THanks a bunch mr. Hodge. I have the book on the 63rd Va in Reynolds brigade because my gt gt grandfather was in it. THere is also a new one on the 58th tarheel, but I haven't read it. I hope your book comes out because there is not a lot on cummings brigade. i'll have to re check the info, but the 20th Alabama may have had a lot of men at reorganization after Vicksburg.
Take care!!
