Battlefield archaeology is the study of historical battle sites through the examination of artifacts, structures, and landscapes. This field combines techniques from archaeology and history to uncover information about past conflicts, including the strategies used, the soldiers involved, and the impact of battles on local communities. Archaeologists often use tools like ground-penetrating radar and metal detectors to locate and analyze items such as weapons, uniforms, and personal belongings. By understanding the physical evidence left behind, researchers can reconstruct events and gain insights into the experiences of those who fought in battles like the American Civil War or World War I.
