The other Utah troops to see action were the black units, the 24th Infantry Regiment and the 9th Cavalry Regiment, who were engaged at San Juan Hill in the fight for Santiago, Cuba. These troops left Fort Douglas, Utah, on 20 April and returned to Fort Douglas on 2 September 1898. They were noted for their heroic attack up San Juan Hill and for their humane nursing of yellow fever patients at Siboney Hospital in Cuba. The 24th and 9th regiments returned to Fort Douglas after the Cuban campaign; however, in 1899 members of these units were reassigned to other posts in the United States. The leadership of their commander, General J. Ford Kent, was highly praised during the war.

The other units from Utah did not get opportunity to prove their gallantry in war. Troop I of Torrey's Roughriders, led by Utah Adjutant General John Q. Cannon, spent the period from 11 May to 24 October 1898 in federal service, most of the time in camp at Panama Park, Jacksonville, Florida. They suffered from the heat and many became sick with malaria and dysentery; some from the regiment died. The First Troop of Utah Cavalry, under the command of Captain Joseph E. Caine, did guard duty in Yosemite, Sequoia, and General Grant parks in California. Their duty was to patrol the parks to insure that these areas were protected from any threats from herdsmen of Spanish descent who tended sheep and cattle there. Artillery Battery C assumed post duties on Angel Island in San Francisco Bay; and Company K of Engineers spent the war near Diamond Head Mountain on Oahu, Hawaii, constructing permanent military barracks.
