On the hills above Santiago the American Army had now only the land forces of the Spaniards to contend with. Shafter's demand for unconditional surrender met with a refusal, and there ensued a week of military quiet. During this time General Shafter conducted a correspondence with the War Department, in judging which it is charitable to remember that the American commander weighed three hundred pounds, that he was sweltering under a hot sun, and that he was sixty-three years old, and sick. Too humane to bombard Santiago while Hobson and his men were still in Spanish hands, he could not forgive Sampson for not having forced the narrow and well-mined channel at the risk of his fleet. The War Department, sharing Shafter's indignation, prepared to attempt the entrance with one of its own transports protected by baled hay, as had been done on the Mississippi during the Civil War. Shafter continued to be alarmed at the situation. Without reenforcements he could not attack, and he proposed to allow the Spaniards to evacuate. The War Department forbade this alternative and, on the 10th of July, he began the bombardment of Santiago. The Secretary of War then hit upon the really happy though quite unmilitary device of offering, in return for unconditional surrender, to transport the Spanish troops, at once and without parole, back to their own country. Secretary Alger was no unskillful politician, and he was right in believing that this device, though unconventional, would make a strong appeal to an army three years away from home and with dwindling hopes of ever seeing Spain again. On the 15th of July a capitulation was agreed upon, and the terms of surrender included not only the troops in Santiago but all those in that military district--about twenty-four thousand men, with cannon, rifles, ammunition, rations, and other military supplies. Shafter's recommendation that the troops be allowed to carry their arms back to Spain with them was properly refused by the War Department. Arrangements were made for Spanish ships paid by the United States to take the men immediately to Spain. This extraordinary operation was begun on the 8th of August, while the war was still in progress, and was accomplished before peace was established. The Santiago campaign, like the Mexican War, was fought chiefly by regulars. The Rough Riders and the Seventy-first New York Regiment were the only volunteer units to take a heavy share. Yet the absence of effective staff management was so marked that, as compared with the professional accuracy shown by the navy, the whole campaign on land appears as an amateur undertaking. But the individual character of both volunteers and regulars was high. The American victory was fundamentally due to the fighting spirit of the men and to the individual initiative of the line and field officers.
