USS Oklahoma Sailor Killed During World War II Accounted For (Mason, H.)

By DPAA Public Affairs

WASHINGTON – Navy Musician 1st Class Henri C. Mason, killed during the attack on the USS Oklahoma in World War II, was accounted for on March 26, 2018.

On Dec. 7, 1941, Mason was assigned to the battleship USS Oklahoma, which was moored at Ford Island, Pearl Harbor, when the ship was attacked by Japanese aircraft. The USS Oklahoma sustained multiple torpedo hits, which caused it to quickly capsize. The attack on the ship resulted in the deaths of 429 crewmen, including Mason.

In 2015, DPAA disinterred remains from the National Memorial Cemetery of the Pacific, known as the Punchbowl, in Honolulu.

DPAA is grateful to the Department of Veterans Affairs for their partnership in this mission.

Interment services are pending; more details will be released 7-10 days prior to scheduled funeral services.

Mason's name is recorded on the Courts of the Missing at the Punchbowl, along with the others who are missing from World War II. A rosette will be placed next to his name to indicate he has been accounted for.

Press Release | Dec. 3, 2018

USS Oklahoma Sailor Accounted For From World War II (Mason, C.)

WASHINGTON – The Defense POW/MIA Accounting Agency (DPAA) announced today that the remains of a U.S. serviceman, accounted for from World War II, are those of Navy Reserve Musician 1st Class Henri C. Mason, 48, of Corwith, Iowa. Mason was accounted for on March 26, 2018.

On Dec. 7, 1941, Mason was assigned to the battleship USS Oklahoma, which was moored at Ford Island, Pearl Harbor, when the ship was attacked by Japanese aircraft. The USS Oklahoma sustained multiple torpedo hits, which caused it to quickly capsize. The attack on the ship resulted in the deaths of 429 crewmen, including Mason.

From December 1941 to June 1944, Navy personnel recovered the remains of the deceased crew, which were subsequently interred in the Halawa and Nu’uanu Cemeteries.

In September 1947, tasked with recovering and identifying fallen U.S. personnel in the Pacific Theater, members of the American Graves Registration Service (AGRS) disinterred the remains of U.S. casualties from the two cemeteries and transferred them to the Central Identification Laboratory at Schofield Barracks. The laboratory staff was only able to confirm the identifications of 35 men from the USS Oklahoma at that time. The AGRS subsequently buried the unidentified remains in 46 plots at the National Memorial Cemetery of the Pacific (NMCP), known as the Punchbowl, in Honolulu. In October 1949, a military board classified those who could not be identified as non-recoverable, including Mason.

In April 2015, the Deputy Secretary of Defense issued a policy memorandum directing the disinterment of unknowns associated with the USS Oklahoma. On June 15, 2015, DPAA personnel began exhuming the remains from the Punchbowl for analysis.

To identify Mason’s remains, scientists from DPAA and the Armed Forces Medical Examiner System used mitochondrial DNA (mtDNA) analysis, anthropological and dental analysis, as well as circumstantial and material evidence.

DPAA is grateful to the Department of Veterans Affairs for their partnership in this recovery.

Of the 16 million Americans who served in World War II, more than 400,000 died during the war. Currently there are 72,772 (approximately 26,000 are assessed as possibly-recoverable) still unaccounted for from World War II. Mason’s name is recorded on the Walls of the Missing at the Punchbowl, along with the others missing from WWII. A rosette will be placed next to his name to indicate he has been accounted for.

For family contact information, contact the Navy Casualty Office at (800) 443-9298.

Mason will be buried May 28, 2019, in Honolulu, Hawaii.
