Me thinks there may have been a transcription error. Remember we do not have originals of the George Lea Letters. Interestingly, G.F. Foster could have been B. F. Carter since there is a Capt. Benjamin F. Carter Co. B who later became a Lt. Col. The 11th Vols could have really been the 4th Vols. and Foster could have been Carter. This is when an original copy is so valuable...I don't mean to the person who probably sold it rather than preserving it either.
