Here are some pictures I finally scanned.
The wall that has the sign on it is from the Japanes Naval Underground Headquarters.
The landscape is from the south coast of the main island right by the "Corner Stone of Peace" memorial.
There castle wall is the rebuilt Shuri Castle wall that was destroyed during the battle.
The wall has some of the sections of the "Cornerstone of Peace." It contains the names of all 237,318 people who died as a result of the battle; Japanese soldier and civilian as well as allied soldiers and sailors.
The thing that looks like a bunker is one of the Okinawan seplucres that dot the island. The were, in fact used as bunkers during the battle.
Lastly, there is a picture of Sgt O'Brien teaching a Chemical Warfare Defense class during my trip there in 1998.
Here is an overhead of the peace memorial.
