The practicality which showed itself in his general aims appeared also in his mode of working. Caesar, it was observed, when anything was to be done, selected the man who was best able to do it, not caring particularly who or what he might be in other respects. To this faculty of discerning and choosing fit persons to execute his orders may be ascribed the extraordinary success of his own provincial administration, the enthusiasm which was felt for him in the North of Italy, and the perfect quiet of Gaul after the completion of the conquest. Caesar did not crush the Gauls under the weight of Italy. He took the best of them into the Roman service, promoted them, led them to associate the interests of the Empire with their personal advancement and the prosperity of their own people. No act of Caesar's showed more sagacity then the introduction of Gallic nobles into the Senate; none was more bitter to the Scipios and Metelli, who were compelled to share their august privileges with these despised barbarians. It was by accident that Caesar took up the profession of a soldier; yet perhaps no commander who ever lived showed greater military genius. The conquest of Gaul was effected by a force numerically insignificant, which was worked with the precision of a machine. The variety of uses to which it was capable of being turned implied, in the first place, extraordinary forethought in the selection of materials. Men whose nominal duty was merely to fight were engineers, architects, mechanics of the highest order. In a few hours they could extemporize an impregnable fortress on an open hillside. They bridged the Rhine in a week. They built a fleet in a month. The legions at Alesia held twice their number pinned within their works, while they kept at bay the whole force of insurgent Gaul, entirely by scientific superiority. The machine, which was thus perfect, was composed of human beings who required supplies of tools, and arms, and clothes, and food, and shelter, and for all these it depended on the forethought of its commander. Maps there were none. Countries entirely unknown had to be surveyed; routes had to be laid out; the depths and courses of rivers, the character of mountain passes, had all to be ascertained. Allies had to be found among tribes as yet unheard of. Countless contingent difficulties had to be provided for, many of which must necessarily arise, though the exact nature of them could not be anticipated. When room for accidents is left open, accidents do not fail to be heard of. Yet Caesar was never defeated when personally present, save once at Gergovia, and once at Durazzo; and the failure at Gergovia was caused by the revolt of the Aedui; and the manner in which the failure at Durazzo was retrieved showed Caesar's greatness more than the most brilliant of his victories. He was rash, but with a calculated rashness, which the event never failed to justify. His greatest
