The service rendered by each of these units varied: some saw military action; others were stationed in areas of the United States and Hawaii. Batteries A and B, Utah Light Artillery, were mustered in on 9 May 1898 and proceeded to the Manila campaign in the Philippines. The officers appointed to lead these units were Captain Richard W. Young (a West Point graduate, former regular army artilleryman, and a son of Brigham Young), and Captain Frank Grant (who had served in the Utah National Guard as a colonel). In the Philippines, these units fought as the 2nd Brigade, 2nd Division. The American campaigns resulted in the capture of Manila and the surrender of the Spanish troops on 14 August 1898.
After the defeat of the Spanish troops, the war moved into the Philippine Insurrection phase, in which the Americans fought against the Filipinos who were trying to gain their independence. American troops, assisted by the Utah Artillery until 1899, continued to fight until the insurrectionists were defeated in 1901. Utah A and B batteries left the Philippines on 24 June 1899, having fought in more than one hundred engagements and suffering casualties of fifteen men killed by fighting or disease and fourteen others wounded.
