Thanks, though.
That could be a problem but not impossible. About three years ago, I found one of the men who wrote a set of letters in a suburb of Chicago and called him. He was the one who wrote from the Mariana Islands. He was very lucid. We had a very nice conversation. I can give you his name off the board, but I don't know if he is still in yahoo people search or where now. Things happen fast when people get old. I could give you several names, and you could see if you could find them. I have all the letters sorted by name in ziplock bags except for a few miscellaneous.
One thing you could do is go to www.rootsweb.com and see what mailing lists they have. They have one for WWII, I think, was on it for awhile. They also have archives going back several years you can search.
And I made a mistake. Tojo was in a hospital in Yokohama, not Hiroshima. When I don't work with data for awhile, I get foggy.
I tried to call several people from my letters, but could only find the one, didn't try to find them all.
You could also check with the Navy bases and see if they can help. Large military installations usually have historians. Just suggestions.
