I grew up in Helena and never heard anything of a Confederate POW camp in Helena. There was a real POW camp in West Helena on the main drag, however, and it housed Italian and German prisoners from WWII. Perhaps this is how the confusion started abt Helena being associated with a POW camp. It was a satellite camp of the main POW facilities scattered around the state. Arkansas even had at least one camp for relocated US citizens of Japanese descent. Many of the Italian and German POWs were hired out to local farmers in Phillips County.
