect all the forces that could be spared from the garrisons of Mauritania, and to hasten and reinforce him. While Muza was forming his encampment, deserters from the city brought him word that a chosen band intended to sally forth at midnight and surprise his camp. The Arab commander immediately took measures to receive them with a counter surprise. Having formed his plan, and communicated it to his principal officers, he ordered that, throughout the day, there should be kept up an appearance of negligent confusion in his encampment. The outposts were feebly guarded; fires were lighted in various places, as if preparing for feasting; bursts of music and shouts of revelry resounded from different quarters, and the whole camp seemed to be rioting in careless security on the plunder of the land. As the night advanced, the fires were gradually extinguished, and silence ensued, as if the soldiery had sunk into deep sleep after the carousal. In the mean time, bodies of troops had been secretly and silently marched to reinforce the outposts; and the renegado Magued, with a numerous force, had formed an ambuscade in a deep stone quarry by which the Christians would have to pass. These preparations being made, they awaited the approach of the enemy in breathless silence.
