@bdtex It seems that the stop in Greenwood was a great way to end the CWT Tour. You visited site of one of Grant's early attempts to reach Vicksburg and you also saw the grave of a Confederate soldier who surrendered at Vicksburg.
Here is my quick research of this Bains Battery, aka Vaiden Light Battery.

I'm still not clear as to where the guns were that fired on the Cincinnati OR if the Vaiden Light Artillery would have been able to fire on it from this position.
