Moving on to a different general--there was a Union AND Confederate General James Henry Lane. From a quick glance at their records it appears they were in different theaters. I don't know how very helpful that might be, but I suppose it could have gotten a wee bit confusing if they were opposite on another.
General John H. Kelly--age 23 when promoted to Brigadier General. Age twenty-four when he was mortally wounded and died at the Battle of Franklin, Tennessee.
