[4][5] He was killed while removing a Confederate flag from the roof of the Marshall House inn in Alexandria, Virginia.
[6][7] Before the war, Ellsworth led a touring military drill team, the "Zouave Cadets of Chicago".
Ellsworth had studied the Zouave soldiers, French colonial troops in Algeria, and was impressed by their reported fighting quality.
[10] Ellsworth was killed at the Marshall House on May 24, 1861 (the day after Virginia's secession was ratified by referendum) during the Union Army's take-over of Alexandria.
[4][7] Before crossing the Potomac River to take Alexandria, soldiers serving under Ellsworth's command observed the flag from their camp through field glasses and volunteered to remove it.
Once inside, they encountered a man dressed in a shirt and trousers, of whom Ellsworth demanded what sort of a flag it was that hung upon the roof.
[4][7][20] A plaque that the Sons of Confederate Veterans placed within a blind arch near a corner of a prominent hotel that stood on the former site of the Marshall House commemorated Jackson's role in the affair for many years.
However, Marriott International removed the plaque in 2017 shortly after it purchased the hotel (see: Marshall House historical marker).
President Lincoln kept the captured Marshall House flag, with which his son Tad often played and waved.
[22] Today, most of the flag is held by the New York State Military Museum and Veterans Research Center in Saratoga Springs, which also has Ellsworth's uniform with an apparent bullet hole.
[23] Another fragment is held by the Smithsonian Institution's National Museum of American History, along with a blood-stained piece of oilcloth and a scrap of red bunting from the Marshall House.
They may be seen in the Torpedo Factory Art Center's third floor exhibit (the Alexandria Archaeology Museum), three blocks away on King Street.
It sits directly across Waverly Place from the historic Northern Dispensary building and across Christopher Street from the Stonewall Inn.
