Dixie: The Second War Between the States (1976)

Dixie appeared in Strategy & Tactics magazine #54, Jan-Feb 1976 as well as a folio edition.

From the introduction:
Dixie is a brigade/division/corps level simulation of an alternate-history conflict. Dixie posits that the Confederate States of America had successfully waged the first American Civil War and survived as an independent political/economic entity. The game further posits that these two independent countries wage a modern war during the late 1930s.

Variant counters and rules were published in Strategy & Tactics magazine #226 - Jan/Feb 2005.
