Playing career

As a youth, Ingram attended Jeffersonville High School and Culver Military Academy in Culver, Indiana, then was appointed to the United States Naval Academy in 1903, at the age of 17. During Ingram's time at the academy, he was a member of the school's rowing, track and football teams, leading the latter team to the Midshipmen's first victory in six years over their bitter rivals from Army by scoring the lone touchdown in the 1906 clash. His athletic exploits helped earn him the academy's prestigious Athletic Sword and induction into the College Football Hall of Fame in 1968.

Coaching career

As a lieutenant, Ingram was named the 15th head football coach of the United States Naval Academy and he held that position for two seasons, from 1915 until 1916, compiling a record of 9–8–2.^[1]

World War I and interwar years

During World War I, Ingram was awarded the Navy Cross for his services on the staff of Rear Admiral Hugh Rodman, Commander, Division Nine, Battle Force, Atlantic Fleet.^[2]

Earning the rank of commander in 1924, Ingram became the commanding officer of the destroyer USS Stoddert (DD-302) before returning to the United States Naval Academy to serve as both athletic director and football director from 1926 to 1930.

Ingram moved on to command the battleship USS Pennsylvania (BB-38) for a period of time after that, before serving as Officer-in-Charge of the Public Relations Branch.

Prior to his promotion to captain in 1935, Ingram served as an aide to the Secretary of the Navy, then returned to the sea as commander of Destroyer Squadron Six. Ashore, he was Captain of the Yard, New York Navy Yard in Brooklyn, New York before returning to sea, in command of the battleship USS Tennessee (BB-43).

World War II

In the early years of World War II, Ingram was promoted to rear admiral on January 10, 1941, and served as Commander Task Force Three prior to his designation in September 1942 as Commander South Atlantic Force, United States Atlantic Fleet, with the rank of vice admiral. This force, with headquarters in Brazil, guarded shipping in the coastal waters south of the Equator and throughout the United States zone of responsibility in the South Atlantic. Ingram's command included air and surface units of Brazil which were brought to a high state of efficiency through his leadership and coordinating efforts. The ability to develop and maintain harmony and close cooperation with Brazilian naval forces contributed to the control of the South Atlantic achieved by the Allies. He assumed personal responsibility for properly equipping and training the Brazilian Navy and for their combat operations against U-Boats and German raiders and later for the important task of maintaining the air and sea rescue patrol for ultimate deployment in the Pacific. For his services in these important commands, he was awarded the Navy Distinguished Service Medal and a gold award star in lieu of a second award.

On November 15, 1944, Ingram was appointed Commander-in-Chief, United States Atlantic Fleet, with the rank of admiral. In this command he played a major role in assuring the steady flow of troops and materials to Europe across the Atlantic during the later phases of World War II. He also directed Atlantic Fleet efforts in containing and destroying the German U-Boat fleet. For exceptionally meritorious service during his command, he was awarded a gold award star in lieu of a third Distinguished Service Medal.
