"What If . . . ?" Every Civil War armchair general asks the question. Possibilities unfold. Disappointments vanish. Imaginations soar. More questions arise. "What if . . ." can be more than an exercise in wistful fantasy. A serious inquiry sparks rigorous exploration, demands critical thinking, and unlocks important insights. The Great "What Ifs" of the American Civil War: Historians Tackle the Conflict's Most Intriguing Possibilities is a collection of fourteen essays by the historians at Emerging Civil War, and includes a Foreword by acclaimed alternate history writer Peter G. Tsouras. Each entry focuses on one of the most important events of the war and unpacks the options of the moment. To understand what happened, we must look with a clear and objective eye at what could have happened, with the full multitude of choices before us. "What if" is a tool for illumination. These essays also explode the assumptions people make when they ask "what if" and then jump to wishful conclusions. This collection of thoughtful essays offers not alternate histories or counterfactual scenarios, but an invitation to ask, to learn, and to wonder, "What if . . . ?"
