This thesis examines the validity of using miniature wargaming to study the American Civil War. The analysis specifically examines the miniature wargame rules, STARSNBARS III. The goal is to determine whether Civil War combat can be accurately simulated with miniature wargaming. The study first examines the simulations rule mechanics to determine their historical soundness. Infantry, cavalry, and artillery combat are each examined in three sections unit organization, maneuver, and firepower. Each section is subdivided into three areas for analysis First, an overview of how the section is simulated Second, an historical overview of the section and, finally, a determination of historical accuracy. The rules are then applied in simulating two historical Civil War battles. The battle of New Market is gamed as a controlled reenactment the results of which are compared against the actual battle. The battle of Cedar Mountain is executed as a free-flowing wargame to evaluate historicity. The overall conclusion of the study is that, although not exact, acceptable accuracy can be achieved in simulating Civil War combat. Wargaming can be used to study history. In historical simulations, gaming and history complement each other in building a more complete understanding of the periods warfare.
