I have found some answers to the questions I posted above ("looking for background info"), in case there is still some interest on the subject.

Briefly; I had found an account in the memoirs of an Irish Brigade soldier of a little girl killed accidentally by federal cannon fire at Charlestown WV in Oct 1962. I wanted to know more about the incident; who were the CSA forces, etc.

I have summarized what I've since learned below:

A reference entitled, "The war of the rebellion: a compilation of the official records of the Union and Confederate armies" states that on Oct 16/17 1862 during a Reconnaisance from Harper's Ferry to Charlestown WV - and "a skirmish enroute" the union senior Federal officers present were Generals WS Hancock and JC Caldwell.

The same reference states that Col. Thomas T Munsford was commanding the Second Virginia Cavalry (listed as Second Virginia Infantry in another document). The Second Virginia later became the Fifth West Virginia Cavalry.

Hancock and one of the junior officers present (Maj FA Walker) had some corespondence during these days, and very little to say about the actions - but they did discuss confederate troop locations and movements. They did mention some skirmishing and small numbers of casualties.

I've found Munsford's comments for the same period of time. He made only general comments about the location, over the few weeks he was in command there.

I still have not found any specifics on the incident of the little girl accidentally killed by federal artillary fire. What was her name? Are there any other accounts of the incident? Is there a memorial to her in WV?
