Retired Col. Thomas Du Val Roberts, 74, who served 30 years the Army, died last Thursday in Watsonville Community Hospital, Watsonville, Calif., after a short illness.

Born in Texas. Col. Roberts was the son of Brig. Gen. Charles D. Roberts, who was chief of staff for the 81st Division in World War II. Col. Roberts graduated from West Point in 1924, and joined a cavalry unit in Kansas. He served in the South Pacific during World War II, where he was deputy chief of staff in the U.S. Armed Forces in the South Pacific under Gen. M.F. Harmon.

In January, 1944, he was transferred to the operations section of the War Department in Washington.

Two years later, he was transferred to Tokyo with the occupation forces of the 1st Cavalry Division.

Col. Roberts returned to the United States in 1948, and began teaching armored warfare tactics at Ft. Knox, Ky. That assignment ended in 1952, when he was transferred to the U.S. command in West Germany.

He retired from active duty in 1954, and moved to Washington to live with his father. He lived here for 12 years and moved to California when his father died in 1966.

Col. Roberts, a recipient of the Distinguished Service Medal and the Legion of Merit, is survived by his wife, Rosalie, of the home in California, and two daughters.
