The Arisan Maru - Worst Single POW Loss

On September 12, 1944, the Japanese transport Arisan Maru carried approximately 1,800 Allied POWs, mostly Americans from Bataan, crammed below deck. The ship was torpedoed by USS Shark. Japanese guards abandoned ship while nearly all 1,800 POWs drowned - one of the worst single-incident losses of American POWs. The wreck was discovered in 2023 at over 1,000 meters depth.
