Didn’t the POWs build the working model of the Mississippi River for the Army Corps of Engineers?
Yes they contributed....there was a model at a Corps facility near the camp at Raymond ..the camp was technically between Raymond and Clinton off Raymond road ....and at a Vicksburg ......I think
I saw them both with my dad when I was young
The POW camp was still standing.....looked like a bunch of army barracks facility ....fenced
Not anything serious like a prison
That usual army wooden yellows tan and white....but yes that model may still be there
There is a baseball field there named for my cousin Buddy Butts who died young at 32 of cancer.....he was a coach of little league forever
