The Hellships Memorial Foundation (HMF), with support from the Cultural Heritage Agency of the Netherlands, investigated to determine the identity of a shipwreck located off the coast of La Paz, Zambales, in the Philippines. Following a comprehensive, multidisciplinary investigation, the investigation concluded with a high degree of confidence that the wreck is the Japanese cargo vessel Hofuku Maru.
Historical Context The Hofuku Maru was a 385-foot Dai-ichi Taifuku-class freighter. On September 21, 1944, while sailing as part of Japanese convoy MATA-27, it was attacked and sunk by United States Navy carrier aircraft from Task Group 38.2. Tragically, the Hofuku Maru was operating as a "Hellship" at the time, transporting over 1,250 Allied prisoners of war (POWs), predominantly from the United Kingdom and the Netherlands.
Key Evidence for Identification The HMF utilized a forensic convergence model that combined several independent lines of evidence to identify the wreck:
Archival and Cartographic Records: A critical breakthrough was the discovery of a Japanese after-action report from the convoy escort vessel CD-1 in the Japan Center for Asian Historical Records (JACAR). This report, along with U.S. Navy Aircraft Action Reports and aerial photographs from the USS Bunker Hill, placed the sinking location exactly where the La Paz wreck currently rests. Additionally, Japanese POW registration cards list the coordinates of the prisoners' deaths, which match the physical wreck site within just 175 meters.
Archaeological Marine Surveys: Using side-scan sonar, Remotely Operated Vehicles (ROVs), and diver observations, the HMF surveyed the site and found a steel cargo vessel whose dimensions (377 feet long, 51.85 feet wide) perfectly align with the Hofuku Maru's original blueprints.
Damage Signatures: The surveys revealed that the wreck is split into two principal sections with a massive gap amidships. This catastrophic damage signature perfectly matches historical accounts, U.S. strike reports, and war crimes trial testimonies describing a devastating torpedo and bomb strike that "broke the ship's back" and caused it to sink in roughly three to five minutes.
Oral Histories: Local fishermen have known about the wreck for decades and, notably, have always referred to it simply as "Maru".
Site Condition and Threats The wreck lies at a depth exceeding 50 meters and is subject to severe environmental and human threats. Since the 1991 eruption of Mount Pinatubo, heavy layers of volcanic silt have been burying the wreck, a process currently being accelerated by nearby river dredging operations. Furthermore, the site faces a "very high" threat level from illegal and destructive "dynamite fishing" practices, which have caused ongoing structural collapse.
Significance and Recommendations Because it represents the final resting place for hundreds of Allied POWs and Japanese crew members who perished during the attack, the Hofuku Maru wreck possesses profound historical and memorial significance. The Hellships Memorial Foundation strongly recommends:
Formal recognition of the site as the Hofuku Maru.
Designation and legal protection of the site as a maritime war grave.
Preservation in situ (leaving the wreck undisturbed on the seabed) and the implementation of monitoring protocols to prevent looting and dynamite fishing.
International consultation with the descendant communities of the Allied POWs to ensure the site is appropriately commemorated.
