Calamity at Chancellorsville, The Wounding and Death of Confederate General Stonewall Jackson, by Mathew W. Lively, 2013.
Edited 1/1/2014. Lively is an MD and has some interesting information on the actual cause of death. He also has an interesting theory on the controversy of the location on the ground where General Jackson was wounded. I recommend it for any CW student and especially those interested in General Jackson
Note: I posted this on the Jackson book shelf thread a few years ago. I think it is appropriate here also.
