WORLD WAR II
UNITED STATES ARMY
Unaccounted For

On December 13, 1944, Japanese forces in the Philippines began the transfer of 1,621 Allied prisoners of war (POWs) to Japan. The POWs were to make the journey aboard transport ships whose harsh conditions and extreme overcrowding led survivors to refer to them as "Hell Ships." The ships also lacked markings that would distinguish them from any other military target, causing some of them to be attacked by Allied forces who could not identify them as POW transports. On December 14, 1944, Allied aircraft attacked the first ship, the Oryoku Maru, in Subic Bay in the Philippines, killing many Allied POWs who became lost in the water, sank with the ship, or were washed ashore. Survivors of the bombing were put aboard two other ships, the Enoura Maru and the Brazil Maru, to continue on to Japan. During its journey on January 9, 1945, while anchored in Takao Harbor, Formosa (present-day Taiwan), the Enoura Maru was attacked by Allied aircraft from the USS Hornet (CV-8), killing Allied POWs who were lost in the water, on board the ship, or on the nearby shore. Survivors of the Enoura Maru bombing were loaded onto the Brazil Maru, and reached Japan on January 30, 1945. As a result of these incidents, Allied POWs were lost in the Philippines, at sea between the Philippines and Taiwan, while anchored in Taiwan, at sea between Taiwan and Japan, and in Japan. The attacks on these POW transports ultimately resulted in a series of death notifications from the Japanese government through the International Red Cross (IRC), and some casualties were given up to five different dates of death at various locations during the transfer. Witness accounts from surviving POWs offer detailed information for a handful of casualties, but the specific dates of loss and/or last-known locations for many of these POWs are based on the most recent reported date of death.
Major Marvin A. Tannehill entered the U.S. Army from Utah and served with the Quartermaster Corps in the Philippines during World War II. He was taken as a POW following the Japanese invasion and was interned in the islands until December 1944, when he was transferred to the Oryoku Maru for transport to Japan. He survived the attack on the Oryoku Maru and was eventually transferred to the Brazil Maru. Records indicate that on January 28, 1945, MAJ Tannehill died of wounds he had suffered in the earlier attacks, and he was reportedly buried at sea. However, these records often involve information solely furnished by enemy governments, with some casualties given multiple dates of death. Future research may determine these reports were inaccurate. MAJ Tannehill’s remains could not be identified following the war, and he is still unaccounted-for. Today, Major Tannehill is memorialized on the Walls of the Missing at the Manila American Cemetery in the Philippines.
