Retired Army Col. Charles Ennis, 84, a combat veteran of World War I who had lived in Northern Virginia for the past five years, died Sunday at the Fairfax Nursing Center in Fairfax following a stroke.

He received his Army commission in 1917, and served with the 2nd Infantry "Indian Head" division at the battles at Chateau Thierry and Belleau Wood. He was awarded the French Croix de Guerre.

Following the war, Col. Ennis was a member of American occupation forces along the Rhine in Germany. During World War II, he worked at the old War Department and later served on Gen. Douglas MacArthur's staff in the Far East.

After World War II, he again was assigned to Washington where he worked in the National Guard Bureau before retiring from active duty in 1953.

Col. Ennis retired to his native Lyons, N.Y., and was a court crier. He belonged to the Sons of the American Revolution, the American Legion, and the Veterans of Foreign Wars.

He was a graduate of Cornell University.

Survivors include a son, retired Air Force Col. Robert B. Ennis, and a daughter, Sarah E. Macklin, both of Alexandria; six grandchildren; and one great-grandchild.

The family suggests that expressions of sympathy be in the form of contributions to the First Presbyterian Church in Lyons, N.Y. 14489.
