Biography.
Ennis was born in the Presidio of San Francisco on January 30, 1878, though he spent much of his early life in Newport, Rhode Island. His father, William Ennis, was a veteran of the American Civil War and Spanish–American War who attained the rank of brigadier general and from 1933 to 1938 was the oldest living graduate of the United States Military Academy at West Point. Ennis graduated from West Point in 1901 and was commissioned in the Artillery Corps.
Ennis served at Fort Hamilton from 1901 to 1904, West Point from 1904 to 1908, and at Fort Reno from 1908 to 1911. He was considered one of the best trainers of artillery horses in the country. Ennis went to the Philippines in 1912 with the First Battalion of the First Field Artillery, though he and the others rejoined the rest of the regiment in 1913. He returned to West Point in 1915 in order to command his artillery detachment. In late 1917, Ennis went to Fort Sill in order to serve as a senior instructor in the Department of Materiel of the School of Fire. He was promoted to colonel in May 1918 and served as the director of the Department of Materiel, for which he received the Army Distinguished Service Medal, the citation for which reads:

As Director of the Department of Material, School of Fire, for Field Artillery at Fort Sill, Oklahoma, from 9 May 1918 to 30 August 1918, General Ennis' untiring energy, devotion to duty, and exceptional qualifications for the task he had to perform, were directly responsible for the splendid organization developed.
