continent, and against forces superior in both numbers and equipment. San Martin's first step was to organise and drill some good regiments in Buenos Aires. He selected the finest physical and moral specimens of youth that the province afforded and subjected them to a rigid discipline. After his ruthless pruning only the born soldiers remained, and this select corps furnished generals and officers for the wars that followed. On succeeding Belgrano in command of the army of the north, San Martin saw at once that all attempts to conquer Peru by an advance through Bolivia were foredoomed to failure. A campaign over a mountainous plateau, with the Spaniards in possession of the strategic points, and the inhabitants divided in their sympathies, would be suicidal. On the other hand, to attack and defeat the Spanish forces in Peru itself was absolutely necessary. The three hundred thousand inhabitants of Argentina, distracted by intestine warfare, could not hope indefinitely to resist the Spanish power, backed by secure possession of the rest of the continent. Decisive victories were necessary to encourage the partisans of independence in Chile, Peru, Bolivia, and Ecuador. San Martin's solution of the problem was to organise an army on the eastern slope of the Andes; to invade Chile; to drive the Spaniards thence, and make that country the base of further operations; to improvise a fleet and with it gain command of the Pacific; and, finally, to attack Peru from the coast. The scheme seemed complicated, but San Martin was one of those rare geniuses born with a capacity for taking infinite pains, and his pertinacity was indefatigable. He foresaw and provided against every contingency and carried his plan to a triumphant conclusion. The story of the liberation of South America within the succeeding eight years might be completely told in the form of two biographies--San Martin's and Bolivar's.
