Born in 1811 in Maine, Henry Prince graduated from the USMA in 1835 and served with the 4th Infantry for most of his military career. He was wounded twice, once during the Seminole Wars in Florida and again, severely, in Mexico at Molino del Ray.
Captain Prince commanded troops of Company C, 4th Infantry at Ft. Steilacoom; he also served on the Coast Survey expeditions of Puget Sound from 1850-55.
He served as an Army Paymaster for the remainder of the 1850s, participating in the Utah/Mormon Expedition, and as a division commander during the Civil War. He was captured at the Battle of Cedar Mountain but resumed his command duties upon parole a few months later.
He left volunteer service in 1866 and continued as a paymaster after the war, returning to the Pacific Coast in 1875. General Prince retired in 1879 as Chief Paymaster.
