Bridge (U.S. Civil War) The 'Bridge' in reference to the U.S. Civil War denotes a strategically important structure that played significant roles during this conflict, particularly during sieges and battles. Notable examples include the Cumberland Gap Bridge in Tennessee, which was crucial for Union forces to penetrate into Confederate territory in the East, and the Elmira Bridge in New York, where a prisoner-of-war camp was located and provided logistical support to the Union war effort. These bridges were often targets of attack due to their strategic positions and were significant factors contributing to the outcome of various battles. The 'Bridge' during the U.S. Civil War represents more than just an engineering marvel; it symbolizes connections, transportation lines, and lifelines that sustained armies and influenced the course of one of America's most pivotal conflicts.
