Bragg was not a well liked man. More than once his own men plotted to assassinate him just to get rid of him. Let's say one day (you pick the year) one of Bragg's men gets tired of him and shoots him dead. All the officers swear up and down that it was an accident and the matter is largely laid to rest, to be talked about by later historians. What affect does this have on the war? Of course, the year in which he is killed matters loads, but I'll leave that to you. Thanks.
