WASHINGTON –
The Defense POW/MIA Accounting Agency announced today that U.S. Army Pvt. Harland J. Hennessey, 24, of Boonville, New York, who was captured and died as a prisoner of war during World War II, was accounted for Sept. 23, 2024.
Hennessey's family recently received their full briefing on his identification, therefore, additional details on his identification can be shared.
In late 1941, Hennessey was a member of the 803rd Engineer Battalion, Aviation, when Japanese forces invaded the Philippine Islands in December. Intense fighting continued until the surrender of the Bataan peninsula on April 9, 1942, and of Corregidor Island on May 6, 1942.
Thousands of U.S. and Filipino service members were captured and interned at POW camps. Hennessey was among those reported captured when U.S. forces in Bataan surrendered to the Japanese. They were subjected to the 65-mile Bataan Death March and then held at the Cabanatuan POW Camp #1. More than 2,500 POWs perished in this camp during the war.
According to prison camp and other historical records, Hennessey died Nov. 1, 1942, and was buried along with other deceased prisoners in the local Cabanatuan Camp Cemetery in Common Grave 704.
Following the war, American Graves Registration Service (AGRS) personnel exhumed those buried at the Cabanatuan cemetery and relocated the remains to a temporary U.S. military mausoleum near Manila. In 1947, the AGRS examined the remains in an attempt to identify them. Two of the sets of remains from Common Grave 704 were identified, while the remaining eight were declared unidentifiable. The unidentified remains were buried at the Manila American Cemetery and Memorial (MACM) as Unknowns.
In 2018, as part of the Cabanatuan Project, DPAA exhumed the remains associated with Common Grave 704 and sent them to the DPAA laboratory for analysis.
To identify Hennessey’s remains, scientists from DPAA used dental and anthropological analysis, as well as circumstantial evidence. Additionally, scientists from the Armed Forces Medical Examiner System used mitochondrial DNA and mitochondrial genome sequence analysis.
Although interred as an Unknown in MACM, Hennessey’s grave was meticulously cared for over the past 70 years by the American Battle Monuments Commission (ABMC). Today, Hennessey is memorialized on the Walls of the Missing at the Manila American Cemetery and Memorial in the Philippines. A rosette will be placed next to his name to indicate he has been accounted for.
Hennessey will be buried in Boonville, New York, in July 2025.

DPAA is grateful to the ABMC and the United States Army for their partnership in this mission.
