Although the conquerors professed the same religion, bowed to the same prophet, and waged war for the same great calif in the East, yet they were not all of the same nationality, for in the army of invasion were not only Arabs, but Moors, Egyptians, and Syrians. In time, however, all came to be called by the name of Moors, though their differences of birth and divergence of views led to serious quarrels among them. The first estrangement was when Musa, the emir, finding that Tarik had disobeyed his orders, and, instead of returning to Africa after defeating the Goths in battle and acquiring vast plunder, had pursued his conquests toward the north, hastily gathered another army and followed on his tracks. Musa found, however, that though Tarik had followed up his victory by effectually scattering the defeated Goths, and even taking the capital city, Toledo, there was yet room for another conqueror to operate; so, instead of immediately pursuing Tarik, after he had landed he made a detour through Andalusia and took Medina Sidonia and the rich Roman city of Seville. Then, though gorged with plunder enough to have satisfied a king, he pushed on after and overtook the recreant Tarik at the city of Toledo. “I gave thee orders to make a foray only, then return to Africa,” he said to the veteran, “yet thou hast marched through all this territory without my permission.” The warrior received this reproof in silence, and for a time a truce was made between them; they pushed on their conquests, the one into the northwest, the other into the north and east, until only the Pyrenees separated them from the country of the Gauls. Between them they brought all Spain under subjection, with the exception of certain remote districts, which they thought too small or too distant to be attacked. But it was within the confines of these small mountain valleys of the northwest that, protected by their rugged barriers, the defeated Goths halted and found a home, and gathered as a nucleus for future forays upon their enemies; as we shall see. When the country had been practically conquered, the quarrel between Musa and Tarik was renewed; finally it reached the ears of the Calif at Bagdad that his most valiant generals were fighting like jackals over their prey, and he summoned them both to the Orient, there to give account of themselves. It would seem that gratitude was a sentiment entirely foreign to the Arab character, as instanced not only on this occasion, but on many another during the conquest and continuance of the Moors in Spain; for, in spite of his inestimable services to the califate, notwithstanding he had given to the Moslems a new country as their own, and had extended the sway of Islam westward to the Atlantic, Musa was degraded, even sentenced to death, and finally ended his life in poverty.
