On December 13, 1944 embarks 1,589 American Prisoners Of War (POWs) including roughly 1,100 officers and 30 Allied POWs from Canabanatuan POW Camp and Bilibid POW Camp that were detained in the cargo holds. With prisoners detained the cargo holds Oryoku Maru was dubbed a "Hell Ship" for the prisoners. Also embarked are 1,500 Japanese Army solider, 547 Japanese women and children and 1,127 passengers and crew from other Japanese vessels plus the ashes of 728 Japanese war dead plus cargo including a Packard car owned by General MacArthur.

By 6:50am roughly 7 miles off Napo Point spotted by U.S. Navy (USN) carrier planes from USS Hornet (CV-12) and the three ships are attacked eleven times. During the attacks, Oryoku Maru is hit by a bomb and near misses that cause leaks and develops a 15° list to port. Aboard, hundreds of prisoners were killed. Damaged, the captain orders her beached in shallow water off Suesute Point. Emergency repairs are made to the engine room and refloated at high tide and at 9:50pm arrives in Subic Bay arriving at 9:50pm.
