The new Spanish Government listened to American demands and made large promises of amelioration of conditions in Cuba. General Blanco was substituted for General Weyler, whose cruelty had made him known in the American press as "the Butcher"; it was announced that the reconcentrado camps would be broken up; and the Queen Regent decreed the legislative autonomy of Cuba. Arrangements had been made for the handling of minor disputes directly with the Governor-General of Cuba through the American Consul General at Havana, General Fitzhugh Lee. On December 6, 1897, McKinley, in his annual message to Congress, counseled patience. Convinced of the good intentions of the new Spanish Government, he sought to induce American public sentiment to allow it time to act. He continued nevertheless to urge upon Spain the fact that in order to be effective action must be prompt. Public sentiment against Spain grew every day stronger in the United States and was given startling impulse in February, 1898, by two of those critical incidents which are almost sure to occur when general causes are potent enough to produce a white heat of popular feeling. The Spanish Minister in the United States, Senor Dupuy de Lome, had aroused the suspicion, during his summer residence on the north shore of Massachusetts Bay, that he was collecting information which would be useful to a Spanish fleet operating on that coast. Whether this charge was true or not, at any rate he wrote a letter to a friend, a Madrid editor visiting Havana, in which he characterized McKinley as a vacillating and timeserving politician. Alert American newspaper men, who practically constituted a secret service of some efficiency, managed to obtain the letter. On February 9, 1898, De Lome saw a facsimile of this letter printed in a newspaper and at once cabled his resignation. In immediately accepting De Lome's resignation Spain anticipated an American demand for his recall and thus saved Spanish pride, though undoubtedly at the expense of additional irritation in the United States, where it was thought that he should have been punished instead of being allowed to slip away. Infinitely more serious than this diplomatic faux pas was the disaster which befell the United States battleship Maine: On January 24, 1898, the Government had announced its intention of sending a warship on a friendly visit to Havana; with the desire of impressing the local Cuban authorities with the imminence of American power. Not less important was the purpose of affording protection to American citizens endangered by the rioting of Spaniards, who were angry because they believed that Sagasta by his conciliatory policy was betraying the interests of Spain. Accordingly the Maine, commanded by Captain Sigsbee, was dispatched to Cuba and arrived on the 25th of January in the harbor of Havana. On the night of the 15th of February, an explosion utterly wrecked the vessel and killed 260 of the crew, besides wounding ninety.
