Gen. G.C. Buell ?
Edit - Don Carlos Buell, who made the quote about Bragg's army, had a cousin named George Buell, who also served in the Union Army and attained the brevet rank of brigadier general.
If you had just said "Buell," as many contestants did, I would have assumed you meant Don Carlos. But I have to interpret "G. Buell" as referring to George.
