In 1898, as the United States mobilized for the Spanish-American War, over 60,000 soldiers converged on Chickamauga National Military Park in Georgia, creating the massive military staging area known as Camp Thomas. What was meant to be an efficient training hub rapidly devolved into a public health catastrophe. Military engineers rushed camp construction without proper topographic surveying, placing thousands of open-pit latrines on higher ground directly above shallow limestone strata and unmapped natural drainage lines.
Unaware of the geological plumbing beneath their feet, camp planners ran freshwater piping alongside these unmapped drainage paths. When torrential summer rains hit the area, raw sewage saturated the soil and seeped directly into porous rock layers, corrupting the camp's main water distribution network. Within weeks, Salmonella typhi spread silently throughout the camp, infecting thousands of recruits.
Over 4,000 cases of typhoid fever erupted, causing widespread panic and killing hundreds before a single regiment deployed overseas. The disaster resulted in the famous Dodge Commission investigation, which exposed appalling administrative neglect and fundamentally restructured U. S.
Army sanitation protocols, field hygiene training, and medical infrastructure for future twentieth-century conflicts.
