"Blood in the Ozarks" by Clint Lacy delves into a controversial and often overlooked chapter of the Civil War, specifically focusing on Union war crimes against Southern sympathizers and civilians in occupied Missouri. The book centers on the massacre that took place on Christmas Day, 1863, in Ripley County, Missouri, where Major James Wilson's 3rd Missouri State Militia Cavalry allegedly attacked a gathering of Confederate supporters, including women, children, and the elderly. Lacy aims to shed light on this event, known as the Wilson Massacre, presenting a narrative that challenges the conventional historical accounts by providing evidence from local documents, newspaper articles, and military records. The book is praised for its effort to bring forth a nuanced understanding of the brutality of the Civil War in Missouri, emphasizing the need to acknowledge all aspects of this tumultuous period. Lacy's work is commended for its thorough research and commitment to uncovering obscured truths of American history.
