This plan had many obvious advantages, the most important of which was the aid and protection that would be given to the army, at every stage of its progress, by the guns of perhaps thirty or forty ships of war. In the opinion of naval officers, Admiral Sampson's cruisers and battle-ships could sweep the country ahead of our advance with such a storm of shot and shell that the Spaniards would not be able to hold any position within a mile of the coast. All that the army would have to do, therefore, would be to occupy the country as fast as it was cleared by the fire of the fleet, and then open the harbor to the latter by cutting communication with the submarine mines which were the only effective defense that the city had on the water side. General Shafter's army, moreover, would be all the time on high, sea-breeze-swept land, and therefore comparatively safe from malarial fever, and it would not only have a railroad behind it for the transportation of its supplies, but be constantly within easy reach of its base by water. Why this plan was eventually given up I do not know. In abandoning it General Shafter voluntarily deprived himself of the aid that might have been rendered by three or four hundred high-powered and rapid-fire guns, backed by a trained fighting force of six or eight thousand men. I do not know the exact strength of Sampson's and Schley's combined fleets, but this seems to me to be a conservative estimate. A prominent officer of the battle-ship _Iowa_ told me in Santiago, after the surrender, that the fighting ships under Admiral Sampson's command, including the auxiliary cruisers and mosquito fleet, could concentrate on any given field a fire of about one hundred shells a second. This included, of course, small projectiles from the rapid-fire and one-pound machine guns. He did not think it possible for Spanish infantry to live, much less fight, in the field swept by such a fire, and this was his reason for believing that the fleet could have cleared the way for the army if the latter had advanced along the coast instead of going back into the interior. The plan of attack by way of Aguadores and Morro was regarded by the foreign residents of Santiago as the one most likely to succeed; and a gentleman who lived eight years at Daiquiri, as manager of the Spanish-American Iron Company, and who is familiar with the topography of the whole region, writes me: "I have always thought that the great mistake of the Santiago campaign was that they assaulted the city at its most impregnable point, instead of taking possession of the heights at Aguadores, which would have been tantamount to the fall of Morro, the possession of the harbor entrance and of the harbor itself. The forces of the Spaniards were not sufficient to maintain any considerable number of men there, and it seems to me that, with the help of the fleet shelling the heights, they could have been reached very easily along the Juragua Railroad.
