Now we come to a period of Lopez's career which it is difficult to harmonize with the whole story of his after life. The only plausible explanation seems to be that he was only a boy, and that Bolivar's army was suffering such reverses that the only way in which Lopez could save his own life was by joining forces with the Spaniards, which he did. One would have thought that after the valiant part he played in the defense of Valencia, he would cast his lot with the insurgents. No writer of the period gives us any real explanation of his course. But whatever the motive, Lopez became a Spanish soldier, a fact which later was to be of tremendous value to him, because it enabled him to visit Spain, to rise high in the service, to hold exalted positions in the Spanish court, and to obtain an insight into the cruelties and injustices perpetrated by the men who were the oppressors of the country which he was to adopt as his own, and the salvation of which he was to make his life work, which he could have gained in no other way. His action may have been precipitated by the fact that the people of Valencia did not understand the straits in which Bolivar found himself, but felt that he had deliberately deserted them. Through the long struggle which ended in the evacuation of Caracas by Spain in 1823, Lopez fought with the Spaniards. So brilliant was his service that he was at the age of twenty-three given the rank of major. The story is told that early in the war, when he was a mere private, in an attack against a position which was defended by field works, the Spanish forces were divided, in an effort to take two bastions upon the capture of which victory depended. But there was not sufficient ammunition, and that of one of the divisions became exhausted, so that it was necessary to obtain a fresh supply from the other division. This information was signaled, and the leader of that portion of the attackers which must now supply the other, called for volunteers. In order to get the relief through it was necessary to lead three mules, which were tied together Spanish fashion, the head of the second mule to the tail of the first one, and the head of the third to the tail of the second, past a position where they were exposed to the hot fire of the opposing army. Lopez volunteered. When he reached the most dangerous part of his course, the mule in the center was struck by the enemy's fire and fell dead. Lopez did not hesitate, but with the bullets singing about him--the insurgents in that party must have been singularly bad marksmen, or perhaps their guns were not of an efficient pattern--he cut out the dead animal and, tying the two remaining mules together, safely reached his destination and delivered the ammunition to the commander. He was not injured, but his gun had been broken by a chance shot, his clothes were riddled with bullets, one of which had passed through his hat within an inch of his head, and both of his mules were so severely
