Lumpy,
Before flight school I was a 113C(N). That is an Indirect fire Infantryman. (Nuclear qualified) Translation? Davy Crocket(a Nuke) and mortar Gunner. That means Maps, Maps, Maps. And my bet is, you can read them as good as or better than any aviator. I know I could. As for the location, It is in the "Vicinity of". There is no doubt the outfit was in the Ia Drang campaign, And that Holliway was the Main staging area for the fight.
We need to ask some of our old gators. We have to flush some of the 64/65 and 65/66 folks out of the woodwork. Maybe then we can get first hand accounts. I will ask Jim Irwin . He was there at that time I think.
