The 36-day assault resulted in more than 26,000 American
casualties, including 6,800 dead. Of the 20,000 Japanese
defenders, only 1,083 survived.Twenty-seven Medals of Honor were awarded to Marines and
sailors, many posthumously, more than were awarded for any
other single operation during the war.http://www.history.navy.mil/library/online/battleiwojima.htm
We should have annexed it after the war.
I am surprised so many Japanese survived. I would have guessed maybe 15-20 instead of over a thousand. I suspect many of them were badly wounded and unable to resist.
