Soule's funeral on April 26, 1865, was attended by a large crowd, with military and civil dignitaries. A journalist described the funeral as "the finest ever seen in this country." Soule was first buried at Denver City Cemetery (now the location of
Cheesman Park). Soule's large memorial stone was not moved with his remains, and he now has a standard soldier's gravestone.
Recognition in Colorado From 1998 to 2019 a Spiritual Healing Run/Walk was held in November to honor those killed at Sand Creek (after an interruption due to the
COVID-19 pandemic, the Run began again in 2024). It began at the
Sand Creek Massacre National Historic Site in southeastern Colorado and concluded on the west steps of the
Colorado State Capitol. Starting in 2003, a memorial ceremony was also held at Soule's grave site, and in addition in later years at a Denver high-rise building where a memorial plaque honoring Soule was installed adjacent to Skyline Park, near the location of his murder. The marker is 100 feet from 15th Street and about 100 feet from Arapahoe Street, behind a black pillar supporting the building at that location. The inscription on the memorial plaque says: :"At this location on April 23, 1865, assassins shot and killed 1st Colorado Cavalry Officer Capt. Silas S. Soule. During the infamous Sand Creek Massacre of November 29, 1864, Soule had disobeyed orders by refusing to fire on Chief Black Kettle's peaceful Cheyenne and Arapaho village. Later, at Army hearings, Soule testified against his commander, Col. John M. Chivington, detailing the atrocities committed by the troops at Sand Creek. His murderers were never brought to justice." ==Legacy==
