The remains of two sailors killed at Pearl Harbor during the Japanese attack on the Pacific Fleet in 1941 on the battleship USS Oklahoma have been identified and will be returned for burial, according to the Defense POW/MIA Accounting Agency.

They are Seaman 2nd Class Lewis L. Wagoner, 20, of Douglass County, Mo., who will be buried Oct 8 in Whitewater, Kan.; and Lt. j.g. Aloysius H. Schmitt, 32, of St. Louis. Mo., who be buried Oct. 8 in Dubuque, Iowa.

Both sailors were assigned to the Oklahoma on Dec. 7, 1941, which was moored at Ford Island when it was attacked by Japanese aircraft.

The battleship was hit by seven to nine Japanese torpedoes and rolled in the harbor, trapping hundreds of men inside, according to the National Park Service.

They were buried in 46 plots at the National Memorial Cemetery of the Pacific in unmarked grave sites after military officials were only able to identify 35 men in 1947.

The attack on the ship resulted in 429 casualties.

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 Punchbowl for analysis.

The Pentagon news release said to identify Schmitt’s remains, scientists used mitochondrial DNA analysis, which matched a grandnephew; as well as circumstantial evidence and laboratory analysis, to include dental comparisons, which matched Schmitt’s records.

Scientists used the same tests to identify Wagoner’s remains, matching two brothers as well as his records.

In 2015, the last of the remaining sailors and Marines from the Oklahoma were disinterred and identifications continue to be made.
