(Great point about Civil War winners and losers, Setanta. Sadly many people both north and south of the Mason Dixon Line still choose sides and hold grudges and stereotypes. Yes, a Civil War thread would surely generate a lot of interest--though I've just begun to plumb the depths of a2k, so it may have already been done.)
Now, a little trick on writing in the Southern vernacular that I learned from a Southern author who has a great ear and is a master at writing Southern dialect: Most people (and I did the same thing for decades) abbreviate "them" as " 'em " when writing dialect. Listen closely as you read these sentences: "Let them go," "Let 'em go," "Let'm go." To my ear, the last version most closely approximates the eliding of the "th"--we don't make separate words of "let" and "em"--we run'm together. "Letum" is probably an even more accurate representation of the pronunciation, but too much literal phonetic spelling can get pretty tedious to the reader.
Oooops, sorry if I've gotten tedious here....
