What event does the Confederate Heroes monument commemorate?

The Confederate Heroes monument is designed to commemorate the death of Colonel Dreux, who is recognized as a significant figure in the Confederate Army during the American Civil War. His dedication and sacrifice during the conflict prompted the establishment of this monument as a tribute to those who fought for the Confederacy. The monument serves as a historical marker, reflecting the perspectives and values of the time regarding the Civil War, and is part of the broader narrative of how the South remembers its history and its leaders.

In contrast, the other options do not accurately relate to what the monument specifically commemorates. The Battle of New Orleans was a significant event in the War of 1812 rather than the Civil War. The mention of the First Civil War battle is too vague and does not pertain to Colonel Dreux or the specific commemoration of the monument. Additionally, while the Irish yellow fever epidemic is a notable historical event in New Orleans, it is unrelated to the Confederate memorial and its focus on military figures of the Civil War era.
