At this critical juncture, the naval forces once more distinguished themselves, and made further bloody fighting on land unnecessary, by destroying Cervera's fleet which attempted to make its escape from the Santiago harbor on the morning of July 3. The American ships were then in charge of Commodore Schley, for Admiral Sampson had left watch early that morning for a conference with General Shafter; and the sailors acquitted themselves with the same skill that marked Dewey's victory at Manila. Within less than four hours' fighting all the Spanish ships were destroyed or captured with a loss of about six hundred killed and wounded, while the Americans sustained a loss of only one man killed and one wounded. This victory, of course, marked the doom of Santiago, although it did not surrender formally until July 17, after two days' bombardment by the American ships.
The fall of Santiago ended military operations in Cuba, and General Miles, who had come to the front in time to assist General Shafter in arranging the terms of the surrender of Santiago, proceeded at once to Porto Rico. He was rapidly gaining possession of that Island in an almost bloodless campaign when news came of the signing of the peace protocol on August 12. Unfortunately it required longer to convey the information to the Philippines that the war was at an end, and on the day after the signature of the protocol, that is, August 13, General Merritt and Admiral Dewey carried Manila by storm.
As early as July 26, 1898, the Spanish government approached President McKinley through M. Cambon, the French ambassador at Washington, and asked for a preliminary statement of the terms on which the war could be brought to a close. After some skirmishing, in which Spain reluctantly yielded to the American ultimatum, a peace protocol was signed on August 12, to the effect that Cuba should be independent, Porto Rico ceded to the United States, and Manila occupied pending the final negotiations, which were opened at Paris by special commissioners on October 1.
When the commissioners met according to arrangements, the government of the United States apparently had not come to a conclusion as to the final disposition of the Philippines. The administration was anxious not to go too far in advance of public opinion, at least so far as official pronunciamento was concerned, although powerful commercial interests were busy impressing the public mind with the advantages to be derived from the retention of the distant Pacific Islands. In his instructions to the peace commissioners, on the eve of their departure, Mr. McKinley, while denying that there had originally been any intention of conquest in the Pacific, declared that the march of events had imposed new duties upon us, and added: "Incidental to our tenure in the Philippines is the commercial opportunity to which American statesmanship cannot be indifferent. It is just to use every legitimate means for the enlargement of American trade." While stating that the possession of territory was less important than an "open door" for trade purposes, he concluded by instructing the commissioners that the United States could not "accept less than the cession in full right and sovereignty of the Island of Luzon."
The peace commissioners were divided among themselves as to the policy to be pursued with regard to the Philippines; but in the latter part of October they received definite instructions from the Secretary of State, Mr. John Hay, that the cession of Luzon alone could not be justified "on political, commercial, or humanitarian grounds," and that the entire archipelago must be surrendered by Spain. The Spanish commissioners protested vigorously against this demand, on the theory that it was outside of the terms of the peace protocol, but they were forced to yield, receiving as a sort of consolation prize the payment of twenty million dollars in compensation for the loss.
The final treaty, as signed on December 10, 1898, embodied the following terms: the independence of Cuba, the cession of Porto Rico, Guam, and the Philippines to the United States, the cancellation of the claims of the citizens of the two countries against each other, the United States undertaking to settle the claims of its citizens against Spain, the payment of twenty million dollars for the Philippines by the United States, and the determination of the civil and political status of the inhabitants of the ceded territories by Congress.
When the treaty of peace was published, the contest over the retention of the Philippines took on new bitterness—at least in public speeches and editorials. The contentions on both sides were so vehement that it was almost impossible to secure any frank discussion of the main issue: "Does the United States want a foothold in the Pacific in order to secure the trade of the Philippines and afford American capital an opportunity to develop the dormant natural resources, and in order also to have a station from which to give American trade and capital a better chance in the awakening Orient?" Democrats demanded self-government for the Philippines, "in recognition of the principles of the immortal Declaration of Independence." Republicans talked in lofty strains about "the mysterious hand of Providence which laid this burden upon the Anglo-Saxon race."
The proposal to retain the Philippines, in fact, gave the southern statesmen just the opportunity they had long wanted to taunt the Republicans with insincerity on the race question. "Republican leaders," said Senator Tillman, "do not longer dare to call into question the justice or necessity of limiting negro suffrage in the South." And on another occasion he exclaimed in querulous accents: "I want to call your attention to the remarkable change that has come over the spirit of the dream of the Republicans. Your slogans of the past—brotherhood of man and fatherhood of God—have gone glimmering down through the ages. The brotherhood of man exists no longer." To such assertions, Republicans of the old school, like Senator Hoar, opposed to imperialism, replied sadly, "The statements of Mr. Tillman have never been challenged and never can be." But Republicans of the new school, unvexed by charges of inconsistency, replied that high talk about the rights of man and of self-government came with poor grace from southern Democrats who had disfranchised millions of negroes that were just as capable of self-government as the bulk of the natives in the Philippines.
Senator Vest, on December 6, introduced in the Senate a resolution to the effect "that under the Constitution of the United States, no power is given to the Federal Government to acquire territory to be held and governed permanently as colonies." He was ably supported by Senator Hoar, from Massachusetts, who took his stand upon the proposition that "governments derive their just powers from the consent of the governed." On the other side, Senator O. H. Platt, of Connecticut, expounded the gospel of manifest destiny: "Every expansion of our territory has been in accordance with the irresistible law of growth. We could no more resist the successive expansions by which we have grown to be the strongest nation on earth than a tree can resist its growth. The history of territorial expansion is the history of our nation's progress and glory. It is a matter to be proud of, not to lament. We should rejoice that Providence has given us the opportunity to extend our influence, our institutions, and our civilization into regions hitherto closed to us, rather than contrive how we can thwart its designs."
At length on February 6, 1899, the treaty was ratified by the Senate, but it must not be assumed that all of the Senators who voted for the ratification of the treaty favored embarking upon a policy of "imperialism." Indeed, at the time of the approval of the treaty, a resolution was passed by the Senate to the effect that the policy to be adopted in the Philippines was still an open question; but the outbreak of an insurrection there led to an immediate employment of military rule in the Islands and criticism was silenced by the cry that our national honor was at stake.
