Hello, I am very interested in this particular group as my great-great grandfather served in this unit under G.O.#3.

I'm looking for any detail on the unit, where it served (my ggg card says Dallas MO. 3/17/1865 - 7/8/1865).

Any links to sites or really ANYTHING is greatly appreciated.
I plan on making a trip to Bollinger County this summer (I live in St Louis) and am hoping to find some great info!
