The souvenir seems to confirm he was on Leyte with the 767th. It is also possible that Stanton is wrong and all or part of the unit served in the Southern Philippines campaign. For me, when there is an official document that shows a veteran served in a particular campaign and a post-war history disagrees the "tie" goes to the veteran. Hopefully the PANG museum will have more on the subject. I'll keep an eye out for more information (I am trying to locate my copy of Gen. Eichechelberger's history of Eight Army and will check it for references to the 767th when it resurfaces.) Please let us know what you learn from your research. It is always interesting to see how these things turn out.
