Early life

He was born Clement Alexander Finley Flagler in Augusta, Georgia, the son of Brigadier General Daniel Webster Flagler, for whom Fort Flagler, Washington was named.

The younger Flagler was named for his maternal grandfather, Army Surgeon General Clement Alexander Finley. Known as Clement Flagler, Clement A.F. Flagler, and C.A.F Flagler, he grew up in Iowa while his father commanded the Rock Island Arsenal.

In 1885 he received a bachelor of science degree from Griswold College. He then accepted appointment to the United States Military Academy (USMA) at West Point, New York, after being recommended by Congressman Jerry Murphy. He graduated in 1889, and Flagler's high class ranking (3 of 29) enabled him to obtain a sought after position in the Army's Engineer branch. Among his fellow graduates included several men who would become general officers, such as Charles Dudley Rhodes, William S. Graves, Eben Eveleth Winslow, Frank Daniel Webster, Walter Augustus Bethel, Winthrop S. Wood, Chester Harding, William L. Kenly, Joseph D. Leitch, Edward McGlachlin Jr., George LeRoy Irwin, William Wright Harts, William G. Haan, Charles Crawford and William Lassiter. Charles Young was another distinguished graduate, becoming the first African American to attain the rank of colonel.

While at West Point Flagler was nicknamed "Sioux" as a testament to his dark eyes, hair, and complexion, his having been raised in Iowa, and his self-professed Native American heritage, and his classmates used it with him for the rest of his life.

Pancho Villa Expedition

During Mexican border skirmishes of 1914–1916, Flagler served on General Funston's staff in the Vera Cruz Expedition.

World War I

Shortly after the American entry into World War I, in April 1917, Flagler was, on May 15, promoted to the rank of colonel. Two months later, when a new regiment of engineers, the 7th, was being raised, he was assigned to command the new regiment. In December of that year the 7th Engineers was assigned to the 5th Division, then in its early stages of creation and commanded by Major General John E. McMahon. Flagler left his regiment soon afterwards, to take command of the 5th Field Artillery Brigade, also part of the 5th Division, and having under its command the 19th, 20th, and 21st Field Artillery Regiments. At the time the brigade was stationed at Camp Stanley, Leon Springs, Texas.
