The day after Virginia’s secession was popularly ratified on May 23, 1861; General Winfield Scott ordered the occupation of Alexandria and present-day Arlington County, Virginia. Union troops marched across the Aqueduct and Long Bridge or arrived by steamer. Two weeks later, the “New-York Illustrated News” carried the story with this illustration. These troops were a volunteer infantry regiment of New York firemen under the command of Union Colonel Elmer Ellsworth. Ellsworth modeled his Zouaves on those of the French Emperor Napoleon III’s precision infantry - known for their skill, bravery, and colorful uniforms.
