During the Mexican War, he served with the 1st Dragoons and was captured and held for eight days as a prisoner of war while making a reconnaissance near Buena Vista, Mexico. After the war, he served in the West, was promoted to first lieutenant and captain, and took part in a number of Indian campaigns. During this time, Sturgis was sent to West Ely, Missouri, where he met Jerusha Wilcox. In 1851 they married and would have six children.[3]
Civil War
When the Civil War broke out, Sturgis continued to serve with the 1st Dragoons (which was shortly afterwards redesignated the 1st Cavalry Regiment). He was promoted to major in May 1861 and later transferred to the 4th Cavalry Regiment.[2] In August 1861, at the Battle of Wilson's Creek, he succeeded to command of the Federal forces after the death of Brig. Gen.Nathaniel Lyon. In March 1862 he was appointed brigadier general of volunteers to rank from August 10, 1861, the day of the battle, as well as breveted lieutenant colonel, Regular Army.[2]
After a tour of duty in the Washington, D.C., defenses, he was ordered to the front to support General John Pope's Army of Virginia just prior to the Second Battle of Bull Run. While attempting to secure priority from General Herman Haupt for movement of his troops on the railroad, he was told that he must wait his turn as other troops and supplies were going forward to support Pope. His reaction was his now-famous remark, "I don't care for John Pope one pinch of owl dung."
Sturgis was breveted brigadier general (for South Mountain) and major general (for Fredericksburg), Regular Army, in March 1865 and mustered out of the volunteer service in August. He reverted to his regular rank of lieutenant colonel of the 6th U.S. Cavalry. On May 6, 1869, he became colonel and commander of the 7th U.S. Cavalry and his lieutenant colonel was George Armstrong Custer.
Sturgis was on detached duty as the Superintendent of Mounted Recruiting Service and in command of the Cavalry Depot in St. Louis, Missouri,[2] when parts of the 7th Cavalry were destroyed at the Battle of Little Big Horn (one of Sturgis's sons, Second Lieutenant James G. Sturgis, was also an officer with the 7th and was killed in that battle.) Samuel Sturgis then took personal command of the regiment and led the 7th Cavalry in the campaign against the Nez Percé in 1877. Sturgis and his soldiers headed off the Nez Percé and waited to attack them once they emerged from their passage through the wilderness of Yellowstone Park. The Indians deceived Sturgis with a feint and eluded him, continuing their flight northward toward Canada. Sturgis soon caught up with the Nez Percé but at the Battle of Canyon Creek, the Indians, although outnumbered two to one, again escaped from his grasp.[4]
The city of Sturgis, South Dakota, is named for Samuel D. Sturgis.[7] A sculpture of him mounted on horseback is located at the eastern entrance of the town on South Dakota Highway 34 and 79.
