He was then transferred to the 5th Cavalry Regiment, serving as a recruiting officer at Brooklyn where he would meet Isabel Bowie and they got married on 28 June, 1871, and she'd accompany him across the western frontier. Between 1872 and 1874, Hamilton served under Major General George Crook during the Apache Wars, earning a citation of "conspicuous services and gallantry" for his service on February and March 1873. He'd later take part a punitive expedition against Dull Knife's forces after the Battle of the Little Bighorn. He'd also take part in the Bannock War and the Ute Wars from 1879 to 1880. Hamilton also became a naturalized American citizen by 1882 and moved to Fort Robinson with his family. They'd later move to Fort Riley by the end of the 1880s and Hamilton was promoted to Major in 1887. He was then transferred to the 1st Cavalry Regiment and served at Fort Custer and Fort Assinniboine and would participate in the Ghost Dance War. During the early 1890s, Hamilton served as the Acting Inspector General in the Departments of the Columbia and the Platte but shortly after, returned to the 1st Cavalry Regiment at Fort Sill in 1895. He also received his promotion to Lieutenant Colonel on 1897 while within the 9th Cavalry Regiment at Fort Robinson where he'd encounter Frederic Remington and Hamilton would be featured in Remington's work The Essentials of Fort Adobe. Spanish-American War
Tensions with Spain began to increase due to the ongoing Cuban War of Independence and the 9th Cavalry Regiment began making movements south for Chattanooga, Tennessee and Tampa, Florida to prepare for an intervention in Cuba. After its previous colonel fell to illness, Hamilton assumed command of the regiment as the boarded the SS Miami as he penned his final letter to his wife while aboard the ship, On 1 July, 1898, the 9th Cavalry along with the 6th Cavalry Regiment, the 10th Cavalry Regiment and the Rough Riders made up the main skirmish line of the Battle of San Juan Hill. During the battle, Hamilton waved his hat and encouraged his troops to overrun the Spanish positions upon the top of the hill but while directing his troops, Hamilton was shot in the throat, instantly killing him.
