Following the explosion of the in Havana Harbor on February 15, 1898, war between the United States and Spain, which then ruled Cuba, seemed inevitable. Maj.
Arthur L. Wagner, head of the Military Information Division, successfully petitioned Adj. Gen.
Henry Clark Corbin for permission to send spies to Cuba and Puerto Rico to gather military information. Wagner selected forty-year-old 1st Lt. Andrew S. Rowan to join Gen.
Calixto García, commander of the rebel forces in eastern Cuba. Rowan, posing as a civilian, boarded a steamer in New York bound for Kingston, Jamaica. As a cover story, he carried papers designating him as a
military attaché bound for Santiago, Chile. (The inclusion of this cover story in official documents has understandably led some to believe, incorrectly, that it was true. In fact, Rowan never set foot in Chile.) With the help of the U.S. consul in Kingston, he connected with the Cuban Revolutionary Junta, some of whose members transported him by open boat during one of their trips to the southeastern coast of Cuba. They went ashore the morning of April 25. Following an eight-day horseback journey with rebels through the
Sierra Maestra Mountains, Rowan met with García in the city of
Bayamo on May 1. Rowan's assignment was to keep the War Department informed as to “the strength, efficiency, movements and general military situation.” His orders were to stay in Cuba, to “accompany the Insurgent Forces, and to send back dispatches.” Disregarding his orders, Rowan said he was there to gather information regarding García's needs in order for him to cooperate with the U.S. armed forces; he said also that he was eager to return to the U.S. García, seeing an opportunity, sent him back to the U.S. within hours of his arrival. Traveling with him were members of García's staff to confer with U.S. officials. After a five-day journey to Manatí Bay on Cuba's north coast they “drew a little cockle-shell of a boat from under a mangrove bush” and set sail for Florida. A passing sponging steamer carried them to Nassau, and from there they eventually sailed to Tampa, arriving on May 9. Rowan had no sooner landed in Cuba on April 25 than details of his secret mission were splashed across the pages of America's newspapers. It was learned that while in Jamaica Rowan had revealed this information to an
Associated Press correspondent named
Elmer Roberts. This was not what Adj. Gen. Corbin anticipated. Had the news reports not made Rowan a popular hero, however falsely, Corbin might have had him
court-martialed. Instead he was deemed as popular as
Buffalo Bill, lauded by Maj. Gen
Nelson A. Miles, commanding general of the army, and temporarily promoted to lieutenant-colonel in the 6th Regiment Volunteer Infantry. The United States declared war on Spain on April 25 and invaded Cuba on June 22. Less than two months later, Spain signed a protocol effectively ending the war. It officially ended with the signing of the
Treaty of Paris on December 10, 1898. On August 22, under orders from Miles, Rowan and another officer began a horseback inspection tour of Cuba that lasted six weeks and resulted in a highly detailed report. == Philippine War ==
