Where where the marines that died on Iwo Jima re-interned?

Answer 1

Most US foot soldiers, Army or Marine, who were Killed In Action are currently working on their third or fourth burial. Ultimately the next-of-kin of the killed soldier or Marine was contacted in the years immediately after the war and given the option of having the remains of their loved one returned to the states, where they could be buried anywhere the next-of-kin wished, including any of the National Cemeteries, such as Arlington. For those who chose to leave their lost son among his comrades the National Memorial Cemetery of the Pacific was established in the late 40s, in Honolulu, Hawaii, in the crater of an extinct volcano called The Punchbowl. Undoubtedly the majority of those Marines killed on Iwo Jima who were not returned to their families in the states are there today. They would have been first buried on Iwo, then removed and reinterred on Guam, again temporarily, until The Punchbowl was created.

The American Battle Monuments Commission operates more than twenty cemeteries in foreign countries for US service personnel killed in wars, mostly containing WWII personnel. The ABMC does not operate The Punchbowl, which is on US soil, and contains the remains of Americans killed all over the Pacific. The ABMC does have one cemetery in the Pacific, at Manila. I'd guess that it mostly contains men who were killed liberating the Philippines, but there may be a few Iwo men in there also.
