of Mechanicville, in the Hudson View Cemetery (see: Col. Elmer E. Ellsworth Monument and Grave). Thousands of Union supporters rallied around Ellsworth's cause and enlisted. "Remember Ellsworth" became a patriotic slogan. The 44th New York Volunteer Infantry Regiment called itself the "Ellsworth Avengers" as well as "The People's Ellsworth Regiment". Simultaneously, Jackson became a celebrated martyr for the Confederate cause. 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). Legacy After the Marshall House incident, soldiers and souvenir hunters carried away pieces of the flag and inn as mementos, especially portions of the inn's stairway, balustrades, and oilcloth floor covering. Relics associated with Ellsworth's death became prized souvenirs. President Lincoln kept the captured Marshall House flag, with which his son Tad often played and waved. The flag apparently passed to Brownell, and upon his death in 1894, his widow offered to sell small pieces of the flag for $10 and $15 each. She presented one fragment to "an early mentor" of her husband's; his descendants apparently sold it more than a century later. 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. 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. Yet another fragment is held by Bates College's Special Collections Library. A fragment bearing most of a star is on display at the Fort Ward Museum and Historic site in Alexandria, along with the kepi that Ellsworth wore when he was killed, patriotic envelopes bearing his image, and the "O" from the Marshall House sign that a soldier had taken as a souvenir. Artifacts collected during the construction of the Hotel Monaco were preserved by local archeologists. They may be seen in the Torpedo Factory Art Center's third floor exhibit (the Alexandria Archaeology Museum), three blocks away on King Street.
