Thank you for these great pictures.
One of the USMC Oral Histories I have, recounts what happened at Marpi Point. Marine interpreters begged the Japanese Civilians not to commit suicide, yet they persisted by the 100's.
No need to go into details, but it was horrific.
Book is "Semper Fi, Mac", and the author's last name is "Berry", I think. An excellent read, if you enjoy that sort of thing.
