Name That Trauma:: Gary O. on a Melting Face and a Time Trip Witch

I hope you can help me find a traumatizing movie from when I was a kid. I think it was a '60s movie. All I remember is that it was set in the early 1800s, had something to do with a witch and at the end a soldier dies and his face melts. I kind of sorta remember something about a time trip between the 1800s and current day, but I may be mixing that up with another movie. Hope you can help.

Thanks!
