The United States declared war against Spain, April 21, 1898, to free Cuba, and at once arranged an understanding with the Cuban revolutionists looking to co-operation between their forces and ours to that end. For some years prior to this, political conditions in the Philippines had been quite similar to those in Cuba, so that when, two days after war broke out, the Honorable Spencer Pratt, Consul-General of the United States at Singapore, in the British Straits Settlements, found Aguinaldo, who had headed the last organized outbreak against Spain in the Philippines, temporarily sojourning as a political refugee at Singapore, in the Filipino colony there, he naturally sought to arrange for his co-operating with us against Spain, as Gomez and Garcia were doing in Cuba. Thereby hangs the story of "Mr. Pratt's Serenade." However, before we listen to the band whose strains spoke the gratitude of the Filipinos to Mr. Pratt for having introduced Aguinaldo to Dewey, let us learn somewhat of Aguinaldo's antecedents, as related to the purposes of the introduction. The first low rumbling of official thunder premonitory to the war with Spain was heard in Mr. McKinley's annual message to Congress of December, 1897, [2] wherein he said, among other things: The most important problem with which this government is now called upon to deal pertaining to its foreign relations concerns its duty toward Spain and the Cuban insurrection. In that very month of December, 1897, Aguinaldo was heading a formidable insurrection against Spanish tyranny in the Philippines, and the Filipinos and their revolutionary committees everywhere were watching with eager interest the course of "The Great North American Republic," as they were wont to term our government.
