The succession of McKinley seemed likely to result in a change in the attitude of America toward the Cuban problem. He was more responsive to public opinion than his predecessor had been, public opinion was more and more coming to favor intervention, and his party had committed itself in its platform to Cuban independence through American action. Moreover, two events early in 1898 greatly irritated the United States.

On February 9 a New York newspaper published a letter written by Señor Enríque Dupuy de Lôme, Spanish minister to the United States, to a personal friend in Havana. It referred to President McKinley as a "would-be politician who tries to leave a door open behind himself while keeping on good terms with the jingoes of his party." It further revealed the intention of the Minister to carry on a propaganda among senators in the interest of a commercial treaty. On all sides it was seen that the usefulness of Señor de Lôme was at an end and his government immediately recalled him. On February 15 the whole world was shocked by the destruction of the United States battleship Maine in Havana harbor, with the loss of 260 officers and men. News of the disaster was accompanied by the appeal of Captain Sigsby, commander of the vessel, that popular judgment of the causes of the disaster be suspended until a court of inquiry could investigate and report. Nevertheless on March 9, Congress placed $50,000,000 at the President's disposal for the purposes of national defence and the navy prepared for a conflict that seemed inevitable. Both the Spanish and American authorities conducted examinations. The American court reported that the ship had been destroyed by the explosion of a submarine mine, which had caused the partial explosion of two or more of her magazines. No evidence could be found which would fix the responsibility on any individual. The Spanish court came to the conclusion that the catastrophe was due solely to an explosion of the ship's magazines. American opinion naturally supported the findings of the American court, and feeling ran high; newspapers demanded war; "Remember the Maine" summarized much of popular discussion.[4]

Under such circumstances, diplomatic negotiations looking toward peace were difficult, and resulted only in disagreements and delay. Accordingly on April 11 the President laid before Congress a succinct account of Cuban affairs and earnestly called for forcible intervention. The grounds for this action he found in the sufferings of the people of Cuba, the injuries to Americans and to American property and trade, and the menace to American peace which was entailed by continuous conflict at our very threshold.[5] The transfer of the Cuban question from the hands of the President to those of Congress was equivalent to a decision in favor of war. On April 19 the Senate and House resolved that the people of Cuba were and ought to be independent, demanded that Spain withdraw from the island and directed the President to use the force of the nation to achieve the results desired. The approval of the Executive on the following day completed the severance of peaceful relations with Spain. At daylight on April 22 Admiral Sampson and his fleet were crossing the narrows between Florida and Cuba, on the way to establish a blockade of the greater part of the island. Within three days more, Commodore George Dewey, who was in command of a fleet at Hong-Kong, had been instructed to proceed at once to the Philippine Islands and capture or destroy the Spanish fleet there. On April 25 Congress formally declared war upon the kingdom of Spain.

It was not by mere chance, of course, that Admiral Sampson and Commodore Dewey were prepared to act with such celerity. Authorities in the Navy Department had long felt that a collision with Spain was inevitable and had been preparing for such an eventuality. With as little publicity as possible the Department completed and commissioned ships that were already under construction; it hastened the repair of vessels which were in any way defective; it ordered target practice and fleet manoeuvres; and it prepared plans for the conduct of a naval war. Commanders of squadrons were instructed to keep in service men whose terms of enlistment were about to expire; supplies of ammunition were procured and shipped to points where they would be needed; the Oregon, which had been stationed on the Pacific coast, was ordered to return to Key West by way of the Straits of Magellan and so began a voyage whose closing days were watched with interest by a whole nation. A Northern Patrol Squadron was organized to guard New England; a Flying Squadron was assembled at Hampton Roads for service on the Atlantic coast or abroad; and a formidable array gathered at Key West under Rear-Admiral Sampson for duty in the West Indies. Foreign shipyards were scoured for vessels in process of building and several were purchased, completed and renamed for American service. Greater additions were made through the purchase of merchantmen and their transformation into auxiliary cruisers, gunboats and colliers. In these ways the attempt was made, with some success, to improvise a navy on the eve of war.

The people of the country had scarcely become accustomed to the thought that war with Spain had actually come to pass when word was received in Washington of the exploit of Commodore Dewey in the Philippine Islands. Attention for the moment was focussed on the Far East, and the press dilated upon the first test of the new American Navy.

The story of the test proved to have points of interest and importance. When Commodore Dewey received the orders already mentioned, on April 25, he finished immediately the preparations for conflict which had been initiated and turned his flagship, the Olympia, in the direction of Manila. His available force consisted of four protected cruisers, two gunboats, a revenue cutter, a collier and a supply ship. The city of Manila is on Manila Bay, a body of water twenty miles or more wide, and is reached only through a narrow entrance. Dewey judged that the channel was too deep to be mined successfully except by trained experts and that both contact and electrical mines would deteriorate so rapidly in tropical waters as to be effective only for a short time. He therefore decided to steam through the channel at night, disregarding the mines, and to attack the Spanish fleet which lay within. The plans worked out even better than he had hoped. With all lights masked and the crews at the guns, the squadron moved silently through the passage with no other opposition than three shots from a single battery. Once within the Bay Dewey steamed slowly toward the city of Manila and then back to a fortified point, Cavite, where he found his quarry arranged in an irregular crescent and awaiting the conflict. Oblivious of the hasty and inaccurate fire from the batteries on shore, he deliberately moved to a position within two and a half miles of the Spanish ships and said to the Captain of the Olympia, "You may fire when you are ready, Gridley."

Three times westward and twice eastward the American squadron ran slowly back and forth, using the port and starboard batteries in turn, and in a short time the shore batteries and the Spanish fleet were masses of ruins. Of the American forces, only eight were injured, and they only slightly, while 167 of the Spanish were killed and 214 wounded. News of the victory was as unexpected as it was welcome in the United States. President McKinley appointed Dewey an acting Rear-Admiral and on all sides discussion began of the situation and possibilities of the Philippines.

In the meantime, the position of the American squadron was far from secure. To be sure, all resistance from the batteries in and around Manila was quickly suppressed by a threat to destroy the city; nevertheless Admiral Dewey was in command of too slight a force to enable him to occupy both the town and its environs. He accordingly notified Washington that more troops were necessary if it were intended to seize and retain Manila, and expeditionary forces were despatched, the first of which arrived on June 30. Indeed it was high time that assistance be forthcoming, for new possibilities of conflict had appeared in the presence of a powerful force of German warships.

As soon as the defeat of the Spanish squadron had been effected, Admiral Dewey established a blockade of Manila Bay and, according to custom, the war vessels of interested nations went thither to observe the effectiveness of the blockade and to care for the well-being of their nationals. Among the early arrivals were the British, the French and the Japanese, all of whom observed the formalities of the situation and reported to the American Admiral before venturing into the harbor. The Germans, however, omitted the proprieties until sharply reminded by a shot across the bow of the Cormoran. By mid-June five German men-of-war under command of Vice Admiral von Diedrichs were in the Bay—a force nearly if not quite the match of the American squadron. When the Germans continued their disregard of the regulations controlling the blockade, indicating a potential if not an actual hostility, it became necessary for Admiral Dewey to have done with the Teutonic peril at once. He sent a verbal message to von Diedrichs which effectually ended all controversy. Admiral Dewey has not disclosed the exact phraseology of the message, nor did he send a record of it to the Navy Department. A newspaper correspondent who was acting as one of the Admiral's aides asserted that the protest was against von Diedrich's disregard of the usual courtesies of naval intercourse and that it closed with the words, "if he wants a fight he can have it right now." The disclosure by Captain Edward Chichester, in command of the English force, that he had orders to comply with Admiral Dewey's restrictions and that his sympathies were with the Americans, together with the arrival of the expeditionary force, assured American supremacy and a peaceful blockade. On August 13 a joint movement of the naval forces and the infantry under General Wesley Merritt resulted in the speedy surrender of the city of Manila. The Americans were now in control of the capital of the Philippine Islands and would, perforce, face the question of the ultimate disposition of the archipelago in case of the eventual defeat of Spain. In the meanwhile, popular attention turned toward stirring events which were taking place in the Caribbean Sea.
