Philippine-American War
Philippine-American War Hostilities broke out on February 4, 1899, after two American privates on patrol killed three Filipino soldiers in San Juan, a Manila suburb. This incident sparked the Philippine-American War, which would cost far more money and take far more lives than the Spanish-American War. Some 126,000 American soldiers would be committed to the conflict; 4,234 Americans died, as did 12,000-20,000 Philippine Republican Army soldiers who were part of a nationwide guerrilla movement of indeterminate numbers.
The general population, caught between Americans and rebels, suffered significantly. At least 200,000 Filipino civilians lost their lives as an indirect result of the war mostly as a result of the cholera epidemic at the war's end that took between 150,000 and 200,000 lives. Atrocities were committed by both sides.
The poorly equipped Filipino troops were easily overpowered by American troops in open combat, but they were formidable opponents in guerrilla warfare. Malolos, the revolutionary capital, was captured on March 31, 1899. Aguinaldo and his government escaped, however, establishing a new capital at San Isidro, Nueva Ecija. On June 5, 1899, Antonio Luna, Aguinaldo's most capable military commander, was killed by Aguinaldo's guards in an apparent assassination while visiting Cabanatuan, Nueva Ecija to meet with Aguinaldo. With his best commander dead and his troops suffering continued defeats as American forces pushed into northern Luzon, Aguinaldo dissolved the regular army on November 13 and ordered the establishment of decentralized guerrilla commands in each of several military zones. Another key general, Gregorio del Pilar, was killed on December 2, 1899 in the Battle of Tirad Pass�a rear guard action to delay the Americans while Aguinaldo made good his escape through the mountains.
Aguinaldo was captured at Palanan, Isabela on March 23, 1901 and was brought to Manila. Convinced of the futility of further resistance, he swore allegiance to the United States and issued a proclamation calling on his compatriots to lay down their arms, officially bringing an end to the war. However, sporadic insurgent resistance continued in various parts of the Philippines, especially in the Muslim south, until 1913.
In 1900, President McKinley sent the Taft Commission, to the Philippines, with a mandate to legislate laws and re-engineer the political system. On July 1, 1901, William Howard Taft, the head of the commission, was inaugurated as Civil Governor, with limited executive powers. The authority of the Military Governor was continued in those areas where the insurrection persisted. The Taft Commission passed laws to set up the fundamentals of the new government, including a judicial system, civil service, and local government. A Philippine Constabulary was organized to deal with the remnants of the insurgent movement and gradually assume the responsibilities of the United States Army.
